Got my PMCR back from TST, and all seems well.
Mark said the timing circuit was dead when he got it. He warmed it up and it came back. Then gave it a reflash and put it in the freezer. Said it was fine coming out of the freezer so I am giving it a try.
He even sent me an updated timing harness and bypass connector, and shipped it all back to me... ... . free of charge! This is on an OLD pmcr, very early serial number.
I can't say enough good about the customer service I received, and all the new options are just plain fun to play with. Kudos to TST!
