I made a dyno video testing 91 vs E85 on lunds flex fuel tune. Need moar testing!

I think it is set to display the max of 77.6 . Our pumps are at 90% and mine is always 77.6 . My timing hits 30 on 91 and e85 however it's at 29 by 4500 on e85

I show a 5 degree timing advance on good e85. The test was flawed and im positive I'll pick up more power with pure e85. I'm guessing that was more like e50-60.

Oh, that makes sense. Yeah a few more degrees will be picked up on e85.

I'm gunna need to watch my timing again. I only ever saw 25 degrees on my x4 with 91. But yes. I experienced the same timing with e85. 29 timing very early, climbs up to 30... Gasoline on the other hand the timing seems to climb with rpm.
