I cant say that its NOT the 3x2 thing you got going on, but i find that hard to beleive as i see the differential pressure drop even when car is not boosting yet. Down that low i doubt that the injectors are open long enough to drop pressure. Even if there are two of them. Cant help but think something must be fishy about the FPR hookup.. Old dirty (partially clogged) nipples on the FPR or plenum? Way of topic but i cant help but notice the car is suffering from timingscatter. you can see it on the slightly bumpy RPM line, but it is really obvious when looking at RPM rate. Its the red line that sits just below the RPM line. This is your log Here is a log from my car that has a trigger fitted at the harmonic damper. Logs looking like that should help pushing a few cranktrigger setups on to your customers... Sorry! Back on topic.

Looks weird Kristian. Could it be that the FPR is not seeing the full manifoldpressure? I meen a slight leak in the vacumline between the plenum and the FPR? Maybe it has a small crack or a slightly loose fit on one of the connections. You got a 0.1v drop on the pump between...? Alternator and pump? Whats the voltage at the pump? Edit: Looking again at the log i can se differential fuelpressure dropping through the whole log where map is climbing. To me this indicates that the FPR isnt seeing true manifold pressure. Where is it hooked up too? Edit again... I now see you checked out my suggestions allready.. Well, i`ll leave this up anyway.

Did you tune your main IGNITION MAP on a dyno? You speak of tuning Antilag and RPM limits and boost and what not but no word on actually tuning the important things? The PCL Dave provided you with is a BASE map form which you need to get the car propperly tuned before you start to mess with all the extra motorsport features.

Yeah charge reversion might be the case. The fuel is being dumped in there so it has to go somwhere. But then again. If it goes back into the intake again the charge should go even richer on the next cycle. Or at least there should be a rich dip AFTER the problemarea when the fuel goes where it should. ( Im just speculating here as i have never had such a problem to handle myself. So just thinking out loud) As it doesnt then maybe it actually gets blown out the exhaust because of to much overlap (?). Got access to a gas analyser? Could pick up a possibly high HC count. Really waiting for Dave to chime in again as i know he have done his share of RB`s

Weird. You should check timing through a run yes. Dont nessesarily think it got something to do with the problem , but i suspect you got some timing scatter happening there. Dont see VTC settings in the PCL, nor any AIT correction settings. Maybe im looking at a different version of teh program? 4.10? Well the fuel IS being dumped in there, the burn IS happening (no stumbeling), it IS going lean, and timing is ok (maybe!). How much extra fuel would you need to dump in to actually correct the reading? Could it be som e sort of charge reversion at just this point? Do you feel anything in the car att all? How big is that HP and TQ gain really? What kind of knock detection do you have on it? Looking closely (got the log on my 55" screen) i see a dip in the dRPM rate at the area of this happening... Im thinking you really should check that timing now and make sure its stable.

Im with D here. Need more logged parameters. Nothing to pick up on so far. Only thing i can see from a quick overview is that AIT fuel correction isnt enabled. I take it there is no VTC on this car?

-yes that will work, and it is the recomended one.

The numbers now used in the fuel tables represent volumetric efficiency . It is now VE based. Simplified this meens that if your 2 liter engine ingests 1 liter at a particular cell in your map you would have a number of 50 in that cell, as it ingests 50% of the potensial volume. This would be in a low load situation of your map. If you have a natural aspirated engine and open the throttle wide open on high revs you would theoreticaly be at around 100 in the cell. Now all of this of course depends on how good your engine actually breaths, and the fuel map will give you the answer of that when its fully tuned. Edit. Removed a part so that it doesnt confuse anyone..

Is this on a Cosworth actually? Be sure to pull the triggerwires away from the high voltage areas on the engine. You can use a regular plugwire between the coil and the plug to hook up a timinglight. You MAY have the trigger signal 360 degrees wrong. Not sure i get wheter you actually calibrated the timing or not, but thats one thing that obviously needs to be done.

Simon?

Yeah, a predefined CTC table is something that would make it easier. Actually thats what i would have expected with a feature like this. Now you have two unknowns with one result. Its a lottery to get the two unknowns right. Well Ash and/or Simon, you`re up!

Not really Dave. Appreciate the the effort though. Where/how do you start if you start building a map from scratch? Do you build a map the "regular" way with AIT comp and finish the fueltable first THEN turn of AITC and CTC on. Then try to get the AFR to match the target with the CTC table? Or is there another aproach to it?

It seem like a good option to have and i think i will try it out when i get my car back together. It will need a retune so i might just as well try CTC. However! How would you go about tuning it. Thinking about it i forsee ALOT of tail chasing trying to dial it in. As i see it if you dont have a good CTC you will not be able to dail in a good fueltable, but then again, if you dont have a good fueltable you wont be able to dail in CTC. As i read it the only temp CTC does not do anything is at 18 degrees so to avoid it seems impossible. Only way i can see is if you tune the fueltable with AIT correction and coolant temp correction first and THEN got to CTC. But then again this is double work and it wouldnt be perfect either. Im sure im missing something so please fill me in.

