Re: 2 maps on E85
Oh really.. I was wondering about how I could switch it.. how did u wire it.. I'm curious so I could have a idea on how to do it.. I was not going to fully have e85. On it meaning.. like at a qtr of a tank fill it up with e85.. cause i never let my gas go down all the way to empty..

There is a BIG difference in fuel consumption between gasoline and ethanol. If you start mixing gas and E85 you are going to change your ethanol to gas ratios and you're going to get really nasty fluctuation in your AFRs and instability with your engine being able to ward off detonation, especially if you mix E85 with a quarter tank of gas and then try to run the E85 map. You will be rich as hell and probably detonating everywhere.
If you're going to run different setups between gas and E85, you need to have as little left as possible when switching to the other fuel type.

That is a BAD idea.

i suppose you could use a fuel sensor, but it just seems like a waste of effort to me. its not really a big deal imo to drain the tank and put whatever fuel you wanted to in there.

I have a few different tunes that are saved on my laptop. All I do is upload the file to the ecu to switch to a different tune. The hardest part about it is booting up the laptop. lol.
