I dont do boosted applications much and was asked to help with this, so here i am. Mostly i stick with Gen3 but am familiar with Gen 4 stuff, just nothing boosted. He does have a set of ID1000's but has not done the install because he was unsure of how to do injector data. Im not worried about doing that, ive done injector swaps before, but at the moment he is worried about this limp mode issue. Codes list is attached, along with tune that i recieved and one that i made a few small changes. Also a log file, which i know is basically junk since he was not looging anything that matters. I have told him to take the tune i altered and data log with channels VE, DYNAIR, INJ pw, Inj duty cycle and any torque based channels as well, any other suggestions? Waiting on a new log from him at the moment. Will post when i recieve it. Anything else you guys wanna know, just ask and ill get the info.
This is the message i got from him.
The problem I am having is that if I go WOT, the engine goes into LIMP mode. There were a couple times it didn't go into LIMP and it pulled like a beast. Going 50%-75% throttle power seems good, but WOT is where it falls on it's face and goes LIMP. Using 3BAR MAP Sensor with Linear and Offset to 312.5 and -11.25 respectively.
After hitting LIMP, I get a bunch of codes. I can clear them and all is good until I hit WOT again. Attached is list of codes.
