is there a company that sells a everthing you need to install a maf on a 2.3, if not what is needed
It's pretty much a DIY thing, AFAIK there are no "kits" available. There are a few guys on Turboford that have done it, and a couple here as well (myself included). Unfortunately I have yet to completely document my install because I started on my FMIC / hybrid turbo install before I finished all the tuning - I didn't want to have to do it all twice!
You'll need a maf (I used an 80mm unit) and a way to tune the ECM to use it. Something like an EEC-Tuner (what I have) or a J3 chip adaptor work. Otherwise, a stand-alone unit (like SDS) will be necessary. Then a little wiring, some programming, and some tuning and you've got it.

The SDS and other stand alones don't use an air meter.
Ahhh. I didn't know that. :o
Sorry 'bout that, chief!
I see that lots of 4.6 Tbirds, Cougars, and crown vics have a pretty good size MAF. They look to be 70MM-75MM. Can I use this unit and what size are they? The Crown vic had a big plastic one similar to the one on my 99 stang and the 91 Cougar had a metal unit.
AFAIK, you can pretty much use any MAF you want as long as the output is 0 - 5 volts; the real trick is finding the MAF transfer curve (airflow versus sensor voltage) that goes with it. That's needed to build the proper table for the ECM to use.

Really! Do they just run off a wideband O2?
I'm just starting to look at those or the EEC Tuner for next year or beyond.
They run of the values you program it to run off. You tune the car using a wideband o2. The values you enter are what the car uses to run. It uses a MAP sensor to determine vac/boost and then uses the fuel and timing curve you programmed for those timing and fuel events.
SDS is speed density so it uses a MAP sensor. No support for a 4 or 5 bar map sensor, so you are limited to 29psi.
The t-bird sensor is a 70mm and is a good starting point for the MAF conversion. You will max your 35# injectors before you max the MAF. The 3 bolt mounting also makes it easy to mount and isolate from vibration.
Here is a list of MAF meters and size:

Transfer funtions are only good if you install the meter in the exact configuration as what they came out of. The transfer function is a good place to start, but to get it right, you need to datalog MAF voltage vs open loop AFR and adjust the MAF flow accordingly. Tuning the MAF can be done with a LM1 and rpm cable. Carzycarscott sells the package deal.
Here are the transfers I have collected:

Thanks I am a little confused. The SDS uses MAP and wideband O2 that I then calibrate the fuel maps in the program, so no MAF or VAM is needed, just an air cleaner on the turbo?
The rest of that statement about MAF sensor is if I am going to keep my computer and use the EEC tuner to calibrate the MAF to something the EEC exepects to see?
I'm kind of leaning towards a stand alone, as I like the end result of being able to manage everything.
