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. |

the standard MSD box has no logic, all it does is get a signal to fire and it gives juice to a coil, for crankfire (wasted spark I'm guessing you want), the MSD will not be able to switch back and forth, you'll also need a device to control spark advance....for a pure race only motor, you could just setup max advance and it'll work if you ran two MSD boxes
the cheapest method I've seen is using the ignition from a pontic sunbird, no tuning, you are stuck with the factory advance curve, but it works (Clay did it years ago), next would be EDIS or find another 4 cylinder car that you can salvage parts from. if you want to spend real money, Electromotive is the next step... |
