    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.

    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

    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.

    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.

    Im not sure if you are asking a question or making a statement? Of course the fuel table and ignition tables (and all other tables) will need to be tuned to your specific engine before it will run well. It sounds like you dont even have a good grasp of the basic fundamentals yet so Im reluctant to advise you touch it yet. I would not attempt to tune a turbo car with this level of understanding. I would suggest you start by doing something like the low cost EFI tuning fundamentals course here to get a better understanding of the theory behind it: https://www.hpacademy.com/courses/efi-tuning/ If you try to tune without a good understanding of the basic theories then it will just end in disappointment.

    What is wrong with my tune?

    I just had a quick look. There is some pretty odd stuff in there. It looks like it has been tuned for flex fuel but there is only one ignition map and no other corrections for ethanol content. Usually E85 can take a heap more advance than petrol so what fuel was that ignition table tuned for? VVT looks like the offsets are set incorrectly. The RH inlet cam is showing 10deg advance when it is in the fully home position. That means it will be getting 10Deg less than what is commanded. The VVT and ignition tables both have big "holes" in them around the cruise area that is going to make it drive pretty horrible. Boost control not working great at all. Fuel control is not great either. I would say this is due to there only being 1 VE table set up, which doesnt usually cover flex fuel well enough especially when injectors havent been flow tested on both fuels. I think the saving grace is you are running it on relatively high eth %, which is relatively forgiving. I wouldnt give it a hard time especially on petrol until it is looked at by someone more competent or interested. If you want to PM me the tuners name I will pass it on to the right people to consider.

    Another look show it's reducing boost target in higher gears but gear detection is not set up correctly. Your vechile speed is showing when in 0 gear.

    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

    Closed Loop fuel trims

    Yes, in the next 5.6.6 firmware the CLL trim has 2 fully configurable 3D tables, so you can have different limits for adding fuel than for subtracting fuel and have those limits mapped against MAP, RPM, or almost any other parameter you like. I dont think the release is far away.

    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.

    12v PWM Output

    The aux outputs have a pull up resistor to 12V, so they are 12V when "off" and ground when on. These can be directly connected to an aux out with nothing extra. As Richard says though, the logic may be inverted ie 0% = max flow 100% = min flow, I have set one up before but cant remember if they work that way or not. What is important though is they need a 3ms "wake up" pulse, so to do this you have a cell in one corner of your PWM table that it will always pass through during at startup (say 500RPM), then you can drop back to normal numbers after that. Use 150Hz frequency and 50%DC to give the 3ms. Read this for the min/max DC: https://www.tecomotive.com/download/PWMinfo_EN.pdf

    Trigger Errors - troubleshooting?

    Good to hear I'm not the only one ever to be confused with that. Even knowing to imagine another wave in the missing teeth gap makes my brain hurt. I can see it sometimes. That fixed it! Was 245deg and now -119deg offset (after a 4deg timing light adjustment). Trigger scope during idle looks good and NO TRIGGER ERRORS! Starts easy now, timing is steady, idle is good. Now we can actually start tuning. Thanks for your patience and odd hours troubleshooting! Log 2018-11-12 9;11;38 pm-idle.llg Trigger Scope Log 2018-11-12 9;08;33 pm-idle.llg

    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.

    Traction control with DBW

    E-throttle is generally too slow to be the primary torque reduction to control slip. I believe there are some ECU's that use DBW as part of the TC strategy but it gets far more complicated - basically they will still use a traditional fuel/ignition cut as the primary torque reduction to get the slip under control quickly, then only reduce throttle if the cut has to be applied for a sustained period of time. I have played with it a little before (you can put slip on one axis of your E-throttle target table if you want to experiment) but found it to be pretty useless. To reduce torque by say 20% with an ignition cut you only need to cut 2 out of every 10 sparks. To reduce torque by 20% using throttle only on a typical turbo car you need to close the throttle by something more like 50%. What's worse is if you suddenly regain traction you then have to move that throttle all the way open again and wait for the turbo to come back to speed before you have full torque recovery.

    turbo potentiometer

    As Simon mentioned, you will need to wire the output of the potentiometer to a spare analog input (with the other two pin on the pot wired to +5 Volts and sensor ground). AN Volt 4 is shown in the example below. Then select a spare Cal, I use 4 as it is a 2 point linear cal instead of a table. Next, in the cal settings choose % as the output unit. IT doesn't have to be %, you could leave it as 0-5 Volt raw. I would start with open loop boost control, as you will need to find out what duty cycle is required to achieve a particular boost target. In the wastegate %DC table, select the an volt input as the y axis and populate the table with the %DC required for each boost step required. In the example above I have used 50% duty cycle as maximum boost. That is the easy bit done! I would suggest looking at the help file for information about setting up boost control and when you are happy with the open loop mode, progress on to closed loop boost as this will give you more consistent boost levels which will be met and maintained by the closed loop algorithm. Regards, Richard.

