Both logs don't go to redline because I am seeing a few psi higher than my target levels. Due to that, I didn't want to rev it out too high just in case.
Looking at them I can see the IAM stays pretty constant at 0.7x. The AFR seems a little on the lean side too, but I'm not a tuner.
What do you guys think?
This is an off the shelf tune for a turbo car. My wastegate spring is 7.25psi and the high boost target should be 9psi. However, I usually see 9-10psi on the low map and 11-12psi on the high map. |
the reason your IAM advance multiplier is at 0.7 and below is due knock/detonation it should be one your getting a fair amount of FLKC on the low boost map and more on the high causing the IAM to drop more.
looks like you need to run better fuel or get your tuner to re-tweak a few things, looks like its going lean on the high boost map (12.75 afr ) and your getting more knock. looks kind of lean for a boosted car on petrol.
I'm not much good on boosted stuff but overboosting could probably cause that maybe wastegate issues
