electronic control module
 

i have an 89 cadillac sedan deville and the electronic control module (main computer)has fried out on me , i also own an 88 sedan deville with a fresh electronic control module and was wondering if you could use it in the 89 . the car is exactly the same besides the body type(same dash, all digital, and same engine )

Hey Dez: The ECM should work on the other car, It won,t cost you anything to find out, just a little time. I went to my jobber and got a recon. unit for like $160.00, you just have to take your other unit in as a core exchange. I had to keepmy calpac and prom chips from the old unit because the new unit didn,t come with them. The chip change is easy to do you just have to be very careful not to bend any of the tiny pins when reinstalling the chips into the new ECM. Good luck with that. Caddies are fun aren't they????
