Converting to a MAF system

Hey guys - in reading through some of these posts, I ran across something about how converting from a speed density system to a MAF system would allow me to play with cam, chips & heads more, as well as help performance & mileage.

Can somone enlighten me on just what this swap would involve, and if it would be practical on this van? Is this a junk yard quest, or some kind of upgrade? I love to play with stuff - and dont think I can stop until I get this old van to smoke the tires for 3 city blocks at 6200ft above seal level!

Ok, maybe that is a bit much, but I do like to make 'em run good!

Thanks guys!

Did you ever get your OD tranny problems fixed? I have done about all the mod's possible to an '88 Ford F-150 Super-Cab, front to back. Can possibbly answer most of your questions about this vehicle.......

The easiest MAF swap would be a Ford Motorsport kit. However, you have to have a manual transmission or an automatic that is not electronically controlled. You could also get a mustang computer and custom wire the engine harness to match the new computer. That's quite a bit of work though. Another option is to find a 95 truck with MAF from the factory and take the parts you need from it. All three of these methods would include replacing the computer, wiring in the harness for the MAF, wiring the injectors to sequential firing, adapting the intake snorkel to go to a single tube for the MAF meter, and if you use the mustang computer, moving a few pins on the harness that plugs into the computer. The kit will include everything you need: MAF meter, overlay harness for injectors and MAF sensor, a computer, and a new airbox lid and hoses. However, you'll probably have to customize the intake because you have a van. All the electronics should be the same.

Yeech!

Sounds like a royal mess. Thanks for the advice guys! I dont mind playing with stuff, but I think I am going to stay with the existing system, and improve what I can. Thanks again!

Using the mustang computer (like I did) requires you to add a few things and change some other things to the current wiring harness. If you go that route use a computer from an 89-93 mustang - A9P is a popular one for automatics, although there are others. The A9L was for manual transmission cars, and also was made only between 89 and 93. Ford changed a lot of things in 94 for the 5.0 - the computer can be used, but it's different than the A9L and I'm not sure of the exact differences. If you are interested in doing the mustang computer swap, check out this page about a custom MAF swap: http://brembs.net/cars/maf_conversion/

I went with the Ford SVO kit. Had to do some alterations to the overlay harness to get to 351 firing order but that was easy. Well worth the money in performance and gas mileage and would recommend doing it to any vehicle. Added on a ShiftMaster module but returned it defective. Lost KAM on startup. If I had it to do again, I would have gone with the Tweecer, reset my idle to 800 rpm and do away with the EGR (sic GM) entirely.
