What is required/needed "ignition controller" to get a Ford 4.0L V6 motor that I am converting over to carb to run using the EDIS-6?? Right now I have a tired 2.8L v6 in my Tr7 that I converted years ago that needs replacing! I found a 1990 Ranger that had extremely bad body "rot" not rust but the engine and transmission are in excellent shape! Now to be really different I want to convert the 4.0L v6 to carb! I have in my spare time been fabing up a upper carb intake to fit a Holley 390cfm 4bbl. I run a fab shop specializing in aluminum work so I have the ability to weld using TIG and CMT MIG welding."

Hello and welcome,

We have a general, but comprehensive installation guide here:

http://www.autosportlabs.net/MJLJ_V4_ve ... tion_guide

It's not engine-specific, but it outlines all of the components you need for the installation and how to install them. You will likely first be interested in the information around installing the crank trigger wheel and sensor, since that touches your engine. After that is complete, everything else is just wiring up the components.

A 4.0L V6 sounds like it would be great in a TR6. Keep us posted on your project, we'd love to see an entry in our "Powered By" section of our forums.

In the meantime, let us know if you have any specific installation questions.

Best Regards,

So if your going the carburated route its best to use the MAP setup?? Would you be able to get away with a single vacuum port on the intake or would you be better off using 6 ports one for each intake runner?? Also how do you use the MAP setup?? Do you use any of the 4.0L v6's MAP sensor and wiring?? Where do you run the MAP vacuum line(s) to??

Hello,

Since you're fitting a single holley carb to a manifold, it's likely you would fit the MAP sensor vacuum line to a takeoff port near the base of the manifold where the runners converge. If there is a brake booster port on the manifold, connecting map sensor vacuum line to this point would be ideal.

The MJLJ comes in a version with a MAP sensor built-in, so you would run the vacuum line straight to the MJLJ box. You do not need to use any of the old electronics from the V6.

The factory-default ignition map is a reasonable "safe" map that can get you started.

I see you're making a custom manifold. In this case, I would review similar OEM style manifolds to see where they place the brake booster take off and copy that design.

Typically, it's located in the area of the manifold where all of the runners converge into the common area where the carb will mount.

If you have a picture or drawing of your manifold, please attach an image to this forum thread so we can all eyeball it together.
