Ford EDIS 8 Retro Fit

Has anyone had any experience retro fitting a Ford EDIS 8 system on their engine...or for that matter an EDIS 6 or 4? Along with a MPFI, I'd like to control it with a Megasquirt/EDIS 8 fitted to my 291 Hemi. I could also use ANY info on how hefty a Roller Cam I should have cut, to take advantage of this. I figure that if I brought the little Hemi into the 21st Century, that it would be a NICE runner, and be able to hold it's own...

I used the EDIS-8 and Megasquirt on my 4.6 DOHC blower motor. The EDIS connections to the MS were simple and it works great. You'll have to workout your own ignition curve, but you might get some help from the MS forums.

My motor orginally had the EDIS setup, so the trigger wheel and sensor were already there, but you should have no problem mounting them to your motor.

Can't help you with your cam selection though, sorry.

What are you using for an induction system?

Right now, I have the stock '55 4V dual plane intake. 'Hamilton Intakes' is in the process of producing , among other DeSoto intakes, an aluminum single plane 4V intake and I think I will wait for that. Since I will need to have a new cam build, I was thinking "Roller", to take advantage of the rest of the upgrades (modern cam technology). I don't want to build a Drag engine, but I want the best Street engine I can build...without getting silly about it. I see no reason why the little (cubic inch!) Hemi shouldn't be able to keep up with today's current offerings...if it had the same technology retrofitted.

You know, somebody said that I could gut a carburetor, but that the flow area needed to be calculated at the venturis not the base plate. Any more info on going that route?...

Basically, the carburator is simply an air valve, as long as it's big enough for your engine, your good to go. The computer could care less what you use for a throttle body, no flow area calculation required.

The Megasquirt uses a vacuum signal from the intake manifold along with information from a handfull of sensors (intake air temperature, RPM, coolant temperature and throttle position) to calculate the correct amount of fuel to deliver.

Not sure how much research you've done on the MS, but it's not plug and play. Read this manual front to back twice and things will come much clearer, if you haven't already.

I had originally thought about the Holley 950 Commander MP, but it's the entire "Universal" package in one bite ($$$). The MS appears to be more programable, and I can custom taylor the FI system with what will work best for the Hemi. Yup, I know it's not "plug and play", but if I'm going to program it myself the MS looks like the better set up. As for using an AFB, its not a big deal to fit a TPS to it and gut it. Just need to come up with the largest CFM that will fit...within reason. Believe it or not, the BIGGEST hurdle appears to be how to plug the distributor hole and hold the cam driven oil pump gear down...

Other than for appearances, why would you want to use a carb as a throttle body? The venturi and booster venturi would be a flow restriction and are not needed. If anything, you might want to consider hogging out the venturies and pressing in tubes that match the throttle bores. Now it would look like a carb but not have the flow restriction. Of course, you still need to mount a TPS.

Joe,
Appearances...operative word being "gutted". For throttle bodies going for most of a $500 bill, I'd consider doing it. Once the Air Cleaner is on it would probably look fine. If not, I can go the throttle body route and haven't lost anything. HOWEVER...Retrotek sells a REALLY nice throttle body for under $400, which is a much better choice and what I'll most likely go with...
