Thanks for the links.:thumbsup: We're using the 8 pin ICM on 87 - 95 TBI trucks but, as your link shows, the only difference is the G pin for ground.

Interesting. I remember reading a thread somewhere about different ICMs' latency (is that right?). What about the D1984A? Do you know how it's configured?

BTW - that link you posted didn't...

What brand ICM do you have? There's a lot of folks that found cheap modules don't last long. I was just looking at reviews such as these, too many ICM failures on new equipment....
