10 useless MRTs was pretty stressful. I did get my order in, so now I just have to wait I guess. I sold MRTs for a while and apparently I was my best customer. I had one in every car my family raced. I don't like having to upgrade PTXs, but MyLaps/AMB isn't required to make sure their competition works on/with their timing systems. I sent an email off to Terry, but he said his company is still working on a solution. They currently do not have one. I felt it was better to not wait for new MRTs to come out as that may never happen.
