Shiner, head over to Holleys website and download the instructions for the Sniper set up. I've got the set up but skipped right over the instructions for a MSD box, I'm just locking out my distributor and letting the system take control.
I'll take a look when I'm home and see what the deal is...just so I'm clear, you're looking to control timing from the Holley hand held using a MSD box correct?
