I suggest you take your own advice. It states any OBDI PCM (because they’re the same), with a program from a ‘95 to handle the PWM TCC.

The only difference in OBDI PCMs is between Corvette and non-Corvette (the Corvette ones added additional silicon related to OBDII testing). The year does not matter, and since he doesn’t care about the OBDII stuff, neither does Corvette vs non-Corvette.

Why would he need the pwm trans control?

You're right, he wouldn't--it's only an issue on the auto trans. So actually he can do whatever, good point. Even less of a reason to be picky about 94/95.
