This is a very basic prototype to bypass the factory installed O2 Sensor in a motorcycle/car and send custom sensor data to the ECU. The purpose of the prototype was to force the ECU to operate on a ...

An O2 or lambda simulator is used to send a simulated oxygen/lambda sensor signal to an engine ECU running in closed loop mode. O2 sensors generate voltages between 0.9V (rich) and 0.1V (lean). A ...
