Hi all,
I'm working on my '85 Bronco with a 300 I6. It has a Holley Sniper EFI system.
Currently it has an aftermarket DUI ignition from PerformanceDistributors.
However, I want to go with computer timing control using the Sniper system.
It seems the more research I do on this, all I get are "clues" but never anything directly definitive and it's getting very frustrating.
I asked on the Holley Facebook Sniper group as well as the forums on Holley.com and again, just more clues, or guiding suggestions. Never any real help.
ie. "You need to lock out the distributor and then set up the ECU to control the timing."
Yes, I understand that's what needs to be done, but how?
Also, which system would be the best to use?
I have 3 options that I know of.
DuraSpark II: First would be the DuraSpark II ignition system. I have the full working system in a box in the garage. I have also set it up and modified it already to work with the Sniper. However, not with timing control. It's still using mechanical and vacuum to advance. I'm open to the idea of integrating an MSD 6A module, or Holley's HyperSpark (which may or may not b easier to set up).
HEI DUI: I have the DUI setup already in running on the engine. Again, without timing control.
Ford TFI: Get a distributor from the 87 - 96 era. I like the idea of using a distributor that's already set up for ECU timing control. However, Holley said this would be difficult to set up (even though they didn't say why). But if it's a good option, I am all for it. The downside is I don't have it on hand so would need to acquire one.
What would be the best solution? Ideas? Thoughts?
