Power fc using same load points
 

Hi guys,

Just wondering if any of you D I Y datalogit tuners can shine in here. I know its a different car, but someone might be able to give some input. R34GTR Z32 AFM's

The problem im having is the same cells are being used for many parts of driving.

For example, ill tune the revs in neutral perfect, then the same cells are used during cruise and they'll be now rich. 12.7afrs. Ill then tune the cruise to 14.5-14.7 target afr, get it all right, then the same cells are used between light throttle cruise shifts and be boggy and lean between changes, also neutral revving.

The only way I can get the car to drive nice is have cruise on the rich side, then neutral revving and between shifts is acceptable. but then you just waste fuel cruising in the low
12's. The problematic voltage range in 1.6v - 1.9v. Anyway around this???:(:(

Is your scale/offset properly setup for your map sensor along with the Map Reference table being set up.

Your symptoms point to the PFC not recognizing the difference between rpm changes and absolute pressure changes.
