Has anyone used a power commanderIII with the Knightrider IED's and the stock O2 sensors? If I understand correctly, all these can be used together. PCIII for performance, the o2 sensors for highway fuel milage and the ied's to help it run cooler when in closed loop made(highway). Anyone try this?

 

As I have an older injected bike I have not done the full research on this yet. My understanding is that the EFI computer on the bike will run in Closed LOOP mode running on the sensors until some point in the power band when it then switches to OPEN Loop mode and runs straight off the Original HD Map. So you could set up the PCIII with a 0 table upto say 50% throttle and 2500rpm and then map out the remainder of the power spectum.

THe exact point the EFI switches is known by someone here on the board. Hopefully they chime in. If you do this I would not even run the knightriders because that would richen up the whole range.

The advantage of the PCIII also is the Power valve fuel shot. So you can tune in a extra shot of fuel when you start accelerating.

 

Did you mean the accelerator pump feature ?? I am under the impression that that feature is designed more for sport bikes and is basically worthless for HDs. I get this from some of the seasoned tuners on this forum.
