    ross trigger kit rb26

    Iecku, I just thought I would mention a little bit of info that many people miss. These kits appear to use the Honeywell 1GT101 sensor, these sensors are much slower on the rising edge than the falling edge. The datasheet quotes a 15µs rise time Vs 1µs for fall time. So for at least trigger 1 (that controls the timing) it would be more correct to set the trigger edge to falling. Even though 15µs is only like 0.9 deg at 10000RPM, if you can get extra accuracy just by a simple setting change - then you might as well use it...

    Hi All, The developers of RealDash have been working with us to make their app compatible with Link ECU's. It is now compatible. For those that havent seen it you can learn more here: http://www.realdash.net/ In my short play it seems to work well and has lots of cool features. Lap timing, navigation, configurable alarms, live graphs, live streaming of data, music player, etc. The app and a selection of basic "skins" are totally free, then there are some more fuller featured paid for "premium skins" that do more stuff such as data logging and may look cooler these are still relatively cheap ranging about $3-$10. One example below. Right now it wont work on the Atom, Monsoon, Kurofune or Black Storm as the serial stream is not enabled in those ECU's but we hope to enable that setting in the next couple of months. Right now it will work in the Blue Storm, Xtreme, Fury, Thunder, all Plug-ins & Force. It will also work on old G4/Vipec V series ECU's. Connection to your tablet/smartphone is direct using your normal Link USB tuning cable, for phones/tablets that only have a micro USB port you will need a "Micro USB OTG adapter". Instructions for setup and connection attached to bottom of this post. RealDash.pdf

    Hi, Currently with mixture map you set a threshold so that samples within say 25% of the centre of a cell vertically and horizontally. This pool of results are used to contribute towards an average value in the centre of the closest cell. However this means that you've got 25% variation of rpm and load, contributing to a static value in the centre - and you need to throw away 75% (?) of recorded values. I have another idea that can let you use all of the data instead, and improve the results. For simplicity's sake imagine a 4x4 grid, and our current load and rpm point is 25% of the way towards the lower RPM value and 25% of the way towards the lower Load value. If we interpolate these values, as per what the ECU does. Note: I have just titled the columns and rows with percentages to show what percentage of the each cell we are interpolating from. We get a value of (25% * 25* 10) + ( 25% * 75% * 30) + (25% * 75% * 20) + (75% * 75 * 40) = 0.625 + 6.075 + 3.75 + 22.5 = 32.95 is the table value that interpolation produces. Now lets say that you wanted to add 10% to this value. If we just adjust the closest cell by 10%, as per current Mixture Map strategy. Then our bottom left cell changes to 44 so our table now looks like this: If we do the interpolation again, but with the new value to represent running the car again after the update: We get a value of (25% * 25* 10) + ( 25% * 75% * 30) + (25% * 75% * 20) + (75% * 75 * 44) = 0.625 + 6.075 + 3.75 + 24.75 = 35.2 as the new overall value. Which is only makes 6.8% difference to the interpolated value, rather than the 10% we wanted. On the other hand... If PCLink De-interpolated the 10% that it wants to add. Instead of adding 10% to the one cell, we split the 10% addition across the 4 cells based on the same percentage that the value was interpolated from initially. So: Top left cell: (10 * 1.1 * .25 * .25) = 0.6875 Bottom left cell: (30 * 1.1 * .25 * .75) = 6.1875 Top Right Cell: (20 * 1.1 * .25 * .75) = 4.125 Bottom Right Cell: (40 * 1.1 * .75 * .75) = 24.75 = 35.75 is the table value that de-interpolation produces. We were trying to add 10% and this new value produced is 10.5%. So that's pretty good! (The 0.5% error comes from rounding to 3 decimal places in my example) So it's accurate to the provided data in every instance. Which is especially relevant when it's applied 1000s of times across all of the cells. You dont need to throw away any of your recorded data, it all contributes to the cell values. Mixture map is pretty good for roughing out a map initially but because of the inaccuracies of the "nearest cell" method I don't really use it that much anymore when trying to dial in a fuel map. You always overshoot or undershoot unless you set your cell tolerances impossibly tight and have millions of samples. And, since this is all only done in PCLINK rather than the ECU, there's not really any worry about the overheads of the extra maths involved. It's worth having it chug away for a few minutes longer if you can get an awesome result on first or second iteration of Mixture map logging. So - that's my Friday night suggestion. Thanks for reading if you got this far, haha.

