I am in the process of converting my 1994 F350 to an EEC-iv MAF system. I pulled the harness and computer from my 1994 F150. The F150 (donor truck) has a 5.0 and the F350 has a 5.8. From what I have read this is not a problem. Is it true that the truck sequential firing order is only 5.8 or 5.0HO and not normal 5.0 firing order? (that does not sound correct to me). Here is the big problem the donor truck has an AODE and the F350 has an E4OD. I originally read that this is a problem and you have to have a computer that is made for a truck with the E4OD only. I decided to order a remanufactured computer from a auto parts store and they categorize them as E4OD/AODE, like its the same computer. Can I use an AODE, 5.0, MAF, OBD-1, EEC-iv computer to convert an E4OD, 5.8, OBD-1, SD truck to MAF????

 

I found some literature that makes it sound like the e4od and the aode are the same to the computer and the regular aod is the problem. Here is what the article states:
To convert SD trucks with E4OD/AODE transmissions to MAF, some people use the CA 5.8
MAF/E4OD (F5TF-12A650-BYA). Mike Wesley says he uses the F5TF-12A650-HB (95 CA 5.0
MAF/E4OD) on a 750+ HP daily driver 415 stroker Lightning with a Vortech S trim. It
runs open loop, has been reprogrammed, drives like stock, gets 17 MPG and will run
low 10’s at 130+ in the 1/4 mile and A/C and cruise work great. Both of these EEC’s
are set to use 4.10 gears. If a smaller ratio is used, say 3.55, you could use the
F5TF-12A650-GB. There are probably 15-20 EEC’s available to convert a SD (later
model) to MAF (some of these may compromise the ability to stay emissions legal).
If you have an early SD truck with AOD, re-wire to the Mustang EEC (Ford MotorSport
sells this kit). You’ll have to move/add quite a few wires, and you might not like
the results if you’re not able to re-calibrate the EEC (like the Pro-M ’low cost’
kit, Kenne Bell, LCA and Downs Ford come pre-re-calibrated). The engine shuts down
at 85 MPH, shifting is fairly sloppy and too early (at least on a Lightning). All
Ford EECs shift poorly -- except for the Lightning, which is only slightly firmer.

 

If this part is true:
To convert SD trucks with E4OD/AODE transmissions to MAF, some people use the CA 5.8
MAF/E4OD (F5TF-12A650-BYA). Mike Wesley says he uses the F5TF-12A650-HB (95 CA 5.0
MAF/E4OD)

Then I can just use my stock AODE computer on my E4OD, correct? The MAF donor computer that I have has this ID on it:
HUG0
F4TF-12A650-APA

Can this computer be used on a truck with an E4OD?

 

Ford Fuel Injection » EEC Program Codes Have a read here. Looks like the computer you have is AODE/4R70W only and not E4OD. But see what you think.

 

thanks for the link, but I have had that data in an excel spreadsheet for about 2 weeks. It identifies my computer correctly, but it does not tell you if you can use that computer on a truck with an e4od. I basically have found information contradicts itself. Some sites no problem using the aode computer on an e4od and other sites that say no way it wont work. What is the real answer.

 

I don't have a difinititive answer on this but I'm pretty sure it's been done by somebody from here...

 

The 4R70W 5.0/5.8 computer uses pin 5 for an information input of the output shaft speed sensor for transmission shifts and a sensor return pin #29.

The E4OD has one more solenoid inside, the CCS solenoid (pin #55) and dose not have an output shift sensor. Does not use the sensor return pin #29 either.

I would think the fuel look up tables would also be different for the two engine sizes.

 

I was not aware of those exact differences with the computers for the 2 different transmissions. When I go to autozone or rockauto for parts I cannot find a remanufactured computer for neither a 94 nor 95 f150 with a 4r70w/AODE (whatever we want to call it). They only list computers for the C6 or E4OD. Why do you think that is? I was going to order a remanufactured computer for a 94 or 95 F150 with an E4OD. F150s in 94/95 all had MAF so I would be safe that way. I am worried that the listing for the computers for the E4OD maybe confused with the AODE. I have read that the rearend gears (4.10s 3.55s etc) are also programmed into the computers. All the computers listed in the link above are not available at rockauto nor autozone. There must be more computer IDs available that were used on the 94 or 95 f150s with e40d transmissions.

 

Yes there were a lot of different computer on 1994 & 1995. If you had the Calibration Code off the door post of a truck like you are putting together then we could look up the number of the computer that fits the truck.
You might ask in a post if someone on here has a MAF truck of the same year, engine size, transmission type and rear ratio that you are going to use and what their Calibration Code off the door post of a truck is. I think it will be a California truck.
It is more than likely the computer you are after is the F5TF-12A650-BYA.

Also they never put a AODE transmission in a truck, they only put them in cars.
They put the 4R70W in truck but they had a different gear ratio then the AODE so they took a different computer look up tables than the computers for the AODE transmissions. Some called these transmissions the AODE(W).
Yes they put different tables in the computer for different rear ends also.

The 1994 and 1995 5.0 SFI had the same firing order as the 5.8 engine.
But the harness going from the computer to the transmission was different to match what I said in the above post.

 

I just ordered a remanufactured computer from autozone. The part number is 78-6167. The info on the part is like this:
Part Number: 78-6167
Weight: 2.03 lbs
Warranty: 1 YR
Application: With automatic transmission
With Federal emission

Notes: O.E.M. #F5TF-JB
Application: Ford
Meets or Exceeds OEM Specifications: Yes


The F5TF-12650-JB is listed as a maf computer to use on fordfuelinjection .com

So this should work, correct?

 

It is listed as follows on fordfuelinjection.com:
WAY1 5.0 Bronco, F-x50 E-x50 MAF / E4OD / F5TF-12A650-JB (see note 1)

 

The F5TF-12A650-JB is for a 1995 E4OD Bronco 5.0L engine with a CALIBRATION of: 5-54L-R10.

 

Here is the info I get with the Calibration number (What does this tell me):

I pulled the engine harness today. Should I put bigger injectors in while I have it apart?

 

Not unless you have some way to tune the computer.
