Can't get this thing to read voltage for the life of me. Am I doing something wrong or does it just not work?
2002 LB7 - DSP PID, not valid?

make sure you have the right ECM selected and validate the pids

Also you do have a DSP5 OS in it correct? If you have a DSP2 it will not show up. And I don't know why, but for LB7's I have found I have to validate the PIDS everytime regardless.

I ended up figuring it out. For whatever reason, the V2 wouldn't monitor just the DSP voltage. After some googling, I tried selecting multiple PIDs and it worked like a charm. Everything was functional tune and OS wise, I believe that the pin connection at the PCM was poor. The voltage seemed glitchy. Swapped out DSPs and it worked perfectly. Also seemed like I had to re-boot the V2 to get it to connect to the scan tool properly.