    Hey people, Just thought I'd post up a quick note about something I did recently that worked out well. I was wanting to optimise ignition timing for cruise, so using some switches on my dash to trigger a combination of datalogging, 4D ignition, 5D ignition and the 2nd ignition table set to overlay mode. With the idea that I could add or remove timing from the main table in varying amounts without having to stop the car, and datalog the whole lot easily. Like so: Since you can turn on more than one ignition trim table at once, using those three you can get a combination of timing settings which I then marked on the switches. So +1 degree, + 3 degrees, +5 degrees, etc. I completed a run on a particular stretch of motorway that has lots of ups and downs, with cruise control turned on at a speed that's at 3250rpm in 6th gear. Then flicked the first switch, did it again. Flicked second switch, did it again, and so on. When home looking through the data, bringing up a time plot with instant fuel consumption and throttle angle it was very easy to see which timing gave best economy. However a secondary method of checking fuel consumption overall is to create a "statistics" page and bring up wheel speed and instant fuel consumption, and look at the mean values: Then from here I've made a quick excel sheet that converts it to Litres per 100km: Then from here, collated the results from each run. So based on this it's pretty clear that an additional 9 deg advance made the engine pretty happy on those particular cells, so updated my ignition table and readjusted some of the surrounding cells to more sensible values too. It was a fairly time consuming exercise but it's amazing to see how much fuel I have been throwing down the toilet just based on under advanced ignition. It was also interesting to see that at 100kpa my car only has 14 deg ignition at that rpm, but then by 70kpa it's wanting 33. (The goal AFR changes though, to be fair... 15.2:1 goal AFR for cruising) Since changing the timing the car is a lot quieter too! I am guessing because when you dont have enough timing, the flame front is still expanding when the exhaust valves open. So instead of having energy push the piston down, it's coming out the exhaust as noise and heat.

    EFI University or HPA?

    Hi Grant, In case my user name didn't give it away, I'm Andre from HPA We went down the path of online training because it allows us to help more people all around the world, and we firmly believe that it offers significant advantages to in-person training. It's a cost effective option since you don't need to travel, and you also have the advantage of being able to re-watch our courses as many times as you like. This means you can brush up on concepts that you're not clear on, or revisit concepts that you've perhaps forgotten since initially taking the course. The key to our courses though is our support community which is where we bridge the gap between online and in-person training - We believe strongly in supporting our members and this is where our private online forum and our regular weekly webinars help back up the course material. The forum is the perfect place to get fast and reliable answers to your questions, while our weekly webinars are the fastest way to expand your tuning knowledge on a range of engines and platforms, as well as staying up to date with the latest technologies. I couldn't agree more with Ben's comment about the requirement at some point to transition into hands-on experience and that's exactly why we developed our 'remote practice dyno' where you can get real world hands-on experience tuning a real engine on a real engine dyno without leaving your house. The online practice dyno is currently operating a Link G4+ Fury ECU which may be helpful to you given you're on this forum. You can find out more about the online practice dyno here: We understand that buying online education can be tricky and we want our members to be able to purchase with confidence which is why we also offer a 60 day, 100% money back guarantee - If for any reason you feel our courses aren't right for you, we will refund the full purchase price. If you're interested in getting a taste of what HPA is all about then I'd suggest you start by signing up for our free six-part series of lessons. This will give you some insight into how we work and what we can offer: https://www.hpacademy.com/free-tuning-lessons In the perfect world I believe the best solution is to get as much training as possible - Both in person and online. I found that when I was operating my own performance workshop however, that unless the in-person training was local, the cost of training staff in this way was usually prohibitive. I'm happy to answer any questions you may have

    Logging setup for ECU logging

    Yes, that was one of the first Efi engines I done about 20 years ago when I was a teenager. Motec M48. Couldn’t get many SR20 parts in those days so had to make throttle bodies, camshafts, dry sump system etc from scratch. Datsun 510 rally car.

