I've spent all weekend reading up on this MS. It is truly cake |(and wonderful cake at that!) And for a lot of you who really only need the fuel portion at this point, it's even easier. Already familiar with the use of an air temp sensor and coolant temp sensors (in place), along with using a suitable tps and then later incorporating a MAP that sees boost, I'm disappointed I didn't go this way initially. Really, a lot of the stuff reminds me of the 034EFI with it's simialr use of a map, albeit with a smaller 8 x 8 matrix.

I'll be SO using this with my 240sx setup. With a distrubutor already in place for my 240sx, I'll be able to have full control of my ignition as well, with an iginition map based off of boost and rpm. I'm so stoked.

If I were going 420a still, I'd merely get one of those unorthodox crank pulleys, and have a timing wheel bolted on to the side (or get one machined on) with a suitable crank sensor and go to town. Megsquirt N' EDIS is virtually the same as the Megasquirt N' Spark I'll be using. Each merely uses the Fast Idle output of the MS fuel controller which is unuseable in most setups anyways, and uses that to fire your coil. It's really that simple.

The only reason you can't use your current crank position sensor (and I know MrSlick is working towards this) is because Chrysler decided to use such a f'ed up crank timing pattern.
