Just to throw an idea out there...
Anybody considered making trigger wheels?
I've got a 5" in the works that was cut from a chunk of 5" bar stock (like slicing
sausage).
For the trigger device, a crank trigger from a 3.1 V6. It's a MR unit, so all it
needs out of a wheel is for it to be ferrous metal, and have regular spaced
notches. Can make the notches however you want, really.
This generates an AC signal, which can be used with pretty much any ignition
you'd want to use it with.
I'm attempting to set up a DIS system, which, if it works, will cost a DIY
'er <$100. Should also be a plug-in to the stock ECM.
More on this as the project develops....
