PCM stuff....

[T. Barcia]

Hello all,

I tried using PCMCOMM and the circuit on Dave's webpage and got interesting
results.  It never displayed the VIN nor did it display any of the data in
the upper portion of the display, but I did manage to log what it sent and
received and it is pasted below.  Could someone try to tell me what this
means??  It's a 1995 Camaro 3.4L v6.

Thanks.
