Question on dual plugging EDIS ignition
 

I need to consider dual plugging. Doesn't appear to take a lot with EDIS already in place. But uncertain as how to configure such as system. Run 2 EDIS modules off one VR sensor ?

I guess I would need different lower covers. How to protect plug wires from road grid, salt water and debris ?

Works fine with one VR sensor. I have 964 upper and lower covers on mine. I drilled the 6mm holes to 8mm or modify stock lower covers.

I ran parallel EDIS controllers in a twin plug setup for quite a while. It works very well. You split the VR signal to both EDIS controllers but only need to wire a single PIP signal from one controller to MS and then split the SAW output from the MS ECU to both EDIS controllers.

Excellent.

Then I need only to find someone to machine the heads. I'll see if I can get away with running the sparkplugs leads under the covers
