Curious to what the forced induction guys are setting theirs at the respective load value.

around 11.5 to 1 afr at high load/rpm (high boost)....around 13-14 afr at lower loads/rpm (low boost)....... :jester:

I believe that is what mine is set at around 79% load. Just wanted to compare

Lee,

I did mine this way just to be safe and until I can get the motor broke in....
I do not think I will change it to much though as the engine seems to like it "A LOT"......:)

that's cool. I was just curious at what load values should I start richening the commanded a/f

Since your car will be more rpm based than what mine is I would datalog the rpm, load & boost and graph it to see how much boost you are running at certain load/rpms ...You will probably need to start about 50-60% load would be my best guess without actually looking at the car....

Mine is more load based so I have to start at about 2000 rpm and about 20-30% load......

Turbo's are just so cool............
