After a while of finally being where I can run E85 only in my wifes Tahoe I ran a log with it because I was getting a bit of KR* and noticed some unreal timing that I can't see where it's commanding it from. I am wondering if the AFR spark table continues on from where I can't see it. Tomorrow I'm going to 0 out the multiplier for spark/afr correction and try it out. Here is a log and a copy of the file.
The specs are
2003 LQ4
5.3L heads milled .015 with Ferrara 2.0" intake valves
LS6 springs
TR224 cam on a 112LSA
Stock cat back, cats, transmission, 3.42 gearing, stock airbox, etc. Truck is tuned for SDE since the maf calibration was just a pain in the ass to get right. Everytime I got the maf calibration correct since it was so far off it would end up needing adjustment again a few thousand miles later. Milage is just over 20mpg with the a/c on highway milage. Towing from Michigan to Las Vegas I seen between 12-15mpg with 3 tankfulls over 15mpg towing 4k lbs in 3rd gear. Anyway, here are the odd logs and copy of the tune.