    Guys relax a bit. I've mapped and I'm supporting several 600-800hp 2.0 to 2.3l time attack engines/cars with a Link ECU and multimap strategy. Such an engine runs usually for 5000 race track kilometers until a rebuilt is needed. That's a similar distance to a 24h race. I like to answer your question.: All LINK ECU use the same PC-Software and the same Firmware. The main difference between all LINK G4+ ECU's is only the hardware. your tuner should tune the main Fuel and ign Maps from the lowest to the highest boost levels. There are 3 main Boost Maps in the LINK ECU. You can additionally span one of the axis of the Boost Wastegate or Target table to a driver Rotary Switch. So it's possible to have up to 33 different boost maps, which all can be switched on the fly. On top of that, you can activate 4D fuel and ignition tables on one or several of the boost maps. This allows trimming Ignition and Fuel on some maps if you or your tuner like to do that. The Link Ecu is really flexible. Usually, the only limit what you can do is the creativity of the tuner. As an example, we installed 3 rotary switches in a Time Attack/ Hillclimb car. One 12-Position Rotary Switch is used to choose between 12 different torque maps (mainly altered by boost strategy). The Launch RPM can be chosen over another 12-Position Switch, depending on whether and Track conditions. And lastly, we have a 3-Position Rotary Switch to choose one of 3 Drive by wire Throttle Maps. For engine Safety, we set up Limits for too low and to high Coolant temp, Oil temp, Oil press and Fuel press. We are also using full time closed loop lambda and sending a lot of Data over a custom CAN. As you see, the LINK is a very capable system. But as every ECU, it needs a capable tuner to use it properly.

    Closed Loop fuel trims

    Regarding Lambda control error correction table. I spend alot of time to tune these. The base map is adjusted the wrong way around. Because the error correction tables is a % corretion of actual error, you want big corrections like 15% on small errors (0.03 lambda error) and small correction (like 5%) at the biggest error on the table. This is because a fuel film built up first in the ports when big correction are applied. This means it needs several burn cycles to get the whole change applied and measured. This means lambda control applies big changes two or three times for big corrections which leads to Lambda oscillation. On small changes fuel film built up is much less. Lambda change is done and measured much faster and within same burn cycle. This means the Lambda correction can be set much higher, because the change in AFR is measured instant. I have attached a tuned example.

    EFI University or HPA?

    Hi All, Ben here from EFI University. Honestly, you really can't go wrong with any of the choices out there. Ben and Andre at HPA do a really great job and we have nothing negative to say, in fact a lot of our customers tell us they've used both and learned things from both. We try really hard to focus on giving our clients a real world "experience" by letting them actually put their hands on the dyno and doing the work. It's obviously a different approach to the learning process than an online experience, and we realize that due to cost and time not everyone can take advantage of this platform so we do offer some online training as well. As we move forward we may offer more of the online stuff based on requests from customers, but it's unlikely we'll ever transition to online only as it just doesn't stack up in real value to the customer the way a true hands-on experience does. I always like to use flight training as an example...you can only play on Microsoft Flight simulator for so long and eventually you HAVE to get into the airplane. No matter what, the experience will be different in real life so while we absolutely agree there is value in online video based training, our focus will always remain on training in a real world environment. I hope that was a helpful introduction and explanation of our core philosophy and if anyone had any questions don't hesitate to call or drop an email! Thanks, Ben Strader, President, EFI University, inc

    The continental Ethanol Content Sensors will read significant lower when low flow goes through the sensor. This means during a WOT run the ethanol content will read significantly lower at high load and rpm than at idle, because the flow in the return line is low. I attached a Log to show the problem. With more boost, I see values 20% lower at WOT than at idle. This is a well-known problem and other ECU manufacturers have an Ethanol Clamp function for a good while. The Ethanol content does with activated clamp function only update when the Injector Duty Cycle is below a certain level. Once the INJ Duty Cycle is higher than the threshold the ECU takes the last value read below the threshold and update Ethanol content only when InjDC goes below the threshold. So a quite simple function, but with a big need! Please implement it asap. Thank you.

