My 92 305 TBI camaro came with a stock ECM with the letters AXKW on it. The ECM went bad, and I found a relacement that I was told was out of a 92 305 TBI, but it has the letters AXKT. I have run it for about 20 miles, and everything sems koscher. What is the difference between these to ECM's?

 

if the part numbers are the same, it may just be something like when/where it was made, which line/room it was made in, ect.

 

Well, it stinks, because the original computer's part number is illegible, because the paper is all worn. The new cpmputer looks brand spanking new, and the car has been running clean. I am guessing if it weren't meant for this car it would have freaked something out pretty quickly. Am I correct on that assumption?

 

if it wasent right, it probly wouldnt run, or at least have the check engine light on steady
