ADXL345 - too noisy

How does the measured noise compare with what the data sheet indicate?

Great question - I'm not sure how long it takes to come up to temperature. We'll try to determine that - thanks for the input. Maybe we can read the temperate sensor on the gyro and compensate. The noise is much more than the data sheets indicates but we are pretty sure most of it is real. The sensor is fine, the robot is just a nasty mechanical environment.
