Our tach input cable connects a tach signal from your vehicle’s ignition system to the digital tach input on the Race-Keeper system. The tach data signal should be a clean square wave, nominally 0-5v.

The Race-Keeper HE cable has a bare wire for connection to tach signal on the vehicle and a locking sensor input connector for connection to the Race-Keeper HE’s sensor input.

Race-Keeper Comparo manages calibration of the tach input signal. Once an outing has been recorded with the tach cable connected, the tach data will appear as an available data channel in Race-Keeper Comparo, which you can calibrate by right-clicking on the RPM channel name and selecting the number of pulses per two engine revolutions.

Note – In order to connect this cable, you will require a “HE/Black Analog Sensor Loom”

We know that your time on track is limited, but so is the time available between sessions, during which you have to review your video/data, along with a whole host of other things. That is why we have made our video data analysis software so simple to use.

Although we believe Comparo HD is the simplest video data logging software on the market, to some we appreciate it may appear daunting at first glance, due to all the text, graphs and buttons. That is why we actively encourage you to download a copy of Comparo HD for free, along with some sample video/data and have a go at comparing laps and analysing data for yourself.

Comparo HD is Race-Keepers video data analysis software which plays synchronized video alongside course map and data traces, including speed, lap number, lap time, G forces, as well as any other data streams available via OBD-II, ECU/CAN or from Analog/Digital sensors.

It presents all of this information in a single, combined view so that you can instantly start analyzing your ontrack performance straight away. Data and video is automatically syncronized so there is no unnecessary setup or configuring that is required before you can playback your outing.
