"Speed and distance options" for Dash 4 Pro

Postby CharlesElliott » Mon Sep 03, 2018 6:28 pm

There's nothing about this menu option in the knowledge base - can anyone help with the details?

Display speed from combining acceleration and GPS data doesn't really make sense to me on a Dash 4 given that it has no sensors and gets everything from the serial feed in the DL1?

What is 'reset distance on lap markers' there to achieve?

Hello Charles,

These options are only relevant when our DASH4PRO is connected to our SPEEDBOX product. They have no affect when using the DASH4PRO with our DL1 / RT LIVE data loggers.

Additionally, if the second speed option is selected "processed speed" is used instead of "GPS speed" when available. If the distance option is selected, the distance displayed on the DASH4PRO is reset to zero as a lap marker is passed.

Another question linked, how to use the "wheel speed" variable in the DAS4PRO?
There is no way to define the link between a frequency input and the wheel speed (as defined in the car options with analysis).
There is also no way to do it directly in the DL1 configuration tool (mapping).
Actually, I had to use a rare "user defined variable" for it but I don't understand the meaning of the "wheel speed" variable in the DASH4.

You are correct, wheel speed is not helpful here and a user defined equation is the best way to handle this.
