I had my car running pretty good on 91 pump gas so I decided to try to set it up on a flex fuel tune. Made myself a little base map to start off on and threw 5 gallons of E85 into about a half tank of gas. Started up no problem and idle is sitting pretty much around 1 lambda. Odd thing is that according to my scanner it says im about 20% lean at idle and cruising around. The car drives pretty smooth minus a bit of surge at low rpm from time to time but I'll work that out a little later. This is my first time attempting a flex fuel tune and I've gone through everything I thought was relevant. I'll attach my tune and a log file from this afternoon. Do any of you guys see something amiss as I'm sure I've overlooked a few things or set something up incorrectly. Thanks for any helpMy gs 2bar (flex fuel).hptMy gs flex fuel 1(first drive).hpl
