Re: Megasquirt on AMC

[farna@xxxxxxx]

I haven't used it on an AMC yet either, but the principles are the same no matter what engine it's used on. I've looked at the MegaSquirt system hard -- if I didn't have my 4.6L stroker six running right I'd probably switch over! The MS is a batch fire system -- it shoots a small squirt each time a cylinder fires at all cylinders attached to one of two drivers. So it shoots to four cylinders at once even though the intake valve is shut on all but one. This works well because the back of the valve is hot and the fuel mist starts vaporizing as soon as it hits that hot valve. The engine turns fast enough that its only there so a second or less anyway. You just have to look at firing order and determine which of the four injectors is connected to each driver... I think. You'll need to look and see if both drivers fire at the same time or alternately. If at the same time just hook forur to one, four to the other. If alternately you need to connect in firing order --#1 to the firs!
 t driver to fire, #2 to second, #3 to first, etc. You'll have to read up on the MS to see how the drivers work, I forget! The only thing you need that is hard to get for an AMC V-8 is an intake manifold that has injector bungs in it. Edelbrock only sells theirs with their EFI kit, won't sell it separately. You can get alimunum weld in bungs. Don't know what a machine shop would charge to put them in. I wonder is steel bungs are available for a cast iron manifold? I don't think so...
