I thought you can adjust the settings manually?
So I was taking a look at the maps to make sense...yeh, I'm that boring.
Can someone explain to me why the engine is running that rich at 0 throttle? Is this to smoothen the engine on downshifting?
Looking at the tables, there is not much addition of fuel at 100% throttle. Why is full throttle so lean?
Does it make adjustments to the present ecu that is connected?Keep in mind the adjustments on the power commander maps are not absolute values. They are adjustments to the factory mapping.
If there is a richer adjustments at 0% throttle, it may be an effort to eliminate the after-fire that can occur with aftermarket pipes during deceleration.
The lean adjustments are to correct a situation where the factory mapping turns out to be too rich for the new intake/exhaust combination. Each bike will act differently with slight changes to pipes and intakes (really any changes to volumetric efficiency), and the adjustment maps are there to correct that.

What if the ecu already on the bike was tuned?

The power commander does not care what ECU is in place, or what map is in that ECU. All it does is compare throttle position to engine speed and adjust fuel (and sometimes ignition timing depending on model) according to what is in the table installed on the power commander. If you have changed the ECU map, the power commander will still adjust the fuel/ignition settings, but they will most probably be incorrect. If the ECU was already tuned correctly there is no point in using the power commander for air/fuel corrections. If you need it for something else, just install a "zero map" (all zeros) and continue using it for whatever other functions you are using it for.
Would you happen to know why there are high values at 0% throttle table? Is that to smoothen throttle or reduce backfire?If you were working with a stock unmodified ECU, you could continue playing with the power commander to your heart's content. However, in this case you don't really know where you are starting off. The base power commander maps are made for an unmodified ECU, as this doesn't really apply in your case you need to start from scratch. This will involve an experienced tuner and a dyno. Ideally if you can find someone with the same software that was used to reflash the ECU, you might be able to do away with the need for a power commander altogether, or have them revert it to stock.
