	accelX = Math.Sign(accelX) * (Math.Abs(accelX) - drift[0]);
	accelX = Math.Sign(accelY) * (Math.Abs(accelY) - drift[1]);
	accelX = Math.Sign(accelZ) * (Math.Abs(accelZ) - drift[2]);
	accelX = Math.Sign(gyroX) * (Math.Abs(gyroX) - drift[3]);
	accelX = Math.Sign(gyroY) * (Math.Abs(gyroY) - drift[4]);
	accelX = Math.Sign(gyroZ) * (Math.Abs(gyroZ) - drift[5]);

These lines only set accelX.
