yes uppo, this is a strange one, i checked the serial link at the controller and at the gong board, and the frequency was right on at 1200-1300 hz. i have had trouble with the frequency changing, and doing strange things with other cars, but this is right on. I also went thru every parameter and io setting, and everything was as per the job sheets. one thing a otis guy told me was to clear the PF ram, which i completely forgot about, so i will try that next week.
