Here is some amazing data coming off a medium RPM ITB motor. This motor makes peak HP at 7400 RPM. On the bottom left of these plots is where the motor is operating in Speed Density mode. Fueling is very much a function MAP and RPM. As the throttle position rolls up thru about 25%, the motors need for fuel and personality completely changes.

This data is filtered to only show 3700 RPM and higher. Harleys operate almost entirely in the lower left portion of this example where Speed Density tuning works just fine.
Here is what the data looks like when you only look at 6500 to 6600 RPM. Everything else is filtered out.

A typical Harley looks more like this when running Target Tune. Just for the record, most turbo motors look just like this.

Sorry you aren't learning anything but I am not taking responsibility for that. It could be because there really isn't much to learn about screen shots with out the data to go with it? Sounds like Andy need to step up his game.

No, I don't. I have mentioned that it can be filtered to show whatever you want, and that having a pretty pic means nothing to how the bike actually runs. The data that we are looking at is indicated data, and other data channels can be used to determine if it indicated wrong or if what we are seeing is really what is going on.
A good example of this just came up in the Vision sticky.

Post 4643 shows how one data channel, in this case is accel enrichment, can be validated by looking at other channels.
But if you want some data. I will gladly post some up for you. I figured you had a bunch with all the HD tuning you claim to do. I figured you could show screen shots from the beginning to the end of the tune. Showing 4-5 screen shots along the way of it getting better and better. Explaining what info you are getting from the scatter plots and how this info is helping you in changing the calibration that made it better. Kind of like what people post all the time when they are putting up their collected data and the calibrations that go along with it.
Stand by.
