Quick Shifter Randomly Cutting Ignition and Not Working

austinrseevers@gmail.com · November 2020

I have a 2016 FZ09 with the Quick Shifter installed and programed by my dyno tuner. The quick shifter was working just fine at first then randomly started giving me issues. When I go to upshift the quick shifter does nothing. Although when I first give it throttle in some gears (mostly first and second) it will cut ignition as if I hit the quick shifter even though my foot is completely off the shifter. Anyone have any ideas??

The QS and Harness I have:

With this kit and your flashed ECU you can up-shift without letting off the throttle or pulling the clutch! This kit includes everything you will need to utilize your FTecu flashed ECU’s Quickshifter Input.

Had the same issue. As soon as I went pass the minimum RPM for QS engaging, the engine would sometimes cut, or QS would not engage if I did not use first the clutch to change gear. It was only happening after pressure washing, so I just put some silicone near the electrical connection of the QS to seal it. Seems have fixed the issue.