    Thank for Realdash developing such a powerful app that I don't have to buy expensive AIM racing instruments. My car is Subaru GRB, ej25 with link G4 + thunder. I developed a protocol conversion module using STM32. Then can convert the Can signal of the link G4+ into a Realdash protocol, and then connect to the mobile phone through a TTL to Bluetooth module, so as to display almost all the data on the mobile phone (as long as the PClink can display).

    Nos control

    I think its much better to have all universal function like virtual aux, timers, 4D, 5D, fual fuel table etc. than a dedicated NOS function. This way you can build your own NOS function excatly how you want it. You just habe to be a bit creative with the universal functions.

    CANBUS OIL Temp from AN8

    Hi Mark, I suspect the problem is your oil temp sensor being on a AV input is not actually assigned to the "oil temp" parameter but rather a "GP Temp" parameter that is not sent in the standard generic dash stream. Attached below is a configurable version of the generic dash stream where I have replaced "oil temp" with AN 8 - Oil temp. MarkHellier.lcs For any others that want it I will also attach an un-modified configurable generic dash stream. Configurable Generic Stream.lcs

    Closed Loop fuel trims

    Hi Marc Good to hear back from you. How much does your AFR oscilate? Where is the wideband located? Depending on position, you need to adjust Lambda rate and Gain. You should do some testing. Tune your VE table with CLL off as good to your Target AFR as possible. Adjust your target AFR table to the rich side with one task by the amounts listed in the gain table 0,33 0,66 etc. And log, with a high logging rate, how long the sensor needs to get to a stable reading. Lets say it needs 0.3 seconds. This means your frequency in the lambda rate table may be max. 1/0,3 = 3.333 This test should be done at different loads and rpms to work out best CLL settings. Best place to do that is a load bearing dyno.

    [UPDATE] PCLink 5.6.5.3338b Released

    Hi, to use the Link software as Dash in the next update you could remove the outer frames of the watches and always be in front. This way it could be configured similar to a Motec or other Dashboards The Dial gauge RPM could also be improved with a more "Racing" look I attach an example

    Wire schematic

    Hi To speed up wiring and diagnostic I would like to have a function that outputs a list, a schematic, and a picture of the connectors with all labels of all configured (assigned) in- and outputs. On top of that many smart things could be implemented like an auto updated complete wiring schematic in an easy understandable format(e.g MS Visio style). These things can speed up install time and wiring a lot, which sets barrier lower to switch to a standalone ECU. possible examples attached.

    Glad you got it sorted out Idris. But if you would like to get better information from the members of the forum, it would help if you supplied a bit more information with your questions. Different engine combinations sometimes benefit from different settings. And with your rather vague post, there is not much to go on to give you good suggestions. I hope this helps with your further posts on this forum. Have a nice day.

    Good morning everybody, Last night we released a new PCLink and Firmware, I updated this thread but it didn't stick (weird eh?) Thanks for your patience with the 5.6.2 to 5.6.5 update-requiring-ECU unlock bug. Thanks Davidv for his work around. I'll leave these notes attached because they're still quite relevant to this release: As always, here's how to update your firmware the best way:

    For anyone else looking to run similar setups with Racepak dashes and a link ecu. Don't purchase the Racepak display dash or logger dash that has the standard 5pin v-net connector and 8pin Deutsche connected on the back. If you purchase the Racepak STREET dash it has a can module already built into the dash that can be programmed to most new ecus and I have tested and confirmed it on my link G4+ extreme.

