I just purchased a used vibe and had the board replaced also just put in a new Duracell battery. I am shooting with CO2 and am having an issue. I have the board set in tournament mode so it only shoots semi-auto. Everyone once and a while it will shoot a three ball burst. If I shoot slow and steady it will shoot semi-auto if I pick up the pace and shoot quickly it will all of a sudden shot multiple times. Anyone have any suggestions on what might be causing this.
What you're describing sounds more like psp ramping mode than anything else. First 3 pulls are semi then 3 shot burst. Most board software are the same, but try changing the mode one more time. Usually 3 blinks is semi and 2 is ramping.
