Without the crank trigger you can't get a clean signal to the computer. I have spent lots of time and money trying to shield wires, have clean grounds, Magnecor plug wires, etc. but that stuff doesn't work. My tach signal is awful on the data logger and RPM jumps all around especially near finish line. Can't take advantage of my NHRA Accepted EFI system that does almost everything based on RPM. How will I ever get my E-shift to be accurate with this messy tach signal? I know I should have built a different combo silly me.

Oh, wait. Here's three different 305, 4bbl. Malibu wagons that won Divisionals this year, with irregular timing..How do you suppose that happened?

There's a late model GM in Division 1 that won 5 of them with regular timing, and great driving.
PS some rule changes I forgot: Fix the following stupid indexes
K/SA to 12.60, L/SA to 12.75, M/SA to 12.90 and so on..
oh yea, NHRA.TV on Thursdays should be a rule too!
