Yes I looked and I was wondering is there an OBD1 MAF ECU for the 5.8? If so where can I find one or get one a part number would be helpful.

mustang computer?

Why not go with an A9P or A9L computer from a 5.0 mustang? I believe they can run a 5.8 and you can use a tweecer or moates quarterhorse if you find you need a more precise configuration... you will probably have to do some wiring anyway, right?

Wiring I have lined up just need the ecu is all. If one for a 5.0 will work then I can grab it from work and a 5.0 truck MAF ECU then get the harness and I should be set.

Someone please correct me if I am wrong, but I believe the mustang 5.0 computers have a more aggressive stock tune than a truck computer would have, which is why they are so often utilized, plus they have the J3 port which allows for the Tweecer or QH mods. Check it out, I found an A9P (5.0 auto trans (not computer controlled trans)) on CL for $45 shipped...

If the E40D is a computer controlled trans, then you can't use an A9P or L because they have no provisions for computer controlled trans (stick or c6 like trans only)

Be sure and warned. I hope you know someone or have someone in the are that knows how to use a tuner. Or, if you have any experience with a tuner. Especially with a Moates. It's not as easy as 1,2,3. lol, And , if it is for you. Be expecting a PM from me. lol

Good luck my man.

Yes the Mustang computers have a more agressive stock tune than the truck, they also have more "stream lines" for tuning with tweecer than a truck computer.

Also even the SD eec's have the J3 port.

Heres my plan:
I want to do a Mass air conversion on my 89. My plan is the get the SD to Mass air harness for RJM, a 5.0 Mustang eec from 88-93 (with auto, w/o computer trans, cause I have AOD), and later a tweecer for more tuning.

**Another thing, If you get a Mass air computer from 94-up you have to move the air temp sensor to the air box.**

I have the air box with the air temp sensor in it with the mass air, getting the harness isn't a problem either the ECU is what I need. If I can run a 5.0 ecu for an electronic tranny then I should be good if I am assuming correctly.

Well I have a 94 Bronco 5.0 Mass air with the E4OD.

So mabe you should get a eec for a 94 bronco 5.0 w/ E4OD. Cause the wiring harness you have is for a 94-up eec

Stay away from OBD-II 96 stuff. Go wth the 94 ecm that has been mentioned.

Disregard my reply about tuning. If you are keeping the motor stock, you should be fine I believe.
