The idle air control is an after market housing that I had left over from a previous project with a GM IAC motor. The MAP, ECT, IAT, and knock sensor, are all GM TPI parts. The TPS is a Ford truck unit because it was easier to mount. The distributor is a Frankenstein unit with the Chevy bottom and a Ford Duraspark top and a remote mount GM HEI module. A good friend of mine is handling the ECM mods. He has the ability to log and modify the fuel and spark tables and burn a custom chip for me. It may take some time to get it tuned properly, but it should be worth it.
I am installing a Gear Vendors overdrive unit also and he tells me we can control it with the torque converter lock up circuit since it is electrically shifted.
How do you like your system compared to the carb. Have you noticed any improvement in power, drivability, or fuel economy?
