why do you only have a 93 octane stage 2 + tmic map?

hi i have been throwing around intercooler ideas and noticed you have a ots map for stage 2 + sf + tmic 93 octane. why not a 91 octane map? i am stuck in cali all we have is shitty 91 and 100 octane race fuel for 7.59 a gallon help.... thanks anyhow

Open the stage 2 + tmic 93 oct map in ATR and copy over the timing values from a similar 91 oct map. That should fare you pretty well. Do some logs and make sure your good to go, might have to tune boost down a tad but I'll bet your fine. Probably best to dial in your MAF and create your own map sometime soon since your already working in ATR, but the above isn't a bad first step.

Cobb pretty much created the tunes with logs from our cars, so if no beta tester had stage 2 + tmic in a 91 oct state, a map wasn't made.

i took a crack at this, and it seems to have worked out well so far.

i took the ignition/timing tables from stage2+SF 91 and swapped them into my stage2+SF+TMIC 93 map. the "high throttle" tables were different between the two while the "low throttle" were not. i swapped the low throttle ones over but didn't notice a difference.

coming up on 100miles on the tweaked map, i'll mostly be looking to see if i get much KR at WOT. running 93 on the un-tweaked 93 map gave me minimal knock at WOT.

i had tried the 91octane stage2+SF map and found that it did not hit commanded AFR's at WOT, obviously because of the TMIC. i did run WOT this morning and saw that my AFR's were hitting target.

thanks, evidence! great first step.
