That looks like the brand Authority IIRC?
I know the 964 AFM is the same as the C3.2 but that is comparing apples to oranges. It should work as long as the chip is for a 3.2.

It looks a lot like the Autothority unit that I have but the control box is different. I'm guessing Steve Wong could modify a new chip for it. The stock 3.2 ECU chip will work but not very well. Let me know if you want a picture for comparison.

Now that I look closer the controller looks the same just a different label. I think AutoThority closed shop. Check with Performance since they used to handle them. Mine is about 20 years old. The only problem I had was about 15 years ago when the potentiometer started giving me problems. Cost only $90 to replace. Very happy with it.

Good question. I did a search and didn't come up with anything. I don't think its a part you need to keep in the garage. Mine lasted a long time and it was probably the Texas heat that did it in. I'd check with our host and maybe a garage that has race experience.
