I’ll have a pretty high compression ratio on the engine I’m building, so 92 or 93 will be my lower limit, I think.
RaceTrac has E85.

Cool, I’m excited to get this project done and get get it over to you for tuning. Should I reserve myself a spot for a couple of months from now?

A couple last (I think) questions:
Will this tune contour to “learn” on its own and get better over time, or does that require a more modern control unit?
What should I replace and/or check to make sure everything is working well prior to a tune, e.g. wide band O2 sensor, MAF sensor, etc.?

Can a Decipha tune also tune the transmission?
-Upshift/Downshift mapping
-Torque Converter lockup for each gear
-Line pressure adjustment for each gear
-Up-shift schedule

Can my stocker adjust for dual fuel, i.e. 93 to E85 and back w/ a Decipha tune?

It’s MAF.
I maybe should have mentioned that I’m moving from my stock 302 to a 408 or 427 stroker.
My goal is just a lot of torque for towing and off-road. I don’t need tons of HP because I never need to go much over 85 MPH, and I never take it over 5000 RPM. It’s mostly a daily driver, but it needs some “pep.”

Is it helpful/necessary to get an aftermarket ECU, like the subject product, for a Decipha tune, or is my stock ECU (95 Bronco, OBD 1) good?
