Thread: E85 tuning

    E85 tuning

    I am converting my mustang to run E85. I have enough fuel pump and injector to support the switch. From a tuning standpoint, can I just change the target stoic value in the tune or will I have to go through the MAF tables again and do more WOT tuning? I read up on this a while ago, but don't remember what the consensus was and can't find the thread I was referencing.

    Change stoich and make maf adjustments as needed. When I converted over stoich over to e85 I only needed minor maf adjustments.
