Using the Rev Burner with a speedometer
Starting with SimDash v1.1 the Rev Burner can be used to drive an electronic speedometer. In order to do that, the firmware of the board but be upgraded with the special version available in the Download page. The new firmware must be downloaded and transferred into the board following these simple instructions.
The original firmware is always available from the Download page, in case you decide to use your Rev Burner with a rev counter, as usual.
Only electronic speedometers are supported. Electronic speedometers receive a series of electric pulses whose frequency corresponds to the speed of the car. The number of pulses received for every kilometre or mile is a characteristic of the speedometer, and this value can be fixed or variable. The type of signal generated by the Rev Burner is a square wave at 12V, whose frequency increases with the speed.
