ECU Operation
Where can I find a listing of sensor outputs and corresponding ECU actions? Seems to me this is needed to properly diagnose symptoms.
For example, my TCC is engaging too soon once the car has been running for a while - what would cause that condition, etc.

There is nothing in the stock ECM that you can change for that...gov, TC or ECM. That is a TC lockup setting that you can change with the EBL. Purchase a 82 GM service manual.

Also, EBL?
The idea behind knowing the input and output conditions was to help with troubleshooting. The TCC was just an example. If the ECU, uses inputs from sensors A, B and C for the TCC output, then I would know to troubleshoot those sensors.

OK, so I don't understand what your issue you are having specifically with your 82, your questioning is rather vague. The EBL is a new ECM that is 100% plug-n-play and laptop tuneable to your 82 if you want..

Purchase the “Corvette Fuel Injection snd Electronic Engine Management” book by Charles Probst. It will provide all the information you want.

I could care less about the books, I'm just trying to understand what the OPs actual problem is he is having with his 82. You can not set anything with the stock ECM. However, you can play around with some lockup settings for your 700r with an EBL and a laptop.
