    I have seen some dual flash pcms. Google it and you will get what you are looking for. However, they have been know to have problems but still interesting concept. If you wanted to do it right just buy HP Tuners and flash the tunes as you need them.

    That would be interesting. E85 requires so much more fuel. Do the octain table offer fueling changes or just timing curves? I havnt seen the ability to change the fueling curve or I'd be looking into this also

    Or? How would running e85 effect a 93 tune? I've always just had Allen do a ferocious 93 tune on my trucks. Maybe I'll just keep it that way!
