Sorry if this is a dumb question, ive been searching and I havent figured out the whole efi process yet

Welcome to the site!

The ECU and injectors depends on what system you are running. There have been a number of fuel injection systems adapted to the slant six. Everything from junkyard swaps using GM parts to high dollar aftermarket kits like Holley and Megasquirt. There is no "right" answer to your question. You will just have to do the homework and figure out what system you are going to build.

Welcome!

First: What are your goals for the engine, what car/drivetrain are you using, and what is your budget? Until you answer those questions, we can only guess how to advise you.

Thanks,

Lou

I plan to drive it on the weekends and have more of a street machine, I was hoping to turbo it in the future

grab everything off a 94-95 4.0 Explorer/Aerostar/Ranger. The motor is about the same CID and the motor uses a trigger wheel/EDIS (easy integration) and a TB wth an integrated IAC that is MEgasquirt friendly. You can run the Ford ECU and adapt almost everything to a slant. You can run the cam sensor off the old electronic distributor. EEC4 is almost self tuning even for a mild turbo application or go full custom MS1-3 and learn tuning from the ground up.

Thanks a lot! That was a huge help

Be really careful if you choose to graft on an OEM computer. If it controls other functions such as transmissions, body computers, etc you may be stuck having to emulate the sensors or reprogramming the computer if possible.

Take a look at EEC4 by Ford. The earlier models are more suited for adaptation without the said sensors inputs. The SC variant donor includes the 3BAR map sensor in the harness. There is alot of support for this ECU, maybe even more so than MS.

"...The EDIS-6 module is used on the following vehicles equipped with the 4.0L Ford Cologne V6 engine and 3.8L Ford Essex V6 engine between 1990 and 1997:

Ford Ranger / Mazda B-Series
Ford Explorer / Mazda Navajo
Ford Aerostar
Ford Mustang (3.8L V6)
Ford Thunderbird Supercoupe
Ford Taurus SHO V6 (1989–1995)
Ford Windstar..."

It kind of depends on how much learning you plan to do vs how much you want to spend. A junkyard ECU is often cheaper than an aftermarket standalone, but the tuning is often a lot more complex.

I think those were built in Seguin TX by Motorola. When Texas Instruments surprised Motorola with the winning bid, the Seguin plant was closed and sold to Continental. I think these controllers were a good design. My father worked at Seguin.

I talked to my father, he did not work much with the Ford EEC4 project at Motorola, but that was the bread and butter for the Seguin TX Motorola plant. Under its current ownership the Seguin plant is still a major automotive electronics site. Motorola was a Ford supplier going back to 1933.
