Have something weird on my own car. 2000rpm 50kpa.
One day VE is lean next day it's rich.

Modified 304 blue too injectors factory pump and reg.
Never been able to narrow down where the variation comes from.
Possibly the reg?

weather is the biggest contributer hence closed loop BLM's that change every day but not generally at one rpm range could well just be injection pulsewidth correction out for a certian pulsewidth
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

Was pretty tight at that rpm maybe 1800 2000 40 50 kpa. I just lived with it wasn't much in it maybe. 5 afr.
Whole table was very close. It's in the 12P custom thread VR288 think it called.

mine are rock steady regardless of weather. only place it varies a little is idle AFRs. not much, probably only 0.2-0.5 AFR from day to day. As soon as its off idle is virtually perfect everywhere.

I got my injectors done by The1 so i have it all calibrated.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.

Anyone here use an IAT sensor? Those tables help adjust fuel flow based on air temps.
