PE mode question When in PE mode, does the MAF come into play? What is the PCM actually using to calculate how much fuel it needs besides the VE table? I know it's not looking at the 02's....
I'm running a MAF and working on WOT tuning. Thanks for any info/advice.

Maf will cause the most change. HPT has a histogram. Log command and actual A/F ratio with MAF HZ. Make a filter that only logs when the a/fratio is below 13.75.

Thanks for the replies. So to get my VE table correct for PE mode, is it correct to say I need to adjust it in speed density mode and then re-enable and scale the maf?
