Re: Efi sos!
I have responded to over 20 emails of late about electronic ignition for the Sniper, and I have said that the Sniper isn't the friendly system it claims to be, far too intensive to work with, and as far as ignition goes, there is not a viable solution. their dual synch is way, way too expensive, and the trigger only with adjustable rotor is down right primitive. I am also hearing the same for one of the FiTech EFI's, same situation, ignition input does not use a module, only a locked out pickup trigger only.
A couple of people have swapped to th Holley Terminator, and old small diameter stock GM EFI HEI distributor with feed back module, and are seriously happier, their opinions, not mine.
Don't flame me, this is what I put up with every day. I am now doing two International Harvester Sniper setups, and they do not have adjustable rotors, but, I am factoring the rotor phase into the timing as I phase them on the machine. So far, I understand from the callers and emails, that I am the only one that will even consider doing an ignition for a Sniper that ISN'T an MSD trigger for Chevrolet/GM units with adjustable rotor.
Terminator is far better from what I see. I used to work at Holley, Pro-Stock carbs.
