Idle A/F Ratio ?
What A/F ratio (voltage) should be seen at idle?
Mine is currently in the .89-.91 range and it seems to be running rather rich. The exhaust stinks like fuel and the car stubles a bit. I just put a new motor in and when I fired it up I had to pull some fuel out using the PFC to get it to idle anywhere near decent since the A/F was around .98.
now I have it idling fairly well but it still seems a bit rich to me.
Mods are:
Street ported motor
Power FC
Bosch fuel pump
550 primary 1300 seconary injectors
N-Tech DP
Mid Pipe
N1 Dual cat back
No emissions stuff
Simplified turbo control system
Once the engine is broken in it's going to the dyno, but untill then i would like to get the idle situation worked out.
