so i put my MMS PCM in this morning, followed the instructions on PFYC for the re-learn. Did it once, and it didnt work. im in the middle of the second attempt , we will see what happens. should i be doing something in addition to the steps on PFYC, does the digital HP PCM differ from the MMS PCM in terms of re-learn procedure?

Nope, it doesn't matter who it is from, the security re-learn procedure is the same. Sometimes you have to do it more than once. May take several tries before it cycles through the codes and lands on the right one that will start it.
