RPM not supported

[AkSSS]

I just built a 408 for my 03 Silverado. I am trying to do a crank relearn. For some reason the scanner will not pickup up my engines rpm's. The tach is working. If I clear the vehicle out of the scanner and reload the scanner. The Pid is working until I connect with the pickup. I also tried removing the pid that is not supported and adding it back in. It is not even in the PID list to add once I am connected to the truck.

I also just updated my windows program and my HPT trying to make sure everything is current.

Any ideas?
Thanks

Anyone? Ever experienced this? Truck is running but need to do the Crank Relearn.

Try this:
Close all programs
open my documents-hptuners-vcm scanner-vehicles folder and delete all of the files within it
close the folder
reopen vcm scanner
this will force the software to repoll the pcm for the available pids.
