replacement computer for the a9l and a3m, was installed in some late 93's and is what you used to get from Ford dealers when you needed an a9l. Only main difference with the a3m1 is it has a 7000 rpm rev limit, and it has to be modifed to accept aftermarket computer chips.

Window switch. Do you have this computer? If you do, I will swap you my a9l as my cam is going to need a little more than 6250 :D

It is for Automatic rides also. I had one in my TownCar. I have a C3W1 in my F-150 now.

I remember that auto computers will work with A4/M5 and the stick computers only work with M5's.

Stang pie...if you have a regular A9L I will trade you :D

Someone said it was an auto computer....The auto computers are A9P's right? This A3M1 is a member of the A9L family so I thought it would be a manual tranny computer. Can anyone verify wether the A3M1 is m5 or a4?

I USED an A3M1 w/ an AOD and can verify that is for an Automatic without and AirBag.

From what I remember the Auto computers can be used with Sticks too.

Also I believe that A9L and A9P are the '89 years only. I may be wrong on that tho'. The other numbers and letters are the later ones.

the a3m and a3m1 is part of the a9l family, it is not part of the a9p family, thus making it a 5 speed computer. The 5 speed computers can be used on auto cars, however one of the o2 sensor wires needs to be moved on the harness, so you don't burn out the sensor.

That's weird. I had the A3M1 backed by an AOD. It ran fine. Nothing was burned out sensor wise.

Ford sent me the wrong computer (an one M5) and the car ran worse with the wrong computer than it did with SD!

So... M5 computers need to be changed up to run with an A4 while A4 computers can run on an M5 with no problems? :confused: <--- That is how I feel now.

On the last car that I put an a9l or equivalent manual trans computer in that came from the factory with an a9p computer (automatic) I had to swap one of the o2 sensor wires so it wouldn't burn out the sensor, it was an 89 car so, it might have just been wired wrong, however I have talked with a couple of other people that have had to make the same change, so YMMV. I have never done an automatic computer in a 5 speed car so, I'm not sure if you would hafta do the change on it or not.

Oh I gotcha. You put an A9L in former A9P Automatic car. I see why the wire swap had to be done now.

:) Now I caught up on things.

You know why? B/C Automatic computers are compatible with A4 and M5! Like I said earlier. Jeez does no one listen? ;)

The M5 computers have to have a slightly modified harness apparenlty to be able to run with an A4.
