unfortunately there was some new regulations recently passed that allow the e85 to go down to something like e55. The place that I go to now has a label saying something like 55-75 percent ethanol :(
I do have the flex and the car runs great on e85! The nice part is it runs strong on the 91 as well. BTW I am not trying to discredit Dyno Comp in anyway just my experience. They are or at least were very knowledgeable in the Subi world. Thats why I recommend Lund as they know the Coyote...
I had them tune my EVO back in the day and while it looked good on the dyno there was a lot of knock when daily driven (ended up tuning the car myself). Just make sure you run some logs on the road to make sure that you are not seeing significant knock. Have you looked into AMP performance in...
How do you guys drive the car while it is learning? It seems that I need to either idle or drive and shift at 4500 rpm to get it to learn close to the actual alcohol content. If I drive and shift under 2500 rpm it learns closer to 20%.
Working with them now. Doesn't seem like they think the percentage being that far off is a problem. Mentioned that others folks have had this resolved but it seems I may have to push a little harder to get them to look at it. Getting my original 91 tune converted to the ngauge as a back up...
If you are running a flex fuel tune you may want to go with the ngauge as it has the learn status data available. To perform the crank relearn you can get a married x4 for $100 or less.
