    Anyone mind looking at my log?

    Guys i have a turbo truck and im seriously new to tuning, have read quite a bit and im afraid to make any changes to the tune myself any help would be greatly appreciated...i just put e-85 in it and commanded stoich afr to 10.39594 and it seems to be running a little bit rich under boost w/ Kr, idle is great and normal cruising is too....If you can depict anything off this file please let me know....

    Seems like you're rich across the board. I may be completely wrong, but from what I've found stoich for e85 is around 9.7:1. If you were to save that in your tune, it may bring your afr's where they need to be. Check your plugs and see if they look overly rich, then load the new tune and do another log.

    Thanks parks, and yes the tune was real rich even for e-85 i ended up taking it to the track to dial it in some more and pulling fuel wherever needed, also adding some timing.....ran 4 times and i dropped over 1.5 seconds over the whole night ending up with a 11.8 so far
