Nistune Forums

Well Im going to try messing with the ignition system just for peace of mind. also since I have spare parts that are new. from the log's I have done, the TP, RPM, MAF, Injection % etc are all pretty linear during the issue.

I also want to add, I am currently running the PMAS MAF from this car, on MY car with nistune with no problems what so ever.

I have been dealing with this for a few months now, talking to Matt off and on, wondering if anyone else has seen this. idle, fine, accelerating, AFR's fine, hit 2200-2600 RPM or so and it just pegs lean AFR's, stumbles, adn I hear the turbo spooling, but not accelerating, until past the RPM point (...

look into a PMAS spec'd for a Z32 or a HPX MAF, designed for blow though, just have to do the 5V mod to the ecu, and recalibrate Nistune accordingly.
