Hey guys,
So I'm wanting to do a MAF conversion on my 1992 F-150 5.8L, e40d transmission. I've tried going through some other articles relating to this kind of job, however I noticed that the E40D transmission is going to make things a little more difficult. If you could send me a link to a previous thread that will answer all my questions on what is needed and what needs to be done or a link to a how to site I would appreciate it. The fuel injectors are stock 19lb./hr. by the way. I've been searching online for a while now, and I have all the codes for the different computer types, such as A9L, and what the car, engine size, year, transmission, etc. information off of a website. I'd appreciate a directive on which one's will work for this job so I can start scrounging junk yards. I've seen that kits are expensive compared to pulling a few parts and having a little bit of knowledge, so if you could share i'd appreciate it. I am on a budget. I'm looking in the future to put on AFR heads and change the intake, either an aftermarket or one off of a 93-95 lightning (which would be better? aftermarket manifold being Edelbrock performer truck intake). I already have headers, true dual, K&N filter, and a mild cam (I don't know which one exactly but it seems to be SD friendly as the truck runs great). Apparently the speed density set up holds me back so that has to be the next step. Thanks!

 

You'll end up using an ecu from a 94-95 5.0 truck with maf and e4od trans.
You'll add the sefi harness for injectors, and maf, along with repin your current ecu harness to make it work.
Wire diagram of the differences are on oldfuelinjection.com Under truck section.
The 5liter ecu will run the 351 just fine, and for your later mods you can get quarterhorse or tweecer to adjust the fueling and other parameters to get the most out of your combination.

You won't use an a9l unless you want to use a trans controller.
If you have deep pockets, find the thread 460 vs 454 and watch the powerblock tv show with the dunnrite mass air conversion.

 

Thanks, with the sefi harness you mean making your own? I saw in another thread people discussing this and copied the diagram that someone had posted on making one, bjoern i believe. And I wasn't sure how that trans controller worked. How do you have one ecu for the engine and another for the trans?

 

I use an injector harness of any sefi car. They usually unplug separately and are easy to graft into the truck. You could make your own by cutting up your current harness for the plugs and stuff, I'm just lazy and get one premade from the junkyard for $5.

The trans controller just taps into the sensors of the current efi setup. Then you can program it from there. It just uses the signals from the engine computer for tps and rpm and whatnot.

Keep searching and reading. You'll find tons of info on what you are looking for.
