KTM 950 Adventure Typical ECU and Ignition System Wiring DiagramThe KTM 950 Adventure usually consists of ECU (control unit), , ignition lock, emergency off switch, pulse generator, ignition coils, fuel pump , throttle potentiometer (TPS), and octane selector. voltage from the (1) flows to the ECU (control unit) through the switch on ignition lock (2) and the switched on emergency OFF switch (3). The pulse generator (5) reports the crankshaft position to the ECU (4). The ECU uses this signal to calculate the ignition point for each cylinder. voltage is supplied to both ignition coils (6) via the emergency OFF switch, the ground is switched by the ECU. (click image to enlarged).

The coil on the fuel pump (7) obtains voltage from the ECU. After ignition is switched on, the fuel pump switches on for a few seconds and switches off again. If you start with the engine running, the fuel pump will stay on. The fuel pump obtains voltage from the through the switched on ignition lock, via the fuse and the contact on the fuel pump . The throttle potentiometer (TPS) reports the position of the carburetor throttle valves to the ECU via the yellow cable (on connector AM or AR). The TPS is supplied with 5 volts of supply voltage (blue cable on connector AM or AR) by the ECU. The black cable supplies the ground.

The ECU receives a ground signal via the connected octane selector (10) which is connector BA and BF, and uses the stored ignition curve for fuel with a minimum octane number of 95 (ROZ 95). If the octane selector is disconnected the engine can be operated with fuel with a minimum quality of ROZ 80
