Evo 8 fuel at idle issue


Recommended Posts

Sorry if I'm blatantly missing something, I have an evo 8 I have previously tuned with no issues, however, I have recently upgraded injectors to RC1200 PL9-1200 from the 1000, used the recommended latencies to start. Also changed stock reg to a Aeromotive A1000 FPR, set to 3 bar, the bosch 044 has been swapped out like for like as suspect issues.

So the car idles at 0.75 lambda even setting idle area to 0 on the fuel map leans it to 0.8, no less, master number at 4, increasing it richens it up. 

Any input?

Thanks gents
