I've been putting together my new 2+ litre engine and have been looking into flywheel fired magnetic ignition. The crank fired ignition won't work too well I guess since the front of the engine is buried in air ducting.
I am contemplating installing two of these into my flywheel to run a MSD 6AL system. There is a nice inspection hole on one half of the case that would be perfect to mount a pickup in. Anyone tried this beofre and if so any pics or suggestions? Thanks! -JR- |

I wonder if a suitable setup would be to mount magnets on the fan, and point the sensors down through a plug machined to fit the timing hole in the shroud. Two sensors, one "south pole" sensitive, the other "north pole" sensitive. One could arrange a system where "north" was 1/4, and "south" was 2/3, with the magnets about 40-50d BTDC. This would give enough data for wasted spark and bank-fire injection. Wouldn't work with EDIS or SDS, and probably not with any other off-the-shelf system, but some custom code for the MS hardware would work with this. A modification with three magnets could accomodate SDS. The two magnet setup would be REALLY easy to generate the D-Jet trigger points signal from, so one could make distributorless ignition for D-Jet.
Hmm... Adjusting the sensors would require machining a new plug, but as long as the sensors and magnets aren't off by more than a few degrees, adjustment could be made in software. Big question is (don't have a car handy): can you get the sensors close enough to the back rim of the fan from the timing hole to sense the magnets accurately? You probably don't want to mount a magnet to a fan blade, and the thick "pillars" aren't conveniently located. I'm turning into Mueller. I'm considering going Soob, but still thinking about Type IV EFI systems... |
