    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.

    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

    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.

    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.

    Engine protection question

    Note you can also make your main RPM limit table 3D to add extra parameters. Fuel pressure protection for instance if you use Differential pressure it should be relatively constant under all conditions so you dont need a full 3D table - you could just put it on one axis of the RPM limit table.

    Hey, I think this might have been suggested before. But once you start to understand the wall wetting concept, it starts to explain a lot of other concepts which are described seperately in the current software. Example - accel enrichment compensates for changes in wall wetting, but in a fairly crude manner. Cold start cranking enrichment is essentially compensating for fuel film build up over the initial cranking period on a cold engine, and the long time period of "tau" on a cold motor. Fuel cut on decel doesnt really go into this, but if there was awareness of the fuel film depleting during this period then "accel enrichment" would naturally increase again after decel fuel cut. It feels like if this was modelled many of the other enrichment features etc could be done away with or minimised. Here's a great article on it. http://www.megamanual.com/ms2/xtau.htm

    MX5 Fuel pump always on

    closing this out for the last time! for MX5 NA 1989 1.6 I got a heap of those connectors from Mouser. I rewired fuel pump to be on Aux 5. I wired the purge solenoid back up to Aux 7 and now use the purge solenoid as a cold start air device - small air filter on one opening, other to the inlet manifold, and solenoid activated below 40C. works a treat! also had the separate questions around the AF gauge and where to tap the 12V feed from to only be on when engine is running. Wanted this as when downloading big ECU logs, or fiddling with link, the ECU needs to be on for a while but not engine running, which meant in the old configuration, the AF sensor heater was also on - not good for longevity. Turns out the correct wire is the Blue/Red on the fuel pump relay (yellow re;ay and connector) up above the accelerator. hope this helps someone else in future!

    I always tune RB26's with TPS as the main fuel load table. I even use it as the main load on the ignition table with a 4d map for boost correction. I find it makes them much snappier. You are getting fairly low in the injector pulsewidth at idle. It is possible that the dynamics of your particular injectors are not consistent enough at that low of a pulsewidth. You could try to change the 1000 rpm cell at 5.8 psi in your Target AF table to 13.8 or so. If its a low pulsewidth issue this may stabilize it a bit. It seems to be maintaining idle fairly well in the log. Blaine Carmena Carmena Performance

    G4+ subaru wrx V7-10 plugin is a dud

    Wildwestaussi1 think best is if you just leave this forum. A forum is there to help out each other. Only thing you are doing is blaming products and other tuners. If you are incompetend to install and setup such a highend ECU, just don't touch anything and take the car to one of the LINK ECU Tuners you can find on the website. And before you are calling everyone an idiot; I'm a professional Tuner and worked with LINK ECU's on Subaru's for several years. I came never across such a problem you descripted. As you statet, there was alot going on with this engine/car before you have got your hands on. So go and search there for a fault, but don't blame a great ECU manufacturer!

    Toyota 1zz-fe base map

    The Dash Cluster temp meter is fed direct from the ECU, it will always read cold with every aftermarket ECU apart from Kaizen Garage's ZZE/ZZT Adaptronic based plugin which has an additional circuit onboard to convert the signal to one the cluster can accept. The stock ECU outputs it's engine coolant temperature signal for the dash cluster from pin B-17, on the 22 pin ECU plug. PCB pin THWO. You can trace the signal with an oscilloscope using the stock ECU from dead cold to operating temp and then use an audrino or similar to create a module that will convert one of the vipec outputs to a signal the same as stock the cluster can interpret The narrowband sensor is quite useless, please replace it with a wideband setup You will need to tune all the idle base position tables etc from scratch

    AEM MAP and IAT Sensor

    Hi, I haven't forgot about this project. I have been very unwell with extreme pain for the last couple of weeks. I am on large doses of very powerful pain medication, so my brain doesn't work correctly while under the influence and it makes me sleep a lot. I have just come back from the doctors again for different medication again, tonight. I have been working on the PCL file for this along with a few other jobs. I needed to know how much boost he wants to run for many reasons, boost cuts, boost control target tables etc, working out what his final fuel pressure will be with static pressure plus full boost pressure etc. Spanning the Y axis on Fuel and Ignition tables and any other tables that will be MAP,MGP etc based AXIS. The more information I can gather the easier it is to set things up. Setting up PCL files for cars that aren't in front of you is quite difficult hence for the many questions. Yes , you are all correct, I DO NOT WORK FOR ViPEC. I enjoy helping others where possible. When I first started I could only ask a random question here or there, I didn't have the luxury of FORUMS or the Internet for help. 99% of what I know I have taught myself through testing , reading and studying etc. It is something you never stop learning. I have been doing this stuff for close to 20 years and there is still so much more to learn, I had many frustrating times trying to sort out issues etc. This is why I try to HELP where possible. I also strongly believe in the product and love it's capabilities. Sure there maybe some things people wish for that aren't possible in earlier versions etc. But for a very fairly priced ECU it sure is loaded with some very impressive features. There are also many ways to control devices under certain operating conditions etc. So by getting involved and helping those out seeking help, I in return learn as well. No one has ever done everything. So having a go at everything that crosses your path will expand your knowledge base 10 fold. So in the process of helping you, at times I am learning also. That is what this FORUM is about, NO BULL$%@T, just cold hard facts and many suggestions to help you all in the long run. Regards Dave.

