93 Cobra comp. in a 90 AOD ???

I understand the Cobra comp. doesnt have the best programming to it. In fact i know my A9P is better, but when i switched em a ran 4 diff. cars that i have lost to b-4 and a spanked em all. I had ZERO det. and the idle surging went away.(ie woke up) I have a 190lph in there. I had it dyno'd w/a wide band and my a/f was 13.1 across the board(no chip). dont think the comp will fry my engine, what FORD in Mich. said was my car will fry the Cobra comp.

heres the deal, my car is running hot 230-250(autometer gauge) so i took it to a shop at LVMS for some elec. work. They said they had to run another ground to the comp. and it fixed it. Running 210 on a 107 day(Vegas) When i went to put the comp. back in the kick-panel ALL probs. came back 230-250 again. W/the car running if you even touch the comp. the car will die(not to mention throw codes.) Today i was at the Track working on the harness and it seams to be one pin thats causing this. So im gonna do another harness 1st. Im tired of this the engine only has 2500miles on it and ive replaced ALL sensors twice and hg's twice and it all comes back to the comp. issues.

the car can idle for days and wont get hotter than 195. As soon as i start to drive 230-250. I fig. getting a bad reading from a sensor is causeing the comp. to compensate messing with the fuel/timing curves. I have a fluidyne rad. and an permacool 2950cfm fan. yeh its hard to type up a diagnosis but your replies are good enough for me. thanks
