The better E85 systems use a sensor which dynamically determines the exact gasoline:methanol ratio, and auto-tunes appropriately

Again, the map needs to be dynamic, not static.

My main concerns are mainly how to make sure Im running the correct octane for my E85 map and how I would go about switching between maps when I fill up. Should I hang my head in shame for not going the ProEfi route? Or will I be able to make E85 work with the AEM?

Thanks for the help!
I believe that the gasoline:ethanol sensor can work with the AEM v2.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
