Engine control type All essential signals arrive over CAN. Signals arrive through BiMatrix inputs. Maps supply the torque data. No ECU needed: sensors supply the signals, and an external pulse source supplies RPM. No target / actual torque Torque from Maps X/Y Missing torque data? BiMatrix calculates it using maps. Even if the ECU does not transmit all torque data. Maps X/Y can estimate target and actual torque from engine speed and load. This calculated estimate must be tuned to the engine. Minimum signals required to run the gearbox: — engine speed — accelerator pedal position — brake signal CLT — coolant temperature The diagram shows the data flow.
