So you are sending the unfiltered tach output into the PCM? I'm surprised that works at all, or for very long.
That’s was the first place I looked. I should probably mention (I thought I had, whoops) that I have aftermarket aluminum heads and that’s probably why it doesn’t fit.Road trip to the Bone Yard?
Thanks man, I really appreciate the encouragement. I couldn’t have done this without the help from all you guys.Always nice to hear them start up the first time. Your getting there
Took me awhile to sort everything out, but you'll get it
