So, did some logging at the base tune I was running on wasn't bad at all. This is basically just a LQ4 tune with 12.5% added to the MAF table above 5000 Hz. AFR is around 11.8-11.2 at WOT with 24-25 degrees of timing. Thought it was going to be real easy to get it dialed in at WOT, but the AutoVE doesn't seem to be accurate at all. I put it into SD mode, got several really nice logs (blew through 1/4 tank of gas) and the end result was an AFR in the mid 13s at WOT I set it up to run 12.8 at WOT in open loop. It seems like the BEN correction factor is overshooting the target AFR? How accurate have you found the autoVE to be?
I'm attaching some tunes/logs. First is the base tune along with a log for it. The next tune is the SD tune, basically just 12.5% added to the VE table along with 12.8 commanded AFR. The first log for that tune looked okay. Log3 is the result of 2 successive logs with autoVE BEN correction factors made to the VE table. End result was AFR in the 13s. ???
Thanks for any help.