    Link G4+ Tablet view

    After doing a bit of research recently into running a tablet as the primary dash for my car here's some thoughts... Hardware: For the older Windows tablets using Micro usb you should be wary of any claims of being able to charge and have a device connected, a lot of descriptions of the adapter cables are wrong as it totally depends on the tablet, so make sure you do your research first, if in doubt it likely doesn't support both at same time. However I believe the new tablets which support USB C may be better in this regard, again do your research first. Performance of PcLink on lower speced windows tablets (1.3ghz quad cpu, 1gig ram etc) is actually very good, PcLink will be very slow as the software initially connects to the ecu, and the display wont respond for a good 10 seconds, but once it syncs up it works perfectly. Here's my 8 Inch acer tablet with Windows 10 and PcLink with different layouts Because I could not charge and display data at same time I just ran it on battery, it lasted for a good 5-6 hours which was impressive. To me there's no point in having a tablet that can't charge and display so I replaced the above with a Lenovo ThinkPad Tablet 2 (2 usb ports, 10 inch) with Windows 10 and PcLink This charges and runs at the same time which is perfect. Setup: Setting up PcLink for the tablets is a bit of a pain as PcLink doesn't support touch very well. The easiest way is to have another pc with PcLink running and do the setup on that then transfer the layout files across. Your best to set the resolution of the display on your laptop to match the tablet as otherwise positioning of elements is very hit and miss (especially with high res displays) the ThinkPad I brought has a pen which made resizing and moving elements actually doable on the tablet. Note there is an issue with PcLink and some tablets (My acer one doesn't have this issue) where they throw a "Access violation at address 00000000 in module 'PCLink.exe'. Read pf address 0000000." same as this thread http://forums.linkecu.com/index.php?/topic/6144-access-violation-at-address-00000000-in-module-pclinkexe-read-pf-address-0000000/ It appears to be to do with the 3d chart display and it's very frustrating as PcLink is unrunnable as it triggers the error when ever you open PcLink and when it occurs it stops PcLink from working correctly. You can work around this by running PcLink on a normal pc, getting rid of the default layout with a simpler one then copying the entire folder "C:\Link G4\PCLink G4+" directly to your tablet (this means the software wont try and load the default link layouts which cause the crash). Once you have done this then you can just import layout files as normal (just make sure you use non 3d gauges). Hopefully they fix this at some point (even if it's just disabling 3d charts rather then crashing). As an aside PcLink is inconsistent with how it handles limits on displays, i.e analogue vs digital are configured in different sections of the app, Once you realise this then configuring it's not to hard, however I still haven't found a way yet to get rid of the decimal point on the km/h. PcLink has options for automatically going full screen, and auto connecting which are easily turned on through the menu. Then in windows I have set it as a start up app so it opens automatically, and have changed the user account to go straight to desktop rather the sign in screen (this is a bit more work involving regedit, guides can be found online for both). Realworld Performance: You can see me using my 8 inch tablet in a race here (fully on battery). It performed flawlessly, however as you can see in the video glare is an issue with these tablets (visibility was ok from the drivers seat but could be better), so if using as your main dash then a hood/cover is something you want to look into fitting.

    I would say the timing doesnt look unusally high for 8.2CR with E85, but it also doesnt look tuned at all to me, it looks like someone has just made up the numbers. Why have so many rows with exactly the same numbers on them? You would be better to just delete them all. Seems pretty odd to have the same timing at 207Kpa than you have at 138Kpa. And as JMP says, that big step between 1500 & 2000 is gnarly.

    We see lots of wideband controllers here, the worst for sensor failure are AEM, Innovative seem to be better, there is a noticeable difference as you really don't see sensor failing that often on the LINK CAN Lambda, we put the sensor failures down 100% to the heating strategy not shocking the sensor and allowing time for residual water / condensation to be cleared. The other thing is that the AEM sensor supplied with the kit does not appear to be bosch, but although you could argue that is the reason they fail, replacement genuine bosch dont seem to last that long either. That is the main reason we try and get people to buy the Link sensor and we always ask about the placement of their Lambda bung. PLUS you get EGT with the Link CAN Lambda an invaluable device that has saved my customers $1000's in turbo rebuilds.

