Data for the gearbox HOW IT CONNECTS Your car. BiMatrix. A new character with 8HP. The car supplies the signals. BiMatrix translates them into the gearbox's language. 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.
