    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.

    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.

    First step will be to get the PC link tuning software connected to check what the MAP sensor is reading at key on engine not running. Fault 10 and 11 both relate to AN volt 1. It is indicating its at either ground or 5V it cant be both at the same time so there might be a setting issue.

    Boost solenoid valve advice

    Confession time: the hose I thought was going to the wastegate was going to compressor and the other way around I switched them around and now target boost seems to come around 25 % wastegate and controllable. I'm sorry to have wasted your time and to have driven the car in overboost dozens of times while trying to understand what's going on.... unfortunately I was just too sure of how those hoses were connected and I thought of any other complicated explanation but this. So car pulls strong and it seems that soon the tuning will be done. Next priority is getting the cold start decent but I'll meet you in other topics about that Thank you for your help and good luck!

    Fuel level

    Its usually a variable resistance sender. Should be able to use just about anything and feed it in on a spare AN input. Will need a pull up resistor between the signal and 5v reference as most are 2 wire. Then just see what it does outside the tank and create a calibration based on that. Most older units are not going to be a linear calibration so you will want to check multiple points from empty to full. Outside of that it should be relatively easy to get it on the CAN bus and on its way to the dash.

    You don’t need to change anything, the factory sensor works fine. If you do want to change to a sensor with isolated ground (2 wire) then the easiest option is to connect the 2nd pin to the shield and use that as it’s ground. For the boost solenoid, connect to factory wires.

    Possible bug in Thermistor Calc?

    The problem is the ecu uses linear interpolation between the cells in any table, yet a thermistor is highly non linear. Since you have such a big gap between the 24°C and 94°C cal points it will be very noticeable. The reason you see difference between voltage Vs ohms cal is because the voltage divider calculation will inverse the non-linearity affect (I suspect the voltage cal will be closer to reality than the ohms in this case). You typically want no more than 10°C break points for a thermistor cal. Pic at the bottom to show the effect, straight lines are your cal, pink line is more like how the sensor would behave. I would suggest you try the pre-defined Hella 6PT calibration as that looks like it matches your sensor reasonably well.

    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.

    It is not possible to decode them all since they are sent as bit fields. The stream below will give you the common errors for Lambda 1 using the CAN DIG inputs (you can view these on the runtimes screen). Set it up with ID 431, extended format. CAN DIG 1 will indicate "AFR1 Ready" CAN DIG 2 will indicate "AFR 1 Heater open Error" CAN DIG 3 will indicate "AFR 1 VM Error" and so on down the list. The LED's on the device give pretty much the same information so Im not sure how useful it is. AEM Errors ID431.lcs

    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.

    programmable logic

    I've currently got all 6 seven segments and the 8x8 Matrix to work with Link "generic dash" can bus output. There is some work to do with my neopixel library conflicting another of my libraries, and a weird issue with my can bus adapter only picking up frame 0 or 1 when you start to introduce a delay (like writing to the 7 Segs). However given a correction of my frame issue I'm not seeing any problems with refresh from the Nano. Weird thing is the Nano will do several hundred main loops prior to picking yet another frame 0 from the buffer. Although there is a deep imprint of my keyboard in my forehead I'm enjoying battling with the cheap ahrse and very flashy intelligent 7 Segs, 8x8 and neopixels... the cheap can bus adapter... not so much.

    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.

    R&D question - cylinder deactivation?

    But you also need to hold the exhaust valves open on the deactivated cylinders otherwise you just have massive pumping losses. So not only do you need the mechanisim to do this but you also need an engine like a hemi where there is enough piston to valve clearance for the piston to travel past TDC with the exhaust valves fully open.

    Boost Control

    Regarding your last answer Adam, maybe you could add the feature of switching map tables (or other inputs) from the user interface to the wish list? 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

    G4 plus PnP GTR34 hks v cam

    Many people with performance GTR's dont use the fuel pump speed controller so that means aux 1 and 2 are available. But if you want to keep the fuel pump controller then my suggestion would be to move the AC clutch and AC request wires to aux 11 and D9 on the expansion connector so that frees up Aux 3 and DI4 for the VCam.

    No Brianer, the Link CAN Lambda as we have the ability to see the controller status of the sensor, plus the ECU can extend the life of the sensor by many fold due to starting and stopping the heater at the correct times.

    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.

    Was this problem solved at the end? I am having the exact issue with Link G4+ plug ins on my FD. "When AC pressure switch(in series w AC button) is open due to high pressure, voltage @ pin 4V is 0v=gnd. This means that Vipec ECU does not understand that AC systempressure is to high and just keeps running the AC compressor. " Once the AC pressure switch 'clicks', I no longer able to turn off AC compressor, it will stay on. It's like the pressure switch is working the opposite way as it suppose to be.

