question about cobra computer and maf sensor
- Thread starter gmak
- Start date
Um... well, I would presume they'd have different part numbers on them, since they're different parts, but to my knowledge, they never put numbers on the computer or mass air sensor to correspond to one other? The 94-95 Cobra and GT used the same MAF, it was the tune in the computer that allowed it to use either the 19 or 24lb injectors. Welcome to StangNet btw 
let me rephrase the question. The computer I bought is for a 93 cobra. I have been told I need the cobra mass air sensor. so I bought one. after looking on the internet for info and such, it seems the cobra mass air no. shouild be f1sf 12b519 aa. but the number on mine is e9zf 12b519 aa. the aluminum casting is from a cobra, but I'm wondering if someone switched the electronics off the cobra casting. Does this matter? I have read I need the cobra maf for the cobra computer to work properly.
although the computer is for a 93, I am using it in a 95 gt

This could get confusing but I'll try to keep it simple.
First of all from this point on, I'll be talking about a 94-95 Stang.
You already have a Cobra maf cause the Cobra & GT used the very same maf as Matt has said in the above post.
I may not be understanding your plan but to me it seems like you want to use or copy the pcm and maf setup on the Cobra for your GT. If that is so, you need the 94-95 Cobra pcm with the Catch Code of J4J1. You can use your maf as again, it is the very same maf as the Cobra used.
You will however need to use 24lb injectors with that Cobra pcm.
So with the pcm, your original GT maf, and some 24lb inj's you will have the exact same setup for your GT as the 94-95 Cobras.
Now I'm gonna be talking about a 93 Stang.
You got the pcm from a 93 Cobra and that changes things big time.
Totally different pcm strategy so the only way to make that pcm work with your Stang is to do a change to the pcm harness.
I'm not sure ...... but you may not be able to use your original maf since you are now trying to use a pcm that does not belong in your car. If the maf on the 93 Cobra is the same as the maf on a 94-95 GT then you might be able to pull it off.
If I was you, I'd see if you can exchange the Fox Cobra pcm for the correct J4J1 Cobra pcm.

Thank you for your support
I really don't know as much as you guys seem to think I do when you compare me to many others that are out there.
You take a guy like Don 95Vert.
He has so much knowledge about all year model Stangs and I on the other hand have only focused on the 94-95 Stangs.
When you look at it that way .............................
That "world" Matt talked about becomes ......
pretty small An old saying comes to mind now that I think more about Matt's post
that just may very well describe me and my ability.

I plugged the the 93 cobra computer in the car. and test ran it. no check engine light. car started and idled great. But it ran extremely rich. The power was off when driven hard. The car still has the 19lb injectors, and the 95 maf. I thought maybe the rich running was a mismatched maf, pcm reading the reference, but off for calibrating. What mods may I need to the 95 harness?
