Awesome to see this! I can't wait to see what type of power gains you see from E85...and if the stock fuel system can support it

Did you have to add any hardware to the car for this to work? Or was this just a software upgrade in the ECU?

Too bad Chevy didn't make the C7 FlexFuel like so many of their other cars & trucks! How awesome would that be?

That's real low vacuum for idle. Is that typical for the LT1?

You are VERY observant! I actually had the #3 cylinder down, which we were chasing when that screen shot was taken. All is good now.

The flex fuel was good for 30HP with about 5* more timing on the 427 and that was E70since I had 93 in the car when we mixed it in. It's reading E76 now since my last fill. My next goal is to test it with a client's LT1 to see how his car does. Stay tuned

Does anybody know why it isn't? It seems like it would have been sensible since everything needed to support this is already in production at GM...

I read that they could not get the tune completed in time for production release. Not sure if that is true or not. if true, then you would expect it to be ready for the following year.
