Okay on the topic of SD tuning. How are we supposed to tune the VE above 4000 RPM on these ecms? I saw in the GEN 4 forums that theirs is all sorts of jacked up with zones etc but that was the E36 and E67 ecm, and the E40 i guess (from an 05 corvette) doesn't have the same features as the e36/67 and sd tuning on those is about impossible w/o a calculus degree. i thought our ecms were a 40 or a 36? any help on this would be appreciated.