    Cam Position Parameter Lag

    I think the problem probably is you due to not using a compatible trigger & VVT mode. Your Inlet LH error counter is continuously counting up and the Inlet LH signal is reporting extra pulses. Try setting trigger mode to M52 VVT and VVT mode to M52, this should work with the single tooth cam and 60-2 crank. Trigger offset and VVT offset may need to be set again with this change. If that doesnt help please post another log and the tune file. I suspect something is also mechanically wrong if this is the case, in my experience the 2 state vanos is usually near instant switching (less than 50ms at a guess), you dont normally need to consider cam position at all, usually just switch VE tables at the same time the vanos is activated.

    Hi all, Bit of an odd one, just wanted to ask how best to limit the torque output via the engine mapping, the basis of this question is owing to the torque limit on my transmission - basically looking to limit peak torque in certain scenarios. I will be getting my forged engine fully mapped on a rolling road but just wanted to ask the question now. Basically my forged engine will have the capacity to have a higher torque output than my upgraded gearbox is rated to, I know that my gearbox can cope with slightly more than its rated torque but am looking at how to limit peak torque when needed - a bit like an engine rev limiter. I am guessing I should be able to limit the torque by pulling timing out in certain cells at certain boost levels using a 3D table? Eg: 7 psi - no adjustment 14 psi - no adjustment 21 psi - some adjustment 28 psi - more adjustment For my build, here are my limits (to give everyone an idea): 1.8 Litre engine Forged rods and pistons (9.5:1 compression) Supertech valvetrain rated to 8,500rpm CSS strengthened block able to cope with around 600bhp Stock gearbox with upgraded 3rd and 4th gears - rated to 295ft/lbs although have chatted to someone who ran 365 ft/lbs through them Now, a stock engine with a low boost turbo (7psi) makes around 220 bhp and 185 ft/lb torque, and probably around 250bhp and 200ft/lbs at 12 psi, have seen figures for a forged engine making around 420bhp and the 365 ft/lbs at 35 psi on a GT3071 turbo, I am looking at an EFR 6758 for my build which should flow well at lower boost but not run out of legs at the top end. Is anyone able to guesstimate the sort of torque I should be expecting? I think I should be ok with a bar of boost in terms of torque but anything more I think I might need to run a limit of some sort to keep it around the 300ft/lb mark - basically looking to make the most power I can (as the rest of the engine can make it). I have also seen these engine make around 500bhp at 7,500 rpm and 28psi on a 6262 but the peak torque is probably at around 460 ft/lbs - tad much! Plan for my build is an 11 second 1/4 mile car but daily driven - plan to run full power at the drag strip then drop boost pressure to a lot lower for the road - basically looking to make sure that the gearbox holds ok for the couple of drag runs to prove it can run the time but then turn it down at all other times. Sorry - was a bit of a long post but was just wondering what everyone suggests.

    Higher voltage on Aux 9/10 supply

    Bumping this to provide an update. The car is back together now (after some cylinder head woes). We removed four of the six throttle return springs and re set all the throttle plates. It idles nicely with fully closed throttles at 850RPM with 15 degrees of timing. The e-throttle response is much better. It's still not great, but seems to be acceptable. I did some testing with retarded ignition timing before pulling the springs and I wasn't happy with the resultant exhaust gas temperature. The idle base DC table is set to 3D and uses AP(main) as the secondary axis. This allows tip-in to be smoothed out by feeding in air via the idle motor at low pedal angles.

    The MAP sensor is only indicating pressure on one side of the butterfly though - My thinking is since these have a crankshaft driven supercharger and RPM is still high, even with the dump valve open there is likely a large pressure difference inside vs outside the butterfly. I have seen a similar but opposite effect when trying to open the throttle. Some BMW's have butterfly shaft slightly offset from center, so on those if you let them close too much when returning to idle they are sucked shut so hard you cant even move it with a screwdriver or similar.

    I know of some people that have done this but it’s not a good option in my opinion. Having two separate ecu’s controlling things with no communication between them and little understanding of how the oem ecu controls things is bringing a lot of risk to the party. For instance if the oem ecu cuts fuel as a limiter but your port injectors are still squirting you are probably going to melt parts quickly. With port/DI combos there are many other scenarios where the timing difference between the two injection events can cause very lean cycles also. Fair enough if it’s a junk yard engine with not much value and you are prepared to learn by breaking things...

