23mar10 rom has scaling of 713.
tried the following scalings: 680, 696, 731, 750.

whp/wtq results

713: 455@6500 / 417@5281
680: 448@6146 / 416@4885
696: 467@6083 / 419@4990
731: 456@6260 / 424@4958
750: 466@6177 / 409@5750

it looks like the 696 scaling is where it's at. i'm curious as to what happened with the 750 scaling, lower torque sustained higher than the rest. sounds perfect to me, but i am really curious if there was a turn while on the "dyno"  or something else that affected the log. for that log, afrs got into the 12.7 to 12.9, and the pro tuners suggest that this is too lean. other think that this is appropriate for e85.

for now, i will take a degree out at 38XX rpm, there was knock there, and i'll call the 696 scaling the finalized rom for 48*F. still, i'm going to investigate the 750 vs the 680 scalings. i wonder if the significantly leaner afr is some kind of break point for when there is a significant difference in the rate of combustion. will compare the afrs at the logged peak rpms (for hp and Q) and see if those aren't the optimized afrs for those rpm.

knock on wood, it's good to have the evo back up and running. it's just too much fun.
