ok. one last question. with my pc5 the o2 sensor is unplugged. does the o2 sensor need to be plugged in with your flashed ecu?
Flashing your ECU will remove the factory restrictions including the ignition timing restrictions which will unleash as much as 13 horsepower form your stock engine.ECU flashing offers many more features then a piggyback system such as a power Commander and costs a lot less.Here is a list of features available with our ECU Flash Service:
Optimize fuel curves across all gear ( same as a Power Commander)
Optimize ignition curves across all gears (remove RPM & throttle based ignition restrictions)
Raise RPM limiter
Adjust idle speed
Adjust in gear idle speed
Disable pair valve
Disable steering damper
Disable O2 sensor
Disable exhaust valve
Reset radiator fan turn on/off temperature (205 / 195 )

I realize fuel economy is directly related to how heavy handed the rider is, but is there a rough estimate of how much the fuel economy decreases with the removal of the O2 sensor?The main function of the O2 sensor is to improve fuel economy.For that reason Dynojet recommends you remove it to improve power output.We recommend removing it if you are interested in increasing the power output and not so concerned with fuel economy.
This statement makes my head hurt. Power output and fuel economy are different sides of the same coin. If riding behavior doesn't change I don't see how any tune that increases power will hurt fuel economy (unless you are running rich on purpose for cooling).The main function of the O2 sensor is to improve fuel economy.For that reason Dynojet recommends you remove it to improve power output.We recommend removing it if you are interested in increasing the power output and not so concerned with fuel economy.
So remove the O2 sensor to get more power while riding at a constant speed? Seems like a waste of time.The ecu monitors the throttle position and when it sees that your holding the throttle steady it switches into close loop and reads the O2 sensor output and leans out the fuel mixture to achieve better gas mileage.The moment the ecu sees you move the throttle it switches back to open loop and disregards the O 2 senor.Keeping the O2 sensor on your street bike will help you get 1-2 more miles per gallon.

Right, but who rides at a constant speed on the track? If the O2 sensor is ignored when you are manipulating the throttle, removing the O2 sensor should have no real effect for a track rider. There seems to be no reason to actually remove it from a performance perspective.For people who say use there bike to commute to work everyday they might want to keep the O2 sensor so they can get the best gas mileage and save some money on fuel cost. Thanks Dan
No USB kit for sale yet but bin is. I assume once it is available Dan can get them flashed?Interesting read.
Have the 2017 ECU's been evaluated for flashing/programming yet?
