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:
Here.
And this indicator is turned on also:
I have the temporary sensor for the exhaust unplugged, but it do not turned off my indicator :/
Thinks i have tried:
- Other z32 maf's
- Read DTC error (0 found)
- I have seen Maf value was ok in Nistune
- Had oscilloscope on several sensors, and it seem fine (Of what we know)?
Could it be my ECU that is simply gone mad?
