Ok, so I got the VCM enhancement to use RTT for HP Tuners. How do you write the new OS into your PCM? They help file starts assuming you're already done that (unless I'm missing something, which is entirely possible). I'm sure it's very easy and probably addressed somewhere, but I seem to be missing it...Thanks

Thank you. As I suspected, I was just missing it...
