Nistune Forums

Yeah I had a bit of a blonde moment haha.

Okay I really am not sure what is going on. I started from scratch; stock map, changed to z32 afm, and played with k constant (default value (at 100%) was quite high compared to last time) and managed to make it run, up and down the street pretty well, very slight hesitation and not over fuelling an...

+/- 10% would be expected maximum. This tune would be same as already on there. Something else doesnt seem right then. Check air leaks and perhaps try another Z32 MAF if possible If not try the ER34 MAF again with stock map in the ECU I don't have the factory maf, sold it already and to use another...

Sorry forgot to mention my ecu is ov812

Hey Matt will try that. You probably remember my ecu, you fixed my mates great soldering and retuned it with z32 afm change on it. Would this differ from what you are providing Me here? Also how much should the k const be adjusted. Tried again last night, at a low level it made no difference, at aro...

Yea mate definitely getting a reading.
Blew air through it using compressed air before installing and installed the right flow direction and nistune shows voltage change depending on airflow and throttle.

I'll explain what happens. Afm has been modified to z32. Car idles but doesn't accept throttle, just dies off. Change k constant (excessively) and it doesn't idle well but revs and dumps fuel, (lots of black smoke). Adjust it slightly and it makes no difference. I can't get into a tuner until next T...

Hey mate
That probably would have helped, stagea rb25det neo

Hey guys just got my car running after a full rebuild and put in a nistune with stock map, modified for the afm. However it starts but as soon as throttle is on it stalls. I believe I need to disable the o2 and adjust the k Constant. However I was wondering if anyone can confirm anything specific I ...
