So 2007 1200 O2 sensors. Yes or no? Do we have a definative answer as to whether best results are achieved with running these or eliminating these? I have a PCIII fitted.

 

They're simply another tool to use in the tuning process...fewer tools usually means a more mediocre finish.

 

Unless you are using a tuner which allows access to the ECM's AFR/Lambda table you will need to bypass the O2 sensors. If you have a PC III you need to use the O2 sensor eliminators as listed in the instructions otherwise the ECM will force closed loop and essentially undo any tuning changes you have made and adjust the mixture back to 14.6:1 AFR and it will likely also throw P0131/151 codes. Also note that the factory nb02 sensors are only helpful when requesting a mixture of 14.6:1 (+/-.5)

 

Jamie,

If I go with a PC V for my '09 RK (with O2 sensors) should I go with the one with auto-tune or go with the PC V without and have a dyno guy finetune it at his shop?

Thanks

 

Both setups will provide a great tune when done properly. I would base my decision off of what is available for a base map, whether you or a trained dyno tech is doing the tuning, and what you are planning for mods for your bike either now or down the road.

 

Big thanks Jamie. I am just about to fit some new Hooker Rebel pipes and can't find a map anywhere. Have you guys done a map for this config?
