Default Re: FCM Flow sensor signal

Does the motec have a D to A output (0-5V) to control the flow's sensor sensitivity?
If I understand this correctly, a 0-5 volt signal is used by the FCM to scale the output of the flow sensor. So if I input a regulated (Constant) 5 volts from the ECU, I'm assuming the full flow capability of the sensor would be metered in a linear 0 - 5 volt range?

If this is correct, what is the resolution of the 0 - 5 volt range? 255 points?
