    Confused. Assuming that your new TCM has a different OS than your dead TCM, SPS is the only way to change the file OS in these TCM's, to convert it to the file you need. Unless I missed something...

    Correct Ross. And this was true beginning in 2011 LML E86, where the BCM needed to be detected. It got worse for 2016 ECM's. So far, have been unable to factory program any USED 2016 ecm using GM....