Got another one. Is it possible to implement a odometer functionality in the ecu? What i am really thinking about is a way to have the ecu flash a CEL sequence when key on after a preset number of kilometers driven. This would be used as a service/oil change reminder im my case.

He probably want to know how high he needs to span the maps. No point in spaning it up to 4 bars when you are only going to run 2. you would just loose resolution that way.. Yeah i think he is "only" a nice enthusiast.

Ah. That makes sense. Well i stand full heartedly behind you on the request of using chickens as a base!

For some reason you are both using Celsius for a MAP sensor... just saying

Yes you need to CAL table them. You cant put in a negative value cause they are absolute values. Mening that what you and i breathe in at sea level is 14.7 psi. Not 0. So your -14.7 should be set to 0. About your ait sensor Select a cal table Set input units to Ohms Output units to Celsius Output start table to -40 Increments to 10 Set theese values it the table at the different temps. (65000 at the -40, 45000 in the -30 and so on) 65000,45000,25000,16250,7500,5450,3400,2600,1800,1350,900,450,362,273,185,126 If Celcius isnt you cup of tea then convert to fit..

Well apart from a working CEL while ingition on (as i emailed you about) being able to read codes is a start. Imagine a tech come across a CEL, or somhow triggers one by accident himself, and when he hook up his reader he gets a "no codes" message he will start to wonder... Personaly i miss being able to have a read on EGT`s. (PID 78 and 79) Exhaust (back)pressure 73 Oil pressure As the latest isnt in the industy obd2 pid list one would have to be able to make our own parameters. Oilpressure as an example is one that in the Torque app is a predefined custom PID called 221470 But i kind of assume more parameters will be implemented as time passes?

Got it working! I somhow mixed up sensor ground and chassis ground on the obd connector. Waking up with a fresh head this morning made the trick. Set it up as 350z and its working. Its not sending out EGT data though. Got 2 hooked up to anV6 and 7 using caltables. Is this cause of the car i chose to mimic or is it just not implemented yet? Also torque does not pick up on faultcodes. I triggered my ECT fault settings and made a code in the ecu but the app did not pick up on it.. But as i understand it this feature is still under development so... Edit: found my own answer in a few helpfile pages i had not seen. Dont know how i missed it. It seems like that as of now EGT through CAN has not been implemented yet. Do this meen that you cant configure it manualy either?

Bringing this up again. I have now installed a obd2 reader on the can input. this one. http://www.plxdevices.com/product_info. ... 2BLUETOOTH well the V1 to be accurate. Im using the "Torque" app on my phone. Cant seem to get the adaptor to see the ecu. I tried to setup the CAN as both user defined and as different cars. like 350z. I figured that if the ecu mimics the canprotocol of the 350z the reader should be able to pick up on it. (although i dont actually have a 350 but the kiwi dont know that). As i am apparently doing it wrong, are you able to provide me with a few screenshots of how the ecu should be setup to get me going? I read the can part in the helpfile but that did not do much for me. I need to read up on CAN protocol i suppose. Again, this is on a i88! Not v88

One issue that I personaly came across is the one in the very first post here in the i88 section. The AC fan issue. Though i have rewired to work around it but still. Also as mentioned in that thread the AUX 9/10 status is marked red. As in not OK although it shows batteryvoltage and should show green/ok. As for 5/7 bar thingie. I have a mapsensor hooked uf for exhaust backpressure on ANV2. This is a 7 bar sensor but as i had a hunch, and the fact that i try to avoid using up all 6 calibration tables if i can, i choose "5 bar sensor" in the menu and bam! Dead on barometric pressure.. Will take you up on that testingprogram... Edit: That email is non existent.

First off. Not trying to nag but how is the new firmware coming along? Do you forsee it beeing released during this or the next half of 2014? 2015? Just curious as i undrestand it will be an extensive one. If you are rewriting the "whole" thing would it be too much to ask if you would make it possible to make every sensor input customisable? Right now all we have are the opportunity to use only 6 different "custom" sensors. If we are not lucky enough to find our sensor in the predefined dropdown meny that is, but lets face it that list is very short. Implement a clibrationtable on the page that appears when you select say ANV1/ANT1. All the other kids are allowed! Why cant i??? And for the love of god, get that 5 bar/ 7 bar mixup of yours fixed.

In the helpfile it is stated that this sensor are not suitable for trigger sensing. Got an example of a sensor that you recomend for triggers? Hall sensors that is.

Shit man! Thats heavy. Good to see you focus on other things than your condition. Thats probably good for you. Hope for a speedy recovery. Yeah im glad Simon was able to confirm my problem. I figured it had to be a firmware problem, so it should be an easy fix..
