@GSchmid your final settings are pretty close to what I have mine set to. I have ball 1 at 45, ball3 at 25, and ball 4 to exit at 31. What engine/ boat do you have? I have a 1994 Ski Nautique with the 240 HP engine(351 FORD). I am thinking your settings may work on my boat. The settings I have corrected the surge, but still trying to get the times dialed in closer, but they are still within RC tolerance.
