Data Logging  is a tool available with your HotWire 2.0 on both the PC and Android versions of the software. You are able to record parameters such as ESC Temperature, Motor Temperature, Battery Voltage, Throttle Position, and motor RPM at various resolutions and sample rates, all of which determine how long your captured data stream can be. Recording less parameters at lower sample rates will increase the amount of data the ESC can store onboard, while recording all the parameters at higher sample rates will use up memory more quickly. Once the ESC data storage is full, it will stop recording and you will need to clear it on the ESC or through the HotWire 2.0 in the data logging interface.


To clear the ESC data log storage, simply press and hold the INCR button until you hear two quick chimes, at which time you can release the button and the ESC will re-arm and be ready to drive. You can also set the Remote Data Erase via the HotWire 2.0 which allows you to hold brake for 5 seconds, clearing the data memory. Note that it is now actively recording data until you switch the power off. Each time power is cycled, the ESC creates save points in the data called a Run. You can have multiple runs saved in the data log storage simultaneously, until it reaches max capacity. This feature is great for making a quick change and recording the data for easy comparison later.
