Yeah I'll have to go back through my manuals and find out just what the ECM will want to look for as far as information it can read and respond to.

It's a third generation ECM and from hooking up the laptop to it I can pull a lot more information from it than I can from my 1987 truck, I was also playing around with the CCC1 ECM in my 1981, just to see what all it can or cannot read and do, it isn't much at all, but disconnect a single thing of the 5 it CAN read, and it makes the car run like it's missing a few cylinders and misfiring on the rest at best.

I know I will end up swapping in a 4 wire O2 sensor later on to make the computer react positively faster than waiting for the 2 wire sensor to heat up first, then only providing half the available information than the 4 wire can.
