The Mono-Motronic is an electronically controlled, multipoint injection system. The original schematic of this system claims that it is similar to the Mono Jetronic except it has added ignition control functions. I fail to see where the similarities are. This system is a multi point, uses two lambda sensors, has EGR and uses a MAP sensor. Since there is no distributor, The ECU controls the ignition function via crank or cam angle sensors.
