Alright, so after going in circles trying to tune my car with a NIStune ecu, I thought I'd consult the internet and see what you all had to say and see if anyone had a saved tune that I could bum. So here are the specs.

1995 S14:
- 99 silvia spec R SR20det w/ 6 speed
- NIStune type 4 board in ADM ECU w/ modified JDM wire harness
- Greddy Profec 2 spec b boost controller
- 555cc injectors
- Z32 MAF
- S15 stock turbo
- AEM wideband (runs crazy rich most of the time)
- anything else relevent?


Anywho. The thing runs rich (as previously stated). It usually hits the 11's and then drops into the 10's and below at 25% throttle or higher. If I'm cruising, it's usually in the 13-14 range and it'll occasionally jump into the red when giving it throttle from a dead stop. I also get a hickup at around 4k and occasionally it'll misfire past 4k at wide open. But I'm getting into too much detail here. Does anyone have a similar setup with a saved nistune doc. that runs well?

so you have a bone stock S15 with 555cc injectors and Z32 MAF?