    There we go. Granted the RPM line itself is smoother than what i suspected. Could be because of slow logging rate. What gives it away to me though is looking at the RPM ROC parameter. Thats RPM Rate Of Change. How much the RPM changes over a second. Anything over 0 meens RPM is rising at a certain rate and below 0 means its falling. We bot KNOW you are accelerating so the CRANK is certainly not slowing down, right? However you can see i both my screenshots that the ECU is logging a very erratic RPM ROC. It should ALWAYS be on the positive side when the engine is accelerating. That IS the CAS flapping around. There is also some knock registered in one of the logs. I bet because of unstable timing. Never mind me saying it looked smoother than expected. I just wasnt looking close enough at it. Its actually one of the worst i have ever seen You sir, are going to install a cranktrigger before it breaks down completely

    water meth injection

    You will never see 300psi, nor will 2x1000cc nozzles be as efficient as smaller nozzles. Well other than when the pump is pumping against the closed valve and if the pump has been adjusted to see a higher pressure. In fact, with nozzles that large I'd be surprised if you ever see much over 100psi. The pumps simply do not flow what the suppliers claim, and any pressure claims are against a dead head. I've tested the AEM big pump under load and in the real world at pressures required....realistically they're only around a 1200-1300cc pump, and that was with a quoted 1600cc worth of nozzle...and tested not fighting against boost pressure which would reduce flow further. Even with only a 600cc nozzle...my factory set 200psi pump, could never create 200psi. With 1600cc worth of nozzle, in the car, in real world use max pressure I see is around 140psi....so if using say 40psi boost, that's now only 100psi of effective pressure to inject, so even less flow. But stick a pressure sensor on the line and log it for yourself and use this to control any fuel/spark adjustments, rather than what you're currently doing which offers no failsafe. It's a cheap and easy way to monitor what the system is doing, and could be an eye opener. It's a pity nobody seems to have done much testing on the various systems and pumps out there to prove or disprove the suppliers claims.

    2JZ Bosch 74mm DBW idle position table

    Did you have a mechanical throttle tuned with reasonable idle before you swapped to the DBW kit? There is no magic number for ethrottle idle and it depends what RPM you want to idle at, and how much ignition advance you have. More ignition = less throttle needed for the same RPM (and vice versa). Assuming roughly stock internals and ~15* timing, you probably want the throttle angle to be about 3-5% once warmed up, and up to 5% higher at 0 Deg. Before you even worry about fine tuning the idle base table, warm up the engine then zero out the idle table, start with your ethrottle target table: the top "0" row - you want somewhere between 2 and 4 in the columns around idle (500-1500rpm?), and either tapering out to 0 above 2-2.5k, or holding around 2% in that whole top row (depends on how much engine braking you want - zero's = more engine braking). The idea here is that once warmed up, the engine should be close to but just under normal idle rpm with the idle table zero'd out (much like setting idle screw on a mechanical throttle). You can only go in 0.5% increments in the throttle target table. you also want to turn off idle ignition control for now as it will confuse things, and make sure ethrottle idle is set to open loop. Now go to your idle base table that you zero'd out earlier, and set the value for the warmed up temp (80 deg C ish) to 0.3 or 0.5 or whatever gets you the idle you want when warm. set this same number for every temperature above 80 as well. Now add 0.5 for each 10 deg cooler than 80. so if your 80 deg idle number was 0.2, 70 would be 0.7, 60 would be 1.2 etc. This should put you in the ballpark but probably slightly high while warming up. Now turn it off and leave it overnight to cool. Once really cooled down connect a laptop, make it so you can see the rpm, target rpm, ECT, and the idle base table. Start the engine and wait ~5 seconds for post start enrich to drop off, then look at which temp you are at in the base idle table. wait until you warm up enough to be dead center of a cell then quickly change it up or down until the idle RPM is correct. Wait a minute or so until your temp is dead center of the next cell, then adjust that cell so idle matches what you want. Just sit there watching it warm up and adjusting the cells as you hit them. Once its fully warmed up, you can look at tuning ignition idle to make it a bit more stable. I wouldnt turn on Closed loop ethrottle idle though until the next firmware as there are currently some bugs in it where it will add in 0.4% throttle angle every time you get on the gas pedal at idle and can work its way up to being too high. You now have a pretty well tuned throttle angle for warm up. extrapolate out from your final values to anything colder than you actually tuned to complete the idle base table. Remember, if you change the ign angle at idle you may have to re-tune this.

