With this cable you have the possibility to record and log the speed of your engine as well as the throttle valve or carburetor slide position with MD-Lambda-View.

 The connection for the speed measurement (yellow cable) can be connected directly to terminal 1 of the ignition coil. A separate adapter is available for determining the throttle valve or carburetor slide position, or you can use a 10kOhm potentiometer and attach it to the throttle valve shaft of your carburetor via the three additional cables (red = +5V, black = GND, and blue = signal).
