I'm assuming you are using either the 'Tuner' or 'Winflash' program from Tuner C.A.T.S. site to read and write (program) the .bin file that you saved to your computer? Their site does not make it clear if you also need the '$EE Definition File' along with the 'Winflash program' to read and write to the PCM. You do with the 'Tuner program' and I'm sure you will need it to save the original .bin file from the old PCM.
You can use the 'Tuner' and 'Winflash' programmers free for 30 days, but you have to buy the appropriate 'Definition' file @ $19.99.
I have a '94 A4 original .bin file if you need it. Its the same as the '95 A4. PM me if you need the .bin file.

You say you read the original PCM's file. Did you save it to your hard drive as a .bin file? If so, you may have to try more than once to load it onto the new PCM if you are using a USB cable. Some times the USB cable does not sync correctly with a computer's USB port and you will have to try until it does show its communicating.

Yes, I purchased both the tuner program and the definition file. I read and saved the file with the tuner program. Then tried to write the old file to the new computer. I tried several times to connect, turned off my virus software and firewall, but no luck. I have another 95 BIN file I found online in case I couldn't read this one, thanks for your offer though.

Are you flashing it installed in the car, and if so did the new computer come from a Y body or is it perhaps from an F or B? If it's from an F or B my experience is that you have to bench flash it.

Can you successfully read the new computer with tunercat? Or scan it with datamaster? Don't go trying to flash it if you haven't established that you can talk to it or you'll end up with a doorstop.

It is for a Y body. Its a remanufactured ACDelco replacement.

I emailed Tunercat's tech email over the weekend and received a reply today. They replied as follows:
If the PCM is new and never been programmed then you'll probably have to have the dealer program it the first time. Then you should be able to read and program the PCM without any problem.
