MAF Conversion clarification
Same old topic keeps coming up over and over again.
I did a search and couldn't find what I was looking for, and I went to fordfuelinjection.com and couldn't find what I was looking for.
What I'm looking for is what to do about coverting to MAF with a 302 and a e40d. I found information about using mustang parts for the 302, to switch it, except it doesn't work with the e40d. I found info on how to switch from a lightning with the 351 and e40d.
Does anyone know how to switch from sd to MAF with a 302 and e40d?

Kem,
Did the F-150 get 4WABS before the Bronco did? I mean that would be a little odd considering the nearly identical equipment for so many years. And even so, if the Bronco lagged by a few years the wiring for the 4WABS should end up superfluous if the truck the harness goes into doesn't have it. Not doubting you, just curious as to how that could affect things. Did the 4WABS computer get info from equipment other than the ABS sensors?

a guy on fsb.com tried using the same year f150 maf harness as his current bronco and ran into issues. he found that he had to use a bronco maf setup complete for it to work.

Oh and the fact that the F-series got the nifty factory break in the taillight harness to install a trailer connector where the Bronco didn't.

Yeah I have been doing a lot of research on converting my 92 bronco 351 e40d to mass air and it looks like for my truck which does not have 4wABS a 302 mass air computer w/e40d is the ticket. Only problems I can see is that it looks like the pin locations on the computer for the mass air 302 system go to different wires for the e40d vs. my speed density computer according to my chiltons manual. so basically I would convert your truck from 4wABS to the old style 2wABS and it might expand your options. Then again that might be more work than being able to find a 5.0 mass air bronco.

canadianice, in your case you still will need the entire engine harness and e4od/mass air computer. dont try to use your current sd harness. also are you sure you dont have 4wabs? if thats the case then you could use an f150 harness and computer from 93-95

I grabbed everything (harness computer dist tfi) from a 94 CA MAF 5.0/e40d bronco to convert my 92 5.0/e40d Bronco and couldn't get it to shift correctly because of differences in wire routing to the trans between those years. Part of it may have been because I didn't have the 4wabs module hooked up to the 94 harness when I put it in my 92. The MAF conversion part went OK, though.
My plan now is to convert to a 351 and go MAF using a 95 CA bronco 351/e40d EEC with a modified 1995 f250 (2wd) harness. There are some special considerations when going this route: the EGR setup is different (95-DPFE, 92-Sonic EGR), I have to bypass the 4WABS module to get the speed signal to the PSOM, and I must add another 02 sensor. The engine wiring end of things should be fine.
If you have the $$$ you can use the mustang EEC and a standalone e40d trans controller like the Baumannator. If you go this way, there is a lot more tuning support for Mustang EECs compared to truck EECs.
