I own a Nissan Silvia S14 Zenki (with SR20DET Blacktop) from 1994,
I have done some tune-up’s on it, and when it was on the dyno for mapping, it was running god, but after the first real attempt with 1 bar of boost it made 340 hp at the wheels and all seem fine, but after around 10 min or so the idle went strange, when we tried to rev it, it made some strange thinks around 2200 rpm, so we looked at the maf, but when we touched the wiring it died, we found that the shield has touching another wire, but after we fixed it, it still goes wrong.
Video of the idle and around 2200rpm: https://www.youtube.com/watch?v=LahkSgcPyhA
And this indicator is turned on also:
The problems is gone if i run on stock ecu.
