I'm been slowly trying to tune my car but I'm stumped now.
I can't figure out why my Evo MAF is choppy. I purchased another used MAF to see if that's what it was because I read that dying MAF's get choppy. But it didn't change anything.
Also what is with the boost spike?
The BoostEst isn't exactly accurate, I'm thinking due to my MAF calibration still being off. But its hard to get the AFRatioEst and my Wideband to line up when the MAF HZ is all over the place.
I've gotten the knock down a lot from where it was, but as you can see its still pulling timing.
I imported a A/F DA table Snowboarder714 did for another member with a similar set up to get my A/F ratio closer to 11.0:1. But I did not import the timing table due to the fact that he added timing and i figured I need to resolve the other issues first.
Is there anything else I'm totally missing or looks completely off?
This was all done on 93 oct.
Here are two 3rd gear pulls I did within a couple minutes of each other.
Thanks in advance.
