2006 R6 FTECU Quickshift
Had my ECU flashed by 2 Wheel Dynoworks recently, and sprung for the FTECU quickshifter from them. Installation was pretty easy, no issues there.
The lower gears (1, 2, 3) all shift consistently with no problem. Occasionally 4th won't work, sometimes 5th, and now sometimes 6th. It is not related to RPM, it does it at all RPM ranges, and at all throttle openings. I have put an RF choke on the QS harness in hopes it was an interference issue, but no luck. The shift arms are parallel, so the linkage arm length is correct.
I have been reading about the newer QS problems people have been having, is this common on the older 2006 as well?
