Engine and Transmission Tech

Anybody out there have some electronics experience?

I suspect there’s a simple solution to connecting FiTech EFI to an EDIS ignition controller, but I don’t know what I don’t know.

FiTech EFI systems can control ignition if they are coupled with a compatible “2 wire” distributor, such as MSD and DuraSpark. Those distributors send a simple signal to the FiTech computer that indicates cam position, and receive a simple signal from the FiTech controller. I assume the distributors contain a hall-effect sensor similar to what EDIS uses, but I’m not sure.

I found this quote on a vintage mustang forum about using FiTech to control a Ford EDIS8 trigger wheel ignition setup:

“neither the FITech or the Sniper are configured to produce a PIP/SAW signal that the EDIS system can use. It does have a two wire output and it seems like a simple firmware upgrade could enable this, but for now I'll be keeping the megajolt to control timing.”

Here’s a great overview of the EDIS system, and the PIP/SAW signal details between the EDIS controller and an EFI computer:

It seems that two wires between the FiTech and the EDIS is all it would take, but I don’t know if the MSD/DuraSpark signal inputs are comparable to EDIS signals, or if the FiTech signal outputs are comparable to MegaSquirt signals, or if it might be easy to translate the signals using some simple hardware wired in between.

I know MegaJolt is one answer, but I’m wondering if something simpler would work?

Someone on here stated that FiTech does not and would not support EDIS.
I looked at it and found the same info you linked to. I fear it won’t do what you ask even if it looks like only two wires. Won’t even work with most other people’s programable distributors.

If you have the patience, call the Fitech hotline - they have some pretty knowledgeable folks there.
