Power Fc

[GTRAAH]

I have just modded my car R32 GTR 1994. New cams, new injectors, turbos, fuel pump,air flow metres, power Fc... etc My car just came out of the DYnos yesterday IS it a common problem when you get your car tuned that every so often you go to start the car its doesnt kick straight into perfect idle, sometimes it rumbles almost like its going to stall then goes up slowly to the correct idle & sometimes ive had to press throttle to help it kick into the idle, this morning seemed to start well not sure about tomorrow morning.But the strange thing is id leave my car off for about 1-2 hrs and thats when its been seeming to do it so far its been 2 days out of the dyno.

Yep, thats why people retain factory ecu or piggyback - nissan spent lots of time and money tuning that stuff

You can tune it out with you PFC

yeah my s15 power fc used to cause a very high idle like 2500 rpm untill the water temp hit 61 degrees and then it chilled out, on startup.

similarly sometimes if i pull up at the lights it would idle high then chill after a few seconds
