What?
wait, when do you see these knock retards? all the time or just at WOT like in the shift points?
The KR PID has never worked for us with torque. I even exchanged a couple of emails with the developer and sent him a couple of debug things, but it never worked.
Check that you've also chosen the correct predefined additional PIDs for GM in the options menu.
See if you can save some logs and post it so we can see what you're looking at.
well have the latest version, so I tried to do the process described above but tried to reainstall the app isntead, but no KR shows up and no other extended PIDs such as the transmission stuff.
It's ok though I still got the powrtuner, I only use torque to check if the trims are still in range and any SES codes that show up when I'm too lazy to plug the laptop.
