I am trying to find out if anyone has been successful in tuning the ID2000 injectors using the ATR software from Cobb. I am currently having issues with the AF ratio on the banks reading the same. They are AT LEAST a point off. Also the A/F correction, STFT, and LTFTs are not showing them trying to correct. Please let me know! Thanks.

As I said in email, I don't know why this is happening. We have not altered how the fuel trims behave and I do not understand the fuel trim code, and I cannot see any difference between AccessTuner Pro and AccessTuner Race that would affect it. Tony mentioned that the affected vehicle he tried worked with the AC on. AMS and Forged report good results tuning for these injectors, I have looked at email logs of ID 2000 tuning and didn't like them, and from what I see would not attempt to tune a car with them.

It may be that the very low pulse widths affect some trim control, but I don't know how to find out/fix as I do not understand the fuel trim code and have not personally dealt with problems with it.

Sorry John, Joe asked me to post in here to see if others had recommendations. Was just listening to him and didnt mean anything by it. Thanks for the reply and the help you have given me. I have a few things I am going to try... Probably throwing a FPR on it to ry and help.

No worries, just wish I had the answer. OEM ECUs can be pigs and these ones have much strange logic in them. I always wondered about finding the outputs and then writing something from scratch. Sort of a standalone software using the hardware of an OEM ECU, but it is too big a job to be viable except for small things like boost control where we do this.
