    They don’t have a FF OS and they use narrow bands and not WB... so in that case not possible to REALLY make a FF tune... if you want to run e85 only, just set stoich to the e85 ratio

    There is no stoich setting on a JTEC PCM. It's not a VE based system. It's direct pulse width.
    If in doubt, multiply everything by 1.1.

    It's old school stuff. Just regular tuning. If you can tune it on gas you can tune it on E.

    That's a pretty open ended question and we are missing a lot of information, so probably not.
