Thanks Bob, for your detailed description on how the Regal/Alero GL2 tachs work, (or don’t) As you say, it could very well be something missing in the IP power-up. I will be looking for someone with a 97-03 Regal for testing and let you know what I find, either here, or by PM. This may take awhile, since I don’t know anyone handy who owns one!
