90mm Lightning MAF on my 93 LX?

[Stangonline.com]

Ive been told that this works - just have to rewire the harness.
I have also heard that LMAFs arent calibrated for any particular injector, rather they get it from the EEC. Is that true, and if so, what does it mean to me? :)


Any info? Will be used with 42lb injectors.

Thanks

Don't. Not worth the hassle of getting a chip burned for the different transfer function, etc...
I tried it, had 0 luck and just bought a Pro-M. Car ran like a top even w/o the PMS, whereas with the LMAF it'd slobber so rich that the plugs were fouled in 10-15 minutes!
If you do do it, you'll need a chip burned for the different transfer function of the LMAF and also wire the different plug into your harness. You can pick it up at a dealer for like $15.

So it basically makes the computer tell the MAF what size injector to work with? Wierd.. Sounds like there is much more to it than putting the correct harness on..

O well. A chip at this point is out of the question - so perhaps Ill just shoot for another mass air meter... sad day for a broke dude like me..

Thanks

I wouldn't be sad man, I solved my LMAF's problems with a BFH and man did it feel GOOD! Putting that Pro-M on there was the best thing I've done other than the PMS for getting the car to run well. Now it'll lug along at 13-1400 rpm without bucking and such, whereas before it would hardly run!

Did you get the pro-m that was specifically for the powerpipe?

[Jon01]

Don't know that they make one for a powerpipe, I had to use a silicone hose coupler to attach it to the pipe if that's what you mean...It's not the chrome bullet, but the full body with filter attached on the end.

Working on selling the LMAF and getting the pro-m. Which of the 80mm did you get. I see the full bodied plastic ones. Do they specify when its going to be used for a draw-through, or does that only matter for blow-through?

You car sounds similar to mine, got any pics?

The Pro-M 80mm shorty is the one.

I got the n/a cal from AFM. I do believe there are forced induction cal's too, but it seems everyone agrees that they're easier to tune.
I don't have any recent pics since all the changes were made, but it does look exactly like yours other than being a hatch with Bullits and the black moldings since it's a 90. I'll put some up when I get time to snap em. Your car is SWEET! uNf! ;)

I have "heard" that alot of tuners prefer the regular calibration meters as opposed the the S/C calibrated ones as well.

[Jon01]

That's what I've heard too. Something about the n/a cal's being more predictable or something since the s/c cal richens up on the top end or something.
