1994 MAF Upgrade
Last fall I got a 1994 Flareside SC 4x4 5.8 E4OD. Getting ready to do MAF upgrade this spring. I have ford factory service manuals and wiring manuals for both 94 and 95. I got lucky, (I think), and found a 5.8 MAF/E4OD computer F5TF-12A650-TB, SMD-272, FLY1. Also got a 1994 5.0/E4OD harness and air box, MAF, and air tubes from Don @ H and W Parts phone # is 1-877-665-5444. They also have an ebay store "handwparts". Anyhow, looking at the wiring diagrams shows there are quite a few differences in harnesses between 94 and 95 leading me to believe there's going to be many pin changes to the harness besides the injectors, MAF, and IAC. Am I correct, or reading things wrong. Have read many posts here on FTE and can't thank you guys enough for all the knowledge about this upgrade. I have read a few posts though where guys have had horrible problems with their conversions and it dawned on me that with the differences between 94 and 95 harnesses that maybe some of those could be due to this issue. Thanks in advance for any and all input or insight. Jim.

According to what I have found about the FLY1 is that it is AHACA and was used in the 1995 Bronco w/E4OD. Took a long time searching to find the info on it that I have. Yes it has a usable J3 port and when I get everything done will probably get a tuner for it. This is gonna be a couple year project in the little spare time I have but eventually I will catch up with you guys. LOL
Eventually planning on 35's 4.56's etc. etc. etc. This truck was up-fitted, and came with every toy the owner could order on it. Factory alarm in 94 and even Limited Slip Differentials front and rear.

Yea, I'm gonna have to do more checking on this EEC. What I read on oldfuelinjection.com last winter listed it as AHACH and a not very common computer, but still tunable. Now the site is not accessible. I'll have to give tweecer a call and find out for sure when I get to that stage. I really appreciate any and all info you guys can provide though. Gonna be even more fun on here taking all the electronic 4x4 out at the same time too.

I think I might have some problems using the FLY1. The diagrams I've looked at seem to indicate that there are significant differences between the 1994 and 1995 emissions installed which has completely different wiring and sensors. Does anyone know for sure? If that's so I would probably be better using the HOGO computer I have which is for a 1994 MAF 5.0 and tuning it. Any GURU insight or info would be greatly appreciated.

There are a lot of differences between the wiring on a '94 SD truck and a MAF truck but between OBD1 MAF trucks not so much and sensors are all the same excluding the MAF meter of course. Emissions equipment has little or no impact on the EFI system either way so that shouldn't have much influence on what PCM you choose, like RIKIL says use whatever one has the best support from the tuner community because ultimately once you have a tuner it won't metter if you start with a 5.0 or 5.8 PCM because that is easily changed.

nojoke. The reason for the MAF change over is I have owned a few of both, and hands down the MAF trucks ran better and smoother. I had a 95 5.8 ex-police Bronco that was an absolute monster. Unfortunately I sold that truck. On dry pavement it would pick the front tires about an inch, and on wet you had to be very judicious with the go pedal. I would really like similar performance. Plus it got the best mileage of any of the trucks/broncos I have owned. And lastly, I've never been one to leave well enough alone and I love learning semi-new things. LOL
Paul and RIKIL, thanks for the input. Just by looking it seems probably 10-12 pins will need to be moved besides adding the injectors and MAF, does that sound about right. Even some of the E4OD pin positions are different along with the VIP etc. Sound right?

These are the same as the pin-outs in my manuals. If you go down the lists you'll see many differences. Don't get me wrong, not overwhelmed about this, just wanted to make sure before I start that my assumption is correct. The new computer will be the FLY1 we spoke of yesterday mot likely. Thanks again guys.
