| I ask a friend who has gone threw power commander school several times about the un plugging of 02 sensors and this is what he had to say.
1. Any Power Commander overrides the factory O2 sensors. They can be left plugged in or unplugged but if you do not plug the ?eliminator wire? back in to the factory harness a trouble code will pop up on the dash. If you leave them plugged in, they are not functioning once you have installed the Power Commander.
2. The Power Commander V only works with the O2 sensors provided with their Auto Tune Kit
which is an additional $369.95. The P.C. V will not work with factory O2 sensors.
3. In terms of getting ?more power?, most tuners (mechanics) will create a map for a bike based on all it?s specific features. The O2 sensors provide a ?point of reference? for the ECM to calibrate for the ?perfect air fuel ratio?. With this in mind, ?O2 sensors would definitely be the way to go? for achieving maximum performance (most power and run ability) on the street due to constant condition changes.
4. Most tuners can build a map, on the dyno for a customer by manipulating different fuel cells.
Since they are doing this ?manually?, there is no need for O2 sensors which is why you will find some tuners not using them and achieving ?big numbers?. By doing this they can achieve a ?maximum horsepower number? which is usually what customers are after.
Ultimately any good tuner will use an O2 sensor (at least 1) to get a reading on what the bike
is putting out for an A.F.R. Once they get the reading, they will remove it and lock in the
desired fuel cell readings to create a map and send the customer on their way. |
