O2 sensor

New to the site, Sold my KTM and got a 1000K6 back in November had the stumble, got the TBS done (the 3500 RPM issue it is better) but have a general power issue (vibration) under hard acceleration. Was told they checked the TPS, but I checked it after talking to a buddy with a 1000K2 and it is out of wack and plan to do this this weekend.

Anyway my question is with the PCIIIusb I purchased. Reviewing the PC web site and after an email from PC they recommended that I disable the O2 sensor so it will not try to counteract the FI adjustments made by the PCIII in closed loop operation has anyone done this and if this is done will I get a FI fault code from the ECM on the digital readout, the 2002 tech manual on this site says that the C44 O2 sensor fault is not applicable (actually the words are "except for US") for the US models ?

Does anyone know at what PRM/throttle position does the system go from closed to open loop?

I got the PCIII because I plan to put some Loe Vince cans on the Strom later.

I have ordered the 2006 manual at the stealer, which it appears is the 02 book with a suppliment for 06 (as you can not buy the suppliment by itself) it looks like the ECM connectors used on the K5 and K6 models are different than the K2-K4 models, I did not want to trust a jpg image from PC on what wire to attemt to remove from the ECM connector

Does any one have experience in removing this wire? I pulled the connector from the ECM and it is reather delicate so maybe I will remove wire from sensor. I have a lot experience working with military cables and connectors but looking at the connector it is not readily apperaent on how to remove wire.

Are you talking about removing the wire that feeds the oxygen sensor on a US bike? If so, you don't need to do anything. US bikes don't have an oxygen sensor.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014+ DL1000s. Wee = 2004-2011 DL650s. Glee = 2012+ DL650s

California emisions thing

That is what was confusing here, I have not taken the bottom of the bike apart to get to the exhaust pipes so was not sure a sensor was there but PC told me to disable it, thought maybe it was a California emisions thing.
