Technical Description

Engine Control System: Bosch Motronic ME 7.1.1

The Bosch Motronic ECU manages and controls the engine functions. The management system is divided in two 4-cylinder units, with an ECU and integrated ignition/injection and fuel pump controls. Air flow meter, throttle angle potentiometer, RPM and timing sensors, and motor-driven throttle body. Linear oxygen sensor and ON/OFF on each exhaust branch, closed loop carburetion, detonation/diagnostics/misfire sensors. CAN serial line for interfacing with other vehicle control systems that interact with the engine management system. The main objective of the engine control system is delivering engine torque ("Torque based" model). This strategy is applicable in all conditions of engine operation. Mototronic essentially identifies three different torque request levels: driver torque request, external torque request, and internal torque request.
