I'm trying to scan the PCM in a 2019 ZR-1. I can only read a very limited about of PIDs when I try to add channels. For comparison, I can read far more data from the E38 in a 2012 Z06.
I know there is more data coming over the DLC because one of my sources is a high-level engineer at GM who worked on the LT5 engine development and he told me the PCM sends a lot more data than what I can read with PCM Scanner.
Can anyone give me an idea about what the problem might be?
