new ecm software do i need to relern crank position sensor?
I did put in the latest software in my 2005 c6 with my tech2.
But do i need to relern crank position sensor after this? i did not change out the ecm/pmm only uppgraded the software.

If you changed out ECM and did the initial firmware flash install (with the new firmware) to load it, you will need to go through the relearns instead.
To note, if your firmware was not updated, may want to make sure that the firmware for the radio does not need to be updated as well. This is not done through the tech II, but a DVD that is loaded into the radio instead.