    FIC 1650cc Subaru Injectors

    I switched to these injectors because they're stainless and to handle a bigger turbo with E85. In case anyone else is looking to run them I got injector data (attached) from FIC. I combined this data with the custom flow data i got with the injectors and i've been very happy with how they've worked. Link ECU 1650cc.xlsx

    Knock Control G4+

    It would be nice if these base tables could self populate whilst performing a known "safe" run to fill in the base tables with a background noise level. Then simply add the 10-20% to those values the table could average over a few pulls if need be.
  40. 2 points
    Copy all the injector data from the base map "G4+ Xtreme Black Sample.pclr". This map is from one of our test cars that uses those injectors and we have tested them in-house. For an engine size of say more than about 500cc/cylinder with 1000cc injectors I would say it is not so critical as the idle pulsewidth is usually still in their linear region. It gets more important with larger injectors or smaller engine capacity from here.

    Link CAN lambda and methanol

    My 2 pence worth , 0.65 on Meths is super rich but the difference between 0.8 and 0.65 lambda is safety the power difference will be very small from what I have found. We we was running a methanol drag car we was running NTK sensors but was only using the lambda's as a reference we looked upon the EGT's to get an better idea on how the car was running. Running CLL on full throttle on the Link is something that I would like to do but we dont have the ability to change the closed loop control from low load to high load like Syvecs. I.e have a much smaller adjustment parameter when on high load parameters and it would be good to have the ability to change the CLL % to a different figure from +(add) to -(minus) again like Syvecs.

    Crank trigger tooth count

    I assume we are talking Evo 9 Mivec? If so the mivec cam position is done by a separate sensor to the trigger “sync” so you are free to change the trigger. Note you will need to remove one tooth from the exhaust cam if you are changing to a generic multi tooth or missing tooth crank. Benefits of a higher tooth count is more correct/stable ignition timing during fast transient conditions so if retuned you can often run more timing before the knock limit is reached.

