Can it be done? Could I convert my truck ( 94 F-150 ) to an OBDII set up, like the 96's??

 

I suppose anything's possible, but it would be a lot more work than it's worth. You'd have to add a whole crapload of sensors, most of which you would have to custom fit, and then somehow get a profile for your motor/tranny set into the OBDII computer.

It would probably be cheaper to go buy a '96 truck than to try and retro-fit a computer. OBDII computers are complex and finicky about tunes.

Unless you're looking for a monstrous challenge and a way to spend big $$$ on an old trucks for little/no benefit, I wouldn't bother.

There are tuner chips for EECIV computers, but they just monkey with the timing a bit to require premium gas. You can adjust the timing yourself in a few minutes, and get a decent boost in performance with a new coil, cap, wires and fresh plugs, and a slight advance in timing. Costs less than a tuner, and you can adjust it yourself.

 

Thanks for the info. I thought it might be a project that I could undertake, but obviously not.

 

It could be done, but I really don't see the point in doing it.

You can mod your truck a great deal even with speed density systems, and if you have really wild build stuff in mind you can go to an OBDI mass air setup.

 

I have mass air. I thought that by converting to OBDII that it would be easier and better to tune.

 

If you already have MAF, you have the best system available. You are golden. OBD-II makes it harder to tune, much harder since it actively looks for "tampering" (what the smog-***** call tuning.)
