I havent used my PP yet, but I believe the KDW needs to be set lower or higher, depending on how hard PP engages. If it sets real hard or has a hard time picking up the speed, then I would mess with it. Have you tried PP yet at the factory setting?
When I killed my 4 blade prop once and had to use my 3 blade spare I found that PP was a bit sluggish in getting back up to speed after a hard pull. I set the Kdw higher to compensate. Before that I had left it at the default setting. I've never gotten a jerky pull before but I imagine I might if I had a power prop run from a higher HP engine. In that scenario you may have to set Kdw lower. You give your boat specs when you order PP so theoretically the module you get should already take into account your horsepower and boat type. Prop is probably the major variable unless you bought the PP off of craigslist from someone who had it on a different boat.
Actually this was on my list to ask. Got a friend with a Calabria with PP. It really struggles to keep up with a wakeboard and over/under corrects pretty badly. Can you guys tell me the base level settings? Right now stock ballast and prop. I think there are like 2 or 3 numbers he has to adjust. Since we are bigger guys, I would like to tighten up the calibration a bunch.
