Cool. Sounds like it's worth investigating. You will want the T4M0 or J4J1 (Cobra) catch code to start.HarryS said:Yes, Massachusetts does require the air pump, but I took a list at your pinout list and it looks like pin 31 controls the air pump and it appears to be supported by the 94/94 computer.
UPDATE... OMG my car is way faster and smoother. I put those 24lb'rs in and copied all the j4j1 tables and scalars to my t4mo bin. For some reason the j4j1 bin gave me a rom checksum error code, so I didn't use it. Going with a fox style intake was a godsend today in the hot shop. I had that sucker purring within 30 minutes.However, if you aren't up to tuning this yourself, you might be better off going this route and just having Lonnie Doll create a program for you and sending you the chip.
Honestly I couldn't tell you since I chose to go a different route and not have the ECM control my fan.icantdrive55 said:I have a question about the ccrm on a '94/95 Mustang. My diagram shows the 2 relays and a solid state control that runs them.
Does the computer shut off the low speed relay when high speed kicks in? Or is that a function of the solid state edf relay control?
I'm guessing you wouldn't want to run both speeds at the same time?
I'm assuming a 4.6 tbird would function the same way as the mustang, if anyone knows.
On a side note my '98 MarkVIII fan is drawing 50 amps. Draws 35 when out of the car. The thicker radiator seems too restrictive to airflow. Paid $107.00 delivered for a '94-'97 tbird fan. That sucker only draws 30 amps no matter what. The motor is much smaller with the same housing and blade. The actual blade adapter is different though. I might just use the 2 speed feature of the tbird fan.
I wouldn't trust them. They may swap physically but I doubt they are the same.dwinthrup said:The junk yard told me that the v6 mafs are the same as v8 for mustangs is this true?
That's what you want. The 94-95 Mustang automatics were AOD-E and we don't need that transmission control in our AOD cars. You want the 5 speed computer.And another thing my eec has the catch code t4mo and yet someone wrote 94 305 5spd on it
If you upgrade to 24lb. injectors and put in the MAF from a 94-95 Mustang Cobra then it should work fine. Otherwise you will need to get it tuned to manage the different MAF.5.0 bird said:I have a question about the 94-95 Cobra ECM. What I'm wondering about is, since a 94-5 GT ecm works in a bird, would a 94-95 Cobra ecm work if I upgrade to 24lb injectors and the ford 70mm MAF? Also those are code J4J1 aren't they?
5.0 bird said:Are you saying that the Cobra uses a different MAF than a GT?
Again, the connector may be the same and the housing may be the same but I wouldn't count on the transfer function in the CV ECM matching the one in the Mustang ECM. It may be fairly close but it's going to suck when you start trying to tune the car and you have to completely tune your baseline transfer function because it's not correct and starts sliding exponentially out f tune for every change you make.icantdrive55 said:The '92 Crown Vic uses the exact same maf as a '94/'95 Mustang GT and Cobra. Might be an easier find and possibly cheaper if buying used. Mine was 20 bucks.
icantdrive55 said:Ok, let me word that differently. If you buy a reman at O'Reilly or Advance or Ford those 3 applications have the same part #.
Here is the Ford # stamped on the sensor F2VZ12B579AARM . That is the number that says how the sensor is calibrated. Just make sure you have that # on it and you have a '94/'95 Mustang mass air sensor.
Mitchell shows the '92 CV having the F2VZ12B579AARM and Alldata shows the '92 as having part # F07Z12B579AARM. Both show the '93/'94 CV having the same sensor as a '94/'95 Mustang gt or cobra.
Mine came from a '92 CV and is stamped F2VZ12B579AARM.
From what I gather some early '92 CV's had an aod and the F0 sensor. With an aod-E the F2 sensor was used.
The sensor is exactly the same but of course the computer is different
