Hello,

I bought HPtuners Suite a week ago. Also got Greg Banish DVD. Have studied a few days last week and then worked on my c5 Z06 (Ls3 525hp) this weekend. I had great success and found a few issues and car is running better. However I find myself continually wondering what the GM PCM operating system logic is. I see that we have all these parameters to mess with, of which soome are simple and others less clear. It seems like a guessing game knowing what the PCM logic is, for example what algorithm it uses for PID loops, Dynamic Airflow, Spark Retard, etc, etc. Feels a bit like a black box. Is there any education manterial out there. My PCM is P59 GM Gen 3 with 1281056 Operating System.

Thanks
