That PCM code sucks. On the bright side, any custom tuner you speak with is going to send you a PMT1-based chip unless you specify otherwise.

At least you have a good PCM family (DPC 422).

I believe MRT1 is the same DPC family as the PMT and NVK. Pull the pcm out and check on the tag for the DPC #. If it is then a PMT program will work on it.

yes you are right about the codes on the computer it can be set up with PMT tunes. I have dyno proven PMT1 tunes and will be happy to help any way I can
