None of the directions say much about setting up and calibrating an AIM MXL2 dash. Are you supposed to have the dash perfectly vertical or can you have a slant to it so you can see the screen better. If you have the dash tilted 10 to 15 degrees will the tilt be taken into account for the 3 axis G meter and Gyros when doing the auto calibrate for each axis? My guess is that you can have it angled because it doesn't say you shouldn't.

Since the dash has roll, pitch and yaw sensors (X, Y and Z) as well as long, lat and vertical accelerometers, you MUST use the calibration feature on the right tab of the config. Auto calibrate and the accelerometers zero fine. Of course you can have it angled.

This is EXACTLY the same calibration procedure as the EVO 4...

The closer to plumb and perpendicular to the car's longitudinal axis the better. If you're a couple of degrees off, it's nothing to worry about. If you were 45* off, you would want to find a better way to mount things!

The calibration corrects for the dash not being perfectly vertical and corrects through the other axis. You should be all set once you do the calibration (which should be a part of your morning track routine).

I can tell you from this past weekend that the default filtering is insufficient. I haven't played with it more since I was preoccupied with unsuccessfully trying to get gear calculation to work. I wish I could just enter a simple table.
