Just switched a friends car over to e85 (lsa swap on about 4.5 lbs) and before the cyl airmass was 1.2 ish now it reads a lot lower which caught me off guard because the timing was higher then expected. Tuned with MAF only, and the switch to e85 was the only change to the car. Stoich was changed in the tune and obviously we dialed in the fuel trims. What are your thoughts?
alright i see the correlation now, the maf lb/h in the maf output frequency table is significantly lower on the e85 tune, i have pe set to 1.2 and have been adjusting the maf output freq to obtain that a/f on the wideband.
