speed rule at device level


Hi there - after searching the forums and the blogs, I know that the speed of the vehicle is measured through GPS not the ecm.  BUT...when turning on the buzzer for driver feedback linked directly to the device, where does the speed come from.  We think it would be from ECM since everything else comes from there.  CAn you help?

Hey Laurie,

You would be correct in thinking this. All driver feedback measurements for the vehicle take their data directly from the device and the ECM. One additional thing you might not know is that this will only work properly if the device is on Pro or ProPlus due to being the only plans that gather engine data.

Best Regards,
