My 06 sierra has problems with the ecm, I know when a new one gets put in it must be programmed, can I do that with hptuners? If so how? I have a used ecm from an 05 with the same drivetrain, just need to know what to do before putting it in

Read 06 PCM. Write entire 06 file to 05 PCM. You will have to do the 30 minute VATS relearn. You will also have to license the new PCM with 2 credits. With HPT you always have to have a license for the file you are writing and the the file that is in the PCM. Usually they are the same but in your case they are different.You can not run a 06 ETC on a 05 calibration.
There can be multiple different segments in different 06 calibrations. If you want everything to be correct for your particular vehicle you need to flash it with the correct calibration with all the correct segments for your VIN.