    I will give some comments. The Link CAN Lambda was designed specifically to work with our ECU, it has bi-directional communication so not only is data received from the device but the ECU also sends data to it. This allows the proper warm-up strategy to be applied during start up, EMAP compensation can be applied correctly for situations where there is back pressure and if a sensor is reporting an error condition the ecu can disable CLL or in the case of multiple sensors, ignore the failed one from "lambda average" calculations. The stuff like temperature, heater voltage, etc are mostly only used for diagnostics. Most of the 3rd party devices will have no receive - they only transmit data so they dont know if the engine is running or how long it has been running for to apply the correct warm-up strategy (potentially shorter sensor life). Many of the 3rd party devices will send some sort of error or status message but in many cases it is not in the format that our ecu needs it to be able to do stuff like disable CLL. In some cases you will be able to log these errors but unlikely act upon them. I have used a few of the X-series AEM's on budget installs and they have worked ok for me to date but I do hear/see some reports of short sensor life with them more often than others. To get the extreme response speed they certainly dont use a Bosch chipset or control the sensor in the way Bosch designed it to be so sensor life is possibly a side effect that. Some claim they are not using a genuine Bosch sensor either. Yes, an ecu controlled relay is a good idea. It still wont give the proper heat up strategy but it is better than nothing. No. Free-air cal is not particularly useful in my opinion, it was something made famous by Innovate as they didnt use the Bosch fitted calibration resistor. Air has about 21% O2, exhaust gas has none when less than 1 Lambda. So it only calibrates on the lean side of the curve and even then it is like trying to calibrate your precision 1volt voltmeter using a 2000V source... Ecotrons ones have a good reputation - I have never used one myself but only ever hear good comments about them. If you are not in a big hurry I know 14point7 are releasing a CAN bus "Spartan 3" soon, I tested a prototype a while ago. I use his analog ones for most of my budget installs and have very good success with them.

    tps signal disabled when car running

    It looks like you havent run a TPS calibration. Here is the voltage being seen by the TPS input in you "no tps" log. Its changing just fine, assuming you only went to 20% ish throrottle.Your TPS % reads 0 the whole time, but that is because the calibtration is off. It is currently set to 0% = 1.315v, so anything under this voltage shows as 0%. Your actual 0% voltage is around 0.48V so the first 1/3 or so of your TPS movement isnt showing up. Now here is the TPS% vs the AN volt3 input from your "yes tps" log. Notice that the TPS% doesnt move until you hit 1.3V or so, but the voltage itself (and the real TPS angle) has moved quite a lot already. Turn ignition on, then go to ECU Controls menu -> TPS calibrate. This should fix it up. Once you've run this, check that your TPS% angle registers all the way from 0% to 99%+ and that the percentages line up with how much you are actually pressing the throttle.

    Ecu hold power

    Thats not really the idea behind hold power. Its supposed to be so you can reset idle solenoids and the like back to zero position. Trying to use it to avoid something like this runs a big risk that if you crank it for too long, the hold power timer expires, and the ECU turns off while its still cranking and you probably wouldnt even notice. Better bet would be to re-wire your key output in this case so that the main relay is triggered by IGN1 key pos *and* by start key pos (ie run a wire from the key start position output to the main relay trigger). Are you sure your ignition circuit drops out entirely when key is at start pos? Ive heard of accessory power dropping out, and in some cases there are 2 IGN feeds off the key and 1 will drop out (for heater, aircon, wipers etc), but in most cases where people think they have this behaviour its actually just voltage drop due to the load being drawn by the starter.

    4age 20v + Atom

    So those coils have built-in ignitors. I havent used these coils before but the pic below found online. Pin 1 is the trigger wire as explained above. Pin 2 is ground which should ideally be connected to a clean point on the cylinder head (not manifold etc). Pin 3 is +12V, this should come from a relay that switches on and off with the ignition switch.

    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...

    Idle Speed control motors - How to

    No, I dont see any way you will be able to get a DC servo motor to control idle air with our ECU. Most engines I do are ITB and I dont bother with any idle valve. Typically you can get pretty decent idle control just using ignition only. Set it up so normal warm idle uses quite retarded ignition (say about 0), that means the throttle blade needs to be set open quite a way to achieve a normal idle speed. Set up the idle ignition table with ECT on one axis so that when its cold it runs about 20deg more timing than when hot. Thats usually enough to get it to cold idle own its own with no driver input.

