The number off the sensor is E92F-12B579-AA and under that AFH55-03 it appears to be stock, its new, but I think a ford replacement... it says ford on it. Same with the housing... its new, but I think its the stock ford replacement...

And my injectors say... E6TE-A38 and they appear to be brand new as well... don't know what they are though... I guess thats a motorcraft number?

I got a 70mm Prof Products throttle body and spacer... and it looks like a BBK or mac fenderwell cold air. Into a Prof Products typhoon upper and lower intake.

Let me know if anyone knows anything!

Thanks for all your help!

What color are the injectors? If they are orange topped they are 19's.

The MAF has an '89 part number so it could be for a Mustang

12b579 = mass airflow meter
afh-55-03= 55 mm

and yes orange inj = 19's
blue = 24's

This is on my 90GT... and the top of the injectors are orange. So these are 19lb stock replacements and the MAF is stock.

Now if I move to 24lbers I'd need to get a new MAF housing calibrated to 24? Would the superchips accept it?

For larger injectors, a chip or custom tuner is the best method.

MAFs calibrated for larger injectors were fine 10 years ago, but it really isn't the best method since all they do is "trick" the EEC into the amount of air the car is seeing. These days, the proper way to calibrate is chip or tuner

The guy I bought the car from already has a superchip. I dont know if its tuned or has a chip in it. I though superchips did away with the EPROM type deals. So being he did this recently, it must be an SCT tune. So that means its tuned for stock injectors and maf.

So I'd need to buy a set of 24lb injectors, and have someone tune it? Or do I need the 24lb calibrated MAF as well as the tune?

There are so many questions being posed I cannot begin to address them all.

If you want to know what combo you have now, pull the passenger kick panel cover and the computer. You will find an adapter plugged into the J3 port of the computer. If it says Superchips, then that is what you have.
A superchip should have a parrt number that can be traced by superchips.

If the tune is custom, there is no way of knowing what your tune is.

I am not sure on the part number of the MAS. I used to have a link to a decoder, but I will have to look for it.

Good MAF's don't "trick" the EEC...C&L does, but get a good Pro-M unit with new electronics and you will get a solid, accurate read to match your injectors.

Sure, it costs more, but as they say, you get what you pay for.

The Pro-M unit may be more accurate than the C&L but is does not change the MAF Transfer file in the EEC. It still is tricking the EEC into running the proper a/f ratio.

In my mind (I have been using a tweecer for a few months), the Pro-M meters are barely better than the C&L meters.

Pro-M has a more accurate way of tricking the EEC, that is all.

Unless you have an aftermarket tuner, you are tricking the EEC.

I have an aftermarket tuner - PMS. And Pro-M's are generally considered far more accurate, especially if you are blown or not using the factory airbox (due to the ability to measure 360*, unlike the C&L units).

I guess I mispoke...or something to that extent. I guess "tricking" the EEC is something they all do...but the C&L meters trick the stock sensor, by controlling air flow to it via the sampling tubes. The Pro-M units use specifically calibrated electronics, which cuts down on electrical interference and provides a smoother air/fuel.

I had a C&L previously, and I liked it, so don't get me wrong, they are decent units. But when I got a blower, I stepped up to a Pro-M instead of just getting a new sample tube for the C&L.
