I've searched for hours and called various shops and still can't find any information. How in the hell do you adjust the tps on a series 2 rb25det.

Bump

do you have an aftermarket ecu? stock tps or are you running a q45 tb? basically there is a nedle attached to the throttle plate that carries a 5v signal and a variable resistor to pick up the signal. i dont have the stock unit anymore but if you can rotate the tps this is the best youll get. if not from what i know there is no way to re calibrate it. its either good or not good. but if you have a plug and play or stand alone most will have tps sensor calibration settings within the software.
