How to add computer controlled timing

From what ive seen, For the TFI distributor, you have to wire the hall effect up to switched 12v power, ground(or Sniper green wire) and the Sniper trigger input(purple wire). Modify the reluctor wheel to have even vanes. Set everything else up as Holley suggests for their Dual Sync distributor.

As long as you don't have issues with the VR, it sounds like the HEI is the easiest way for you.
 
Alright, well, I was successful!

I locked out the HEI, and switch the system over to magnetic pickup and away it went.

The adjustment knob mentioned in the video was phenomenal for phasing it.

I would suggest anyone who goes this route to get one as it made phasing the rotor a total cakewalk. I got it close enough to start up, and then told the system to hold a static timing of 10°. My lining up the internals got it close enough to sit at 12°, so I just turned the knob while pointing the timing light until it sat right at 10.

Inductive delay had to be raised to about 250us for the timing mark not to move when I revved the engine.
Working perfectly now. :D


So, I must say, after going through the process once, all of the above info about the TFI module makes a whole lot more sense.
I understood what the info was for, but I didn't get how it all went together until I saw it first hand.
I'll stick with this setup for now, since it's working well, but I might take a stab at the TFI sometime later down the road.

Thanks all.

Sorry to do that to you. Everyone cannot manage what they cannot understand.
