Hey guys Ive looked around a bit but im not sure, I have a convertible 89 5.0 5 speed trans. I had a A9M in it that went out I have a C3W that i bought and was told it was good but it still doesnt run so the question is, Are the 2 ECUs interchangeable (A9M and C3W) or did I just buy a broken one.

C3W is an automatic computer. It is in the same line as an A9P. It still should work though, or at least start.

What is your current problem?
No crank or slow crank?
Cranks OK but no start?
Idle or stall problems?
Runs poorly or misses at certain speeds or operating temperatures?
Why do you keep switching computers?
