Through a bunch of research on this site and others, I was able to figure out the issues I was having on getting results to show up when bench testing some ECMs I pulled from the scrap yard. I did two 16197427s and one 1227747. Thought I would share my wiring schemes in case anyone needs these later on.
One thing I can say after testing the 160 and 8192 baud units is what a difference the faster speed makes! I thought I was having communication issues with the '7747 but turned out I was just turning the knobs to quickly on the sensors.
My test bench needs a lot of cleaning up but worked great for some weekend fiddling. Now that I've proven out the PCMs, I've started the TBI rebuild. I wired a vehicle for a Megasquirt application, so wiring the Corvette shouldn't be too bad.
Hope this info helps!
