please forgive me for not knowing much about the flex fuel tune process and im sure if I did a little searching I could find this information however when you get your tunes from Lund do you run it with 91 or 93 first datalog and then switch to e85 and then datalog there and the car will adjust based on lambda and the stoich of the mixture or do you just load the tune and your good to throw whatever fuel you want and datalog just to check it and for adjustments if needed?
Thanks for the help!
