The P75 and PR4/P74 programs are identical enough to not worry about. There are very minor differences to their circuit boards but the base calibrations are virtually identical.

Not as far as I know. It shouldn't care any more or less than any other OBD1 Honda Civic/Teg ECU, they are all one big happy family of (mostly shared) ECU code and hardware. Using a P74 or P75 should give the same results, and any minor differences in what engine hardware faults it looks for (or doesn't look for) should be easy to change in most tuning programs.. PR4/P74/P75 really are pretty interchangeable.
