E85 and the predator.

[BAFordF250]

2007 F150 5.4L FFV
Predator U7151

I have filled up with E85 and what i am seeing is that is has a octane rating of 100 to 105. now is the 93 ocrane tune for my predator enough or do i need to change some of the peramiters??

you can install the 93 octane tune and it will work great. The FFV portion has add'l programming for it, although if you want to try a little more timing it could be beneficial.

You are ok with the 93 octane tune. The tunes are written based off of your calibration/original tune. Should you feel that you need a custom tune for your e85 you can go to www.rune85.com