    Tuning Considerations

    Yes, the same setting is available in two different places, you only need to adjust one and the other will change at the same time. It depends if you are using open loop or closed loop. If using open loop the base position table tells the idle valve how far open to be, the idle target table has no effect. In open loop mode the idle target table is only used for idle ignition control. In closed loop mode the base position table is the starting position that the idle valve jumps to when idle conditions are first met, then the closed loop control will take over and adjust the valve position further if needed to make the RPM match the idle target. The idea is the base position table can quickly get the idle valve somewhere close to where it needs to be then the closed loop only needs to make small corrections. There are instructions in the help file how to tune idle control. I suggest you start in open loop mode to build a good base position table. Follow this page in help: G4+ ECU Tuning Functions > Idle Speed Control >Open Loop ISC. Are you seeing this drift when the "set base timing" screen is open (so timing is locked)? What ECU do you have?

    Idle control needs work.

    Happy to help. Another suggestion is to use an auxiliary/fuel/ignition output to trigger a fix amount of air bleed using a solenoid. Then use a timer on this output. So when you shift though the gears the neutral step is not added as its no longer required or only now very small. You could then use the 3d idle ignition for the power steering idle up.

    The ecu is not entering idle control or idle ignition control because the base position table is commanding the valve open too far so the engine settles above the RPM lockout. Change all the settings in red below to match this example. It will likely still not work correctly but hopefully will be getting closer and we may get some more useful data from a log. Do another log for us with these settings.

    Hi all, a very big hurdle as far as the use of the very much preferred NTK sensor is simply the availability of the information as far as the software and the code to write the software to the NTK control chip. This information is simply not available to who ever asks for it making it virtually impossible to write to the hardware chip that the NTK sensor is controlled with. I have used lots of different brands of wideband meters for many many years and have had my share of sensor failures, mine are more so just plain worn out, use of leaded fuels such as avgas, Excessively rich mixtures on a hot sensor that destroys them as they get cold shock when very hot. Dropping them, melted wires, and the biggest one the unknown, loan it out , used to work, get it back doesn't work anymore. Letting the battery run flat with the sensor hooked up. Lots of things will destroy these sensors and or shorten there life span, incorrect angle in exhaust allowing H2O to come into contact with the heated element causing failure. As we all know H2O is a by product of the combustion process and can not be eliminated. So unless you have millions of dollars to get the chips coded and a full reconfiguration of the main ECU or another CAN MODULE i doubt we will see much happen here. The best advice i can offer is to avoid the above mentioned sensor killers. Calibrate your meter regulary, avoid over rich mixtures. Poor tuning of engines that cruise at 11:1 instead of stoich or a little leaner if possible will save the sensor life also. Also in this day and age, is that really a genuine, LSU 4.2 or LSU 4.9 sensor. The other issue is if the sensor is connected to a controller then an analogue output voltage from the module to the ECU is not of high standard, the sensor may be fine and the meter is the culprit. And this is where we come full circle back to the Innovate LM-1 with no analogue volt output earth/sensor ground. Earth looping. This issue was big enough for Innovate many many years ago to design and build a GIA, GROUND ISOLATION AMPLIFIER to stop ground loop feed back effecting readings. There are wideband meters on the market running NTK sensors, with the intellect (i definatly don't have it) and the ability to buy the chips,maybe the code could be reverse engineered to get the base code to program the chip, who knows. Anyway just my long 2 cents worth. Regards Dave. P.S BY THE WAY DAMIEN KING THIS IS YOURS HA HA HA HA, SHOULD BE THERE SOON.

    3ur-fe tundra 5.7 injector problems

    Depending on the age of the Atom it could be one of the early units that did have injector drives more prone to failure. But generally when the drives failed they wend to a short to ground causing the injector to be stuck on. I would certainly confirm all the loom is 100%. Swapping over to the second ECU will be a big step to proving this. Just make sure there is no short to 12V on that drive before connecting the replacement unit.

    Mainly due to the time involved in the development of the unit for the specific application, (working out pinout, making board fit factory case etc) Any temp sensor can be used but if you stick to the ones we offer the set up is easier. The Bosch sensor is the best but not so easy to mount. Any wideband controller with a 0-5V out put can be used.

    With the CAN being configurable I'm 99% sure it will be compatible and in the past Plex have been very good at working with our products so suspect thay will have worked in with the generic dash stream.

    Hi Davidv, I am just suggesting what I do in alot of my applications, solid lifters, forged pistons etc. You can go to 8000 rpm if you wish, however I would much prefer to use audible det gear and trust the human ear via electronics and then setup the ignition timing from there. Regards Dave.
