Problems with data logging

[mparker]

I am having trouble picking of 3 Pids when i data log. I can't pick up main injector fuel flow rate, main injector pules timing, and turbo boost pressure. I have them all selected before i hook up to the truck but those 3 stay with a red X throw them.
My truck is a 06 lbz.

Try validating the PIDs after you connect to your trucks ECM in the scan tool. On your laptop go to Info > Validate PIDs.

Thanks!! That was the step I was missing.