    Boost control. Under no load

    A base map is there to start the engine to allow it to be tuned. Which it seems did apply here ? Trying to copy other peoples maps in the hope they might do something for you, is dangerous. Have the engine tuned properly by a competent person otherwise you risk damage.

    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?

    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.

    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.

    3uz throttle map

    look up the wikipedia article for PID tuning. There is a gif on the page about half way down that changes to show the effect of increasing P, I and D values. Very roughly, P is how quickly it reacts (how quickly it applies motor current), I is the aggressiveness (how much current it applies), and D is like a smoothing filter. None of these descriptions is technically correct but it can be a lot easier to understand to this way than fully understanding the maths behind it. I had noticed that your TPS response was a bit slow in general compared to your AP - about 200-250ms, which has got to be noticeable when driving. Here's the process i've used to tweak ethrottle PID's in the past (in case the 1uz settings dont give you the feel you want, or you just want to understand "why" a bit better): without the engine running, set "run mode when stalled" to "run throttle" set your ethrottle target table so AP0% = TPS20%, then interpolate up to AP100% = TPS80%. ie your TPS will only span between 20% and 80% open with full accel pedal travel. probably store the ECU config at this point. It gives you a safe point to return to if you have to cut power a abort testing later on. go to the logging window in pclink, start a log, and make APS main and TPS main the only 2 parameters visible (or at least the only 2 in one of the groups) press the accel pedal slowly a few times then quickly a few times, then quickly but only to 1/2 or 1/4 pedal travel and notice how much delay you see between the AP line and the TP line. now go to the ethrottle PID numbers and bump up P by 1 and repeat the tests. What you are looking for is minimal delay between the AP line moving and the TP line starting to follow it. At this stage dont worry about overshoot too much, just bump it up towards 8 or 9 until you stop seeing much improvement. dont go past 9 though. Make some notes as you go about what numbers you are testing. If you get the throttle to the point its just oscillating and wont stop after a second or 2, turn the ignition off, start again at slightly less aggressive numbers. Now you basically play D off against I. D you increase or decrease by 1 or 2 points at a time. I by 0.02 or so. If the TP response looks "lazy" - ie its heading towards the AP line but starts to taper off before catching up to it (so TP gets to within 1-2% of AP and the takes a second to get the last bit), lower D until that tapering off point is really close to the AP line. If you see the TP line overshoot the AP line and oscilate a few times before settling down or if it doesnt stop oscillating at all, increase D until you only have no overshoot or maybe a single small overshoot then it stablises at the AP line. To evaluate I, looks at whether the angle of the TP line matches that of the AP line when you press the pedal. If TP isnt a sharp enough angle, ie its heading in the right direction but not steeply enough, increase I (by a tiny bit). If TP likes to overshoot the target/AP by more than a couple percentage points, then lower I a bit. Note: this is why you tweaked the throttle target table to between 20 and 80 - you cant normally see overshoot below 0 or above 100. You'll likely see overshoot worst when making large quick changes, and you'll see lazy response worse when making small slow changes. When you have numbers you are happy with, put the throttle target table back to its normal values and save everything. Regarding the APS and TPS calibration failures, you can do this manually by hooking up all 4x sensors but leaving your existing voltage values in place, setting ethtrottle to "quiet mode" mode, and pull off your intake pipe so you can manually move the throttle blade. start a log, then press the pedal all the way down, hold it for a couple seconds, then release for a couple seconds. repeat 2 or 3 times. Now push the throttl blade all the way open and hold it, then all the way shut (you need to press it shut, they like to sit at 3-4% when left alone), repeat a couple times. Now add parameters to your log view for AN 1, 5, 6, 7 - these are the raw voltages from the APS and TPS sensors. have a look at the min and max values for each sensor and enter these manually into the APS and TPS calibration screens. Also note if either of the SUB sensors doesnt have a full range of travel (ie it flatlines above 70% or something), you need to enter the main% value when the sub% stops increasing if this happens too. You should now be able to switch to "run when stalled" throttle mode and run another log, but this time look at APS main, sub, TPS main, sub, and you should see all 4 tracking between 0 and 100% together (subject to a littel bit of latency in the TP numbers depending on how well your PID's are tuned).

    DBW throttle on link g4+ celica st205

    If you are prepared to send it back to NZ, it can be modified by adding a couple of wire links to give you E-Throttle capability. We can also give you instructions to get it modified locally but you will lose your warranty if not performed by us.

    AUDI TT '99 ABS ASR LIGHT ON

    Hi If you swap back to the factory ECU do you have faults showing as the 99 model is what our test car was so would expect it is well sorted. Are you able to post or Email in a copy of the set up so we can confirm the CAN is happy.
