[QUOTE="KrisR, post: 13677733, member: 151707"] I do it all the time in my Coyote car. The Coyotes are always in closed loop and the fuel trims can take care of adding enough fuel if you put 2-3 gallons of E85 in to bump up the octane. Now obviously your Cobra (and most other cars) is in open loop at WOT so your WOT fueling will lean out a little. Depending on how rich it is currently tuned to, the E85 splash may cause it to be 'too lean' according to most but the extra cooling and octane will help make up for it. At cruise in closed loop the fuel trims will take care of it. I've found that adding 3 gallons of E85 to my tank changes the fuel trims by around 5-6%, so you will most likely run 5-6% leaner at WOT. If you are currently tuned to 11.0:1 at WOT on gasoline, your air/fuel will go to around 11.5-11.6 which is still in the acceptable range. If you have a more aggressive tune and it's at 12.0:1 currently, you will now be in the 12.6-12.8 range which would make me a little nervous. Now if you are talking about just adding a gallon or two, obviously the change will be a smaller %. [/QUOTE]
