I’m finally switching over to e85. I previously had a stock chip and injector combo I was running until my fuel pump and turbo went bad. I had pretty good success in dealing with the tt 5.7 chip as far as scanning, diagnosing problems, and tuning. Now that I am switching over to e85 is the tuning pretty much the same as pump gas (go as lean as possible until I see knock)? When turning up the boost what do I have to look out for on the powerlogger? What will make the car knock on e85?
