I know this question has been asked but I can't seem to find it with a search. Which computers are compatable with a 94 Ranger 4.0, no EGR, Auto? Mine may have died and it would be nice to have a backup to plug in.

you want a 1993 Explorer or 1993 and the first half of 1994 computer, I don't know the specific numbers.
Frankly I'd go looking for a 1993 Explorer computer because they are more common.
They also have a somewhat more agressive tune, because explorers (for fairly obvious reasons) don't have the traction problems that Rangers do.
I'm certain I have one floating around here somewhere.

I have a Sploder comp. sitting on the shelf. I just didn't know it would work. You are right about the tune. The Explorer had a lot more power and it is the same engine (literally) in the Ranger minus the upper intake manafold. Thanks!

It's GOTTA BE a 1993 computer.
the 1990-92 are NOT compatible with the 1993's.

Allan's rite... earlier models were batch fire and the later were sequential. If you try to run a batch fire on a newer system, your gonna have a real rich running engine..... if it will even run at all. 
Done that.... been there... got the t-shirt. If you REALLY need a 94 auto computer, let me know. I have a "known to be good" one here.

I've got the 93 comp that came out of the same Sploder the engine came out of. I just didn't know if it would work as the Ranger had no EGR and the Sploder was an EGR system.

90-92 is the "grey" injectors and a Single HEGO
93 is "Red" injectors and Dual HEGO
SOME 94's are Red Injectors, Dual HEGO, EGR & SEFI.
the rest of the 1994's are the same as the '93's.
If you have EGR, you also have SEFI.

So, what does that mean exactly. I know what SEFI means but will this computer work with my application without making my check engine light come on?
Honestly, I think I just have a gounding issue. There are a few other wierd things going on as well. I'm checking all the wiring before I do anything else but if I have a spare comp it would be nice to be able to troubleshoot.
