I'm currently researching, planning, and budgeting a speed density to mass airflow conversion for my 94 F150 5.8L with E40D. So far from what I have found is that a Mustang MAF ECC won't work with the E40D and my best bet would be swapping parts from a 95-96 truck with the same engine and tranny.

That or drop 1500 bucks on a conversion kit

Anyone have some advice, tips, or links that can help me on this conversion?
Any help would be great, thanks!

 

You have the right idea; find a donor truck with an E4OD and mass air and pull the harness, MAF, ECU and ductwork.

 

Luckily my K&N intake will save me from using the ductwork, do you know if the engine harness will be a direct plug in or will I have to cut and splice it in?

 

Retarded me I don't know if I can edit my post (lol) but I have found several possible donor vehicles in my local area. However, none of them are trucks with the 5.8L. One truck has the straight 6, another the 5.0L, and even a Thunderbird with 5.0L HO. The straight six is auto but the tranny was pulled out already. The Truck 5.0L was a E40D, and I'm not sure what the Thunderchicken had.

Anyone know if any of these vehicles could fit the bill?

 

A MAF 5.0 truck computer and harness for an E4OD will run a 5.8, it'll just need a trip around town to learn the motor's requirements every time the battery is disconnected.. which shouldn't be very often. Forget about a 6-cyl setup it can't run an 8-cyl, or the T-Bird, it didn't use the E4OD tranny and that's the 1 thing you absolutely got to have compatability with.

 

Cool thanks for the help. Hopefully I can start pulling the parts off before the weekend.

 

Can I use a 1997 f350 460 mass air setup to convert my 1992 E150 5.0 Speed Density to Mass Air?
Any info will really help
Thanks

 

That '97 will be OBD2 so the wiring is much more complicated, there are also 2 very rare OBD2 specific system you would have to source for your motor and given that you're likely not swappig a 460 into your truck tuning would be required to use smaller injectors. So that begs the question, why are you wanting a MAF conversion? If you are doing upgrades that requires tuning then the best way forward is to just go straight to tuning and skip MAF altogether.

 

MAF 460 vehicles were California compliant and only for 96 & 97. Finding a 5.0 with MAF and the same transmission would be easier for most people in the country than finding a MAF 460 as more vehicles were produced for more years.
The 460 trucks were exempt from OBD-2 requirements except in Commiefornia where they have their own EPA and stricter guidelines.
