[QUOTE="bigjohnsd, post: 1248850, member: 86475"] There are many Dyno Tuners present at the Sturgis Pirate fest, so many that Dynojet sends their Factory Dyno truck and three experts to handle the troublesome bikes that the normal dynotuners can't get right. The Dynojet Factory truck is set up right next to us. I visited with the three techreps yesterday, they and we weren't too busy in the mid-afternoon, they told me that for the FJR the O2 Sensor should definitely be unplugged when the PC3 is installed, that the unplugged O2 sensor will not and should not set a check engine light, and that if left connected the O2 sensor will cause the ECU to try and correct t the changes the PC3 is trying to make. If anyone has a specific question, PM it to me and I will ask the experts and either PM or Post the answer, if you include a email addressiI'll ask the experts to contact you directly if you'd rather. They were telling me that the OEM stuff on the newest bikes is so good they hardly ever can make more power, they can sometimes solve some lean surge issues, but that improvements by the OEMs has severely cut into their business.
