Correct, the map represents the PCIII "map" which is overlayed on the stock ECU base map that it reverts to when you unplug the O2 sensor, which would otherwise do it's best to undo the changes and tune to sanitized for our protection settings. We don't want that

In short, the bike needs more fuel in the lean EPA test zone lower rpms, especially after mods, and the top end is trimmed of fuel a bit as it is a bit rich, even with mods. Same story with pretty much any bike out there. You can see the biggest fuel add is at small throttle settings at cruising rpm.

The thing I am finding is the "accelerator pump" feature on the PCIII really sharpens throttle response. It gives a little extra squirt for short duration in response to changes in the throttle. I have mine set pretty "insensitive" but with a healthy squirt. I think this helps keep fuel economy reasonable with normal throttle modulation, but the thing jumps when twisted more aggressively

I am hoping the smoother map will be an improvement or, at least, not be noticeable and perhaps help with economy a bit. There is some satisfaction in it, even if I can't tell the difference
