All axes output wrong reading

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Initialize IMU level
2. Slowly turn 90 in roll
3. Return to horizontal orientation.
4. Slowly turn -90 in roll
5. Return to horizontal orientation.
6. Repeat for pitch and yaw (yaw rotate 360 in 90 deg increments)

What is the expected output? What do you see instead?

Each axis output should correspond to the number of degrees turned
Roll reading: actual roll: - 90 deg -> RLL output: - 120
                          +  90 deg -> RLL output: + 120
Pitch reading: actual pitch: -90 deg -> PCH output: -50
                             +90 deg -> PCH output: +50
Yaw reading: actual yaw:  0 deg -> YAW output: 180
                          90 deg -> YAW output: 108
                          180 deg -> YAW output: 45
                          270 deg -> YAW output: -40
                          360 deg -> YAW output: -180

What version of the product are you using? On what operating system?
ArduIMU V3
firmware version 1.9

Same with my try. I got ArduIMU v3 x=90 degree, but showing 120 as output.
tested with Kalman filter (new download) without any success.
Any idea, why output is higher than it is?
Thanks for any input!
