GPS Can Bus module.

Inject Speed, longitude, Latitude and Heading in to your Can Bus using this GPS module.

GPS Can Bus speed signal can be added to most ECU's, For the STM Pro ecu it can be used and the data then used for Speed and Gear calculations. You don't have to wire in a VSS signal.

The Pro Displays can use Speed, longitude, Latitude and Heading as part of the logging and that data can then be used to display where you have traveled and all sensor data can be viewed on that trip or race day (Image included of Symmons plains raceway on one of our track days)
