Nada?!
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!
fueling correction is made in the VE table. The high and low octane tables only change spark. If you ran e85 on a 93 tune you would be lean. E85 requires a lot more fuel than gasoline. They have different stochiometeric 14.7 gas vs. 10.5 (don't remember exact number for e85 but think 10.5 is close)
I think I remember reading 9.7 for e85?Quote:

Better to be rich than lean. For those who are unaware and may read this E85 is blended with more gas in the winter for easier cold starts. This means that it is not always truly E85.
What school?Quote:
