Ok so I like my carbs and I thought hmm wouldn't it be neat if I could hook up a crankfire system. I mean really I've got the msd installed, so whats next? I need a magnet set on the flywheel a magnetic pickup on the fan housing and a coil pack right? Wont the MSD handle the coil switching? I dont want to go full blown Megasquirt or anything like that just want crankfire with the carbs. I have a buddy who was going to design one for me but he still has a couple of tug boat diesels ahead of me and it looks like it may be awhile.
Thoughts? Can of Worms? Mike D. |

Some MSD boxes appear to have an input for a Hall-effect sensor, but I don't know much about what it does. I expect they only work with HEI distributors (trigger wheel advanced by the distributor) or the like. They do have some crankfire setups, but like Mike said, I think they're also basically fixed advance, which is fine for drag cars and the like. For actual ignition control with crankfire, you'd need to use either the Electromotive HPV setup (very expensive, like $800+), which uses a 60-2 toothed wheel you'd have to mount somehow (probably behind the fan). You can use a DIY system called MegaJoltLiteJr, which uses a small bit of electronics to hook up a Ford EDIS system. Much cheaper, at roughly $200, and fully programmable, but you still need to mount a toothed wheel (36-1, this time), and ther's a solder it together yourself aspect. Other than that, you're looking at just using the ignition side of an aftermarket fuel/ignition ECU. SDS and Perfect Power will both handle magnets on the rim of the fan, but you're looking at roughly $1K to get there, more or less. |
