My good friend purchased the newest version of stargazer 3 event this year for his 1994 prostar, but we have not been able to get it work well at all. It will put you in the course way hot if you don't back the speed way off. I have to base everything off of my RPM's if I want to get the skier going through the fifties at the right speed. The system will take over and then it will be all of over the place I would say it varies by about two miles per hour on average and usually doesn't really kick in until the skier is around one ball already. sometimes the system will loose GPS and just completely shut the cruise control off. we have calibrated RPM's, We let it go through its auto calibration, and mapped the course. Anyone have any suggestions I would greatly appreciate it.
