ah that's better, but why is the Tach Output set to 6, is it for a 6 cylinder, I thought the PCM put out a signal for a 4 cylinder.

It does put out a signal for a 4 cylinder, 24/4=6 and that's all I know, ha ha and 24/8=3 and that's what we need to change both of those numbers to is "3"

by the way 24 is the number of teeth on the reluctor wheel in our Gen III LSers
