Except for underhood temps raising operating temps of engine, I don't think it should matter. I feel that if you are going to be thrashing the engine between two different fuel supplies, why beat up on the whole car? I's rather just put it on an engine dyno.

not messed with E85 tuning too much, but unless you are buying your fuel from a race fuel supplier, at the gas station the e85 content will be all over the place. Plus when you switch do you have a easy way to drain the tank completely? Most of the guys I helped had a sensor like this which identifies the ethanol content, and a good ECM should be able to be set up to automatically adjust for fuel content, no need to do two different fuel maps. http://www.maxxtuning.eu/products/engine...ethanol-contenthttp://www.ecmtuning.com/wiki/ethanolsupport Flex-Fuel sensor, but I think only a few of the high end ECUs support the use? I plan to add the flex-fuel sensor to my Coronet with the FAST XFI 2.0, but haven't done it you, so not sure how it will work once installed. I'm using the GM sensor as pictured in the second link.