    EGT Conditioner

    Hi Guys, EGT-K 2CH power consumption is ~2-3mA @ 12V. OUT ground is internally connected with IN ground. Sensors ground in your ECU is chassis ground with separate filtering for analog circuit - right? You can connect it in two ways: Using vehicle ground (chassis ground): - EGT-K OUT signal to Adc input in ECU - EGT-K OUT ground left floating - EGT-K VCC input to +IGNITION or +BAT - EGT-K GND input to -BAT or chassis ground. Using ecu sensor ground: - EGT-K OUT signal to Adc input in ECU - EGT-K OUT ground to ECU sensor ground - EGT-K VCC input to +IGNITION or +BAT - EGT-K GND input left floating Both cases will work. Second case will be more immune for external noise on ECU's power line. Hope it helps.

    G4+ xtreme ECU for sale brand new

    No it is not, they are shipped locked to prevent the ECU being used if it gets stolen etc. It will not work until it is unlocked. I suspect what Neil is getting at is he was worried if someone purchased it, it may not be able to be unlocked. You should contact the dealer you purchased it from and get the unlock code so that you can pass that on to the new owner.

    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

    Switched closed loop, G4 extreme.

    In firmware 5.6.6 we added 3D CLL trim tables. You get one table for adding fuel and a seperate table for removing fuel. So, you could turn these on, then put your switch status on one axis. In the example below, I have my CLL switch on DI4. I have put DI4 on the Y axis of the trim table (0 means switch is off, 1 means switch is on). So for instance when my switch is on and at 4000RPM the CLL is allowed to add up to 20% fuel. When the switch is off it is not allowed to add any. Obviously the other axis doesnt necessarily need to be RPM, TP or MAP might be more suitable but it is up to you.

For those who have installed a tablet with PCLink inside the car it would make more sense to be able to "simulate" switch actions from the software, rather than wiring and installing mechanical switches to do the same thing. I guess a generic approach where all digital inputs might be assigned to a "software user interface panel" would be worth considering. Just a suggestion to improve an otherwise very good system / software. Best regards, Florin

    How to setup mixture map

    Your mixture map is whatever your fuel table is. If you have two fuel tables, you need to go into the options and switch to that instead.

    PCLink Software Issues

    It's a graphics driver issue, fixed it for 5.6.6

    CAN to Dash on a plug in

    You will only have two wires soldered into the CANF plug as per the pic above, CAN H & CAN L. It will then not interrupt PC communication.

    Interpolate Extrapolate and Smooth.

    Yep, looks a bit extreme but it will be a safe starting point.

    12v PWM Output

    Aux 5 to 8 can high side drive to turn the pump on or off, although if you want to use a variable speed, and are using the Aux out as a GP PWM, 0% duty cycle will be 12 Volts and so turn your pump on and 100% duty cycle will output 0V and turn the pump off, just set your PWM table up with the temperature versus duty cycle axis upside down. HTH, Richard.

    R32 GTR issues

    Looking at the log file posted for the speed, there seems to be a frequency doubling artifact. This might be caused by a double edge on each transition causing the ECU to randomly see twice the frequency. possible issues could be compromised grounding (old loom with oxidised ground rings maybe?), a low pass RC filter might help. HTH, RIchard.

    Knock control and corrections

    HP Academy have a decent webinar on the subject. A USD$20 membership will give you access to their webinar library. https://www.hpacademy.com/previous-webinars/049-setting-up-knock-control-link-g4-vipec/

    Temp sensor inputs

    Yes you can, you just need to wire in a pullup resistor to 5v so that the AnVolt input sees between 0-5V depending on the resistance of the sensor.

    The 360 slot discs will usually work ok provided the mechanical drive system is in good condition in terms of backlash etc. Swap your trig 1/2 wires over and give it a try.

    The Expansion loom is an optional extra. http://dealers.linkecu.com/XSL_2 It plugs into a small socket on the PCB. On the BMW plug-in the expansion loom will give you 2 extra temperature inputs, 2 extra analog inputs, 2 extra digital inputs, a 5V supply and a sensor ground. The Spartan would connect to one of the volt inputs and the sensor ground.

    Link extreme and Dash 2 connection issue

    You might be better to connect the speed sensor to the ecu rather than the dash. From memory the Dash 2 only works with Hall effect speed sensors and I suspect the FD is reluctor. The ECU will accept either type and send speed to the dash over CAN
