Discussion and questions related to the course Reflashing

You mentioned a flash counter the dealership may use if still under warranty and engine damaged occurred from a modified PCM. I'm using HP Tuners VCM scanner, where would I find the counter on a GM 2002 PCM? And does the PCM have a reflash lifespan? How does real time RTT show/effect the counter?