    Start Up Momentary Switch Wiring

    Starter Control Starter Control provides ECU managed operation of the Starter Motor. There are two requirements for starter control to function: · A Digital Input Function must be setup as Start Position. This could be a conventional key activated ignition switch or a push button. and · An Auxiliary Output Function must be setup as Starter Solenoid. This output should be connected to starter solenoid relay. Starter Control Settings Start Switch Mode Selects the mode of starter control. Options available are: · OFF - No starter motor control by the ECU. · Test - Use for testing input/output functionality only. When Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. No other conditions are checked, this could potentially lead to starter damage, engine damage or personal injury if operated at the incorrect time. · Normal - Behaves the same way a typical vehicle starting system. The key is turned and the engine will crank until the key is released. However it offers the added protection of preventing the starter being engaged at a high engine speed and the option to disable starting if the vehicle is not in Park/Neutral or is immobilised. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park Lockout are met AND Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. The auxiliary output will stay active until the Start Status turns off OR the the Deactivation RPM is reached. · Start/Stop - Allows the use of a single button for both starting and stopping the engine. When the engine is stalled, pressing the button will crank the motor over. Once the motor is running, pressing the button again will stall the engine. This mode is suitable for a single start/stop button on the handle bar of a motorbike or jet ski. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park Lockout are met AND Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. The auxiliary output will stay active until the Start Status turns off OR the Deactivation RPM is reached. Once the engine is running, if the engine speed is above the Deactivation RPM AND the Start Status becomes active the ECU will apply a 100% Fuel and Ignition cut to the engine. · Touch Start - Allows a starter motor button (or key) that can be momentarily pressed to start the engine. The driver taps the button and the ECU will take care of starting the engine. Typical applications for Touch Start mode would be remote starting or a jet boat. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park Lockout are met AND Start Status is momentarily active the ECU will activate the Starter Solenoid Auxiliary Output until the Max Crank Time is met or the Deactivation RPM is reached. As of firmware version 5.5.6, pressing the start button again while the engine is running will stop the engine. Starter Deactivation RPM Specifies the engine speed (RPM) above which the Starter Solenoid Auxiliary Output turns OFF. Use Anti-theft Lockout An option to make the Starter Solenoid Auxiliary Output conditional upon Anti-theft status. If set to Yes and Anti Theft Status is Active the Starter Solenoid Auxiliary Output will not function. Use Neutral/Park Lockout An option to make the Starter Solenoid Auxiliary Output conditional upon Neutral/Park status. If set to Yes and Neutral/Park Status is OFF the Starter Solenoid Auxiliary Output will not function. Max Crank Time Used only on Touch Start Start Switch Mode, this is the maximum amount of time the starter will be allowed to crank if the engine does not start. Starter control Examples Example 1: Normal Mode with Anti-theft Assume Starter Control is set up as: Start Switch Mode = Normal Starter Deactivation RPM = 600 RPM Use Anti-theft Lockout = Yes Use Neutral/Park Lockout = No With the above settings the ECUs Starter Control would activate the starter motor if: · Engine speed is less than 600, and · The anti-theft signal is off and · The driver presses the start button (or turns the key). Example 2: Start / Stop Mode with Neutral / Park Lockout Assume Starter Control is set up as: Start Switch Mode = Start / Stop Starter Deactivation RPM = 550 RPM Use Anti-theft Lockout = No Use Neutral/Park Lockout = Yes With the above settings the ECUs Starter Control would activate the starter motor if: · Engine speed is less than 550, and · The Park/Neutral signal is active and · The driver presses the start/stop button. With the above settings the ECU would apply a 100% cut to both fuel and ignition if: · Engine speed is greater than 550, and · The driver presses the start/stop button. Note: The fuel and ignition cut will remain until engine speed is zero RPM.

    I see just over 5 KPA pressure drop as an example. I find the pressure slope of the turbosmart 1200 to be very good, that's what I use. I would try a better quality fuel pressure regulator and rewire the fuel pump using a realy close to the pump with large gauge wiring.

    Hi agree that there is some space for improvements on Accel enrich. If you enrich enought that you don't see a lean spike at the begining of rappid TP change, AFR's goes usually to low. Even if you set decay rate to 100% and enrich only on one event. I can only explain that with fuel film which is built up during extra accel enrichment injection which is then sucked aways on the follow engine cycles, because flow goes up with RPM. Some kind of asynchron enrichment may help to built up a fuel film. Or a full fuel film modell.

    No spark on 350Z ECU in G35

    Well, I'd like to start off by saying sorry for being such a duma$$... Next, I'd like to thank those that worked with me finding things to try and get my car to run... It runs now... Apparently you can't FULLY trust an FSM, even straight from the manufacturer. I followed the directions for installing the cam sprockets, but the RevUp information is very limited... The images specifically tell you to install the exhaust cam gear 180 off. lol. So I did. After taking it all apart, I realized my error. Got it corrected, reassembled it all, then forgot one stupid hidden ground wire so I had no spark again. Fixed that, now she runs super smooth... Can't wait to get the burn in done and get on the road!

    I'll make a new wire and connect it to a new and good chassis ground and to "Plug C - PIN 8(Main Relay -)" and test it.

    TTLink with DSG - CAN bus data

    As far as I can see, the G4+ is capable of doing this with a user defined stream. I think the existing "load (abs)" parameter would be almost directly proportional to torque output so you could probably use this to create the torque message. I think you could then just use the CAN multiplier/divider/offset to convert the load parameter into the correct range of "torque numbers" that the gearbox expects to receive. I have a hunch however it might not actually want just predicted "torque output" - I vaguely remember seeing parameters more like "driver requested torque" associated with the few gear shift controls I have seen. - But I reckon even that should be possible to simulate with the existing tools. So the biggest challenge for the OP will be finding all the OEM CAN ID's and message structure etc and then finding someone who understands enough of it to translate it into the G4+ template and that will likely incur significant time and cost.
