We've developed a line of crank trigger wheels to make ignition control with Megasquirt or other aftermarket ECUs easier. Installing these requires some minor fabrication, and they'll work with VR type crankshaft position sensors (we don't currently stock the sensor itself, but plan to add that soon).

You can browse our selection at this catalog page (http://www.diyautotune.com/catalog/index.php?cPath=48) and check our our our documentation on how to use them with Megasquirt (http://www.diyautotune.com/tech_articles/trigger_wheels_index.htm). You'll notice that the car we picked for our initial installation happened to be a Mopar. :)

This isn't available for the 4.7 yet is it?

They're universal kits. They require a bit of fabrication, but we've tried to cover just about every engine with them. You'll just need to measure the outer diameter of your crankshaft pulley.

And with this I can control timing right? Could you guys read this info off of the crank position sensor or is this a mechanical unit?

This would let a correctly set up Megasquirt or several other aftermarket ECUs control timing. You will need to fabricate a bracket and mount a suitable crankshaft position sensor (most '90 and later Fords with distributorless ignition have one that works).

So I would just attach this to my crankshaft pulley?

More or less. You'd also need to fab up a bracket for a suitable crankshaft position sensor, wire it to your ECU of choice, and set up the ECU with your engine's timing requirements. It's a small cog in a big machine here.

Well thats not as complex as I thought it would be. How well do these work on coil on plug applications?

We haven't really tested it in coil on plug applications as we currently don't have an ECU that supports 8 cylinder sequential COP (well, we have a prototype, but no software for it yet). But if you combine it with a 1 tooth cam sync, most ECUs that support coil on plug ought to be able to use it.
