81 owners step inside

I am curious if any of you have tried/used the ECM performance chip from Jet Performance.

hey big bird, i know i am sorta hijacking, i have a vintage hypertech in my 82..... bought the car like that, ya know i called them and in order to remain 50 states

they only play with fuel and spark curve at wot, even for my "primitive fuel injection"

81 was the first year that all Corvettes came with a computer. It really was the dark ages in terms of automotive computer controls. The 81 CCC system doesn't control a lot of functions.

I've never touched the chip in my 81, so I don't have any experience with them, but I can't imagine that it would effect enough of the functions of the system, to offer a noticeable improvement in performance?

Biggest improvement to performance I ever did was completely eliminate the ECU system in my '81. Put a holley DP on it and be done with it. Or give one of the new TBI systems a shot if you want the drivability of a newer car. Granted, if you're in Cali or something that might be more difficult...
