Yep, thats why I said usually. Some PCMs can do that, some cant. and also not many are going to take the time to figure it out either. I was referring to gen III stuff that cant do it, 4 and 5 yes obviously.

Its airmass distribution more than anything. We did the coolant crossover thing many many years ago before anyone talked about it, but in the end it seemed that me running staggered inj (ran richer ones in the rear) did more for that problem. Didnt have ind cyl timing control on those ecus yet. Things I thought about before and during when we were running Hot Rod pump gas drags (Won it in 06 I think?)
Cant we just get a group buy on EGT and o2 sensors and run one in every hole? LOL
