I have a question for you people with the 2.4L. Have you ever wondered about the alcohol maps? Are they fully functioning? Is this some early GM flex-fuel implementation? Was this GM taking into consideration that people may be using alcohol cooling on the GM supercharger? Or was it GM knowing that E85 was coming out soon, but never finished testing on E85 at the time?
Potentially could we set that alcohol map for E85 settings, would the PCM "think things through" between the alcohol maps and the regular maps for a happy medium when you're going from E85 to regular pump gas?
Thoughts, ideas, comments, questions, inquiries, genius commentary is welcome.
I'm going to be doing an E85 tune in the next month or two, and am curious about these (alcohol) maps.
