Magnum EFi idea? Suggestions please
I have megasquirt on my 340, and I run a stock magnum distributor for a cam sensor (I use coil near plug so its not really a distributor anymore)...and my crank sensor is a $9 piece for a 3.0L ranger. The target attached to my crank pulley. Do something like this and you'll have it running in no time flat. The thing is tuneable to no end and runs extremely well. With a wideband it will get close on its own. I'm sure if you started with the stock magnum EFI parts, it would be a lot easier than what I did - just change to either a basic distributor or a crank trigger like I did and you're golden.
My car started the first time I tried it. Could drive it after one warm up cycle.
