Hi Thoha,
I think that I have the same problem as you describe, see http://www.diydrones.com/forum/topics/accelerometer-calibration-fai...
Do you remember how you solve it?
Calibration always fail.
problem solved, it just need sensor callibration
I think this is the earth's gravity that apply continuously to z axis of the MPU-6000 accelerometer.
If the MPU-6000 is ranged for +-4G the output value for -1G is -8192.
Also your sensor is not absolutely horizontal, for this, you read a slightly less value than -8192 and a value of 61 on y axis.

Is this normal or something wrong with the accelerometer Z axis?
