I have version 9 of Perfect Pass Stargazer 3 event. Has anyone run into where it surges while pulling a skier in the course? I checked all the linkage tests and everything came out okay, and when running a timing check with no skier the numbers come out okay. I have been adusting the ball 1 background settings which is helping, but it will take me a few more times to dial it in. I have a 240 hp carbureted engine, and a 1:1 tranny. If anyone out there has run into the same thing, were you able to solve it, and how did you do it? Perfect pass has been very helpful, but I want to see if anyone else ran into the same thing. I want to get it dialed in so I can add zbox. Any idea if Zbox would solve it?
