Their is a mismatch  between the MPU6000 documentation and the arduimu source about the

Scale Range of the Accelerometer.

The output from the arduimu software looks good !

I have another MPU6050 from Drotek

http://www.drotek.fr/shop/en/42-mpu6050-gyro-accelerometer.html

and the output from this one match the documentation. Then the doc is not totally wrong.

Any idea why the MPU6000 inside the ArduIMU V3 don't match the specs ?

Here are my references

Looking at MPU6000.ino I see

MPU6000_SPI_write(MPUREG_ACCEL_CONFIG,0x08);            // Accel scale 4g (4096LSB/g)

0x08 => AFS_SEL=1 and then this is the "4g" range

But in the documentation (see attached picture), AFS_SEL=1 means 8192LSB/g, but the output from the ArduIMU V3 match the 4096LSB/g scale !

Any idea why two similar chipset with the same config return value in two different range ?
