I'm back, been busy moving and a few other things, but now i have some time to get back to tuning. I manged to get the
mechanical temperature gauge
hooked up so i can verifiy that the computer is reading accurate. I need to get out and drive to confirm but so far it looks accurate. I manged to find another 8747 as a back up. I'm going to leave this one untouched and keep in the truck just incase. I also found a 91 suburban 350/4l80 computer. Paid way to much for them. $65 each.
