Tunercat connection issues

I have a 95 z28 that has the obd1 computer, but an obd2 connector from the factory. When ever I try to do flashread with tuner cat, the com port will not open. We use the same program on a 91 with no problems, and a 91 vette as well. I've tried it in DOS and windows with no luck. Why can't the laptop communicate with the pcm?

Are you sure your cable for the 95 is good? I had the same problem and it turned out I had the ground wire soldered incorrectly in my homemade cable. Good luck.
