MTM Engine Modifications
What is Chiptuning?
More power output, more torque, less fuel consumption – all this and much more – with chip tuning.
Electronics in automotive engineering
Since the 80’s electronics have played an increasing role in automotive engineering. Initially simple functions were monitored and the electronics only rarely took on an active function in the control of the vehicles operations. Nowadays almost every function in a car is controlled or electronically monitored by software or electronically. One of the central functions influenced by electronics is the vehicle’s engine management.
The increasing demand for more power output, less fuel consumption, lower emission and better driveability on modern engines has brought along an increased complexity of the hardware and software requirements in engine management. The engine control unit ECU is the central part in engine management, from different input values from a variety of sensors it determines appropriate values suitable for the engine’s current operating status. Engine rotation speed, air mass, intake air- / fuel temperature and of course also the accelerator position are inputted in the calculation. Depending on the engine type (Petrol or Diesel), when chip tuning an engine the relevant operating factors like fuel injection amounts, pressure boost, ignition- and injection time are changed for the specific engine type.
More power output and torque
Most engines are mechanically constructed by the manufacturer to suit a wide power spectrum consequently with controlled alterations of the ECU software, more power output and torque can be realized from the engine without damaging the stability of components or imperilling the suitability of the vehicle for daily use.
Developing a power upgrade
When pre selecting an engine type for modification, to start with the separate criteria of the vehicle are examined. Since, in detail, every vehicle presents slight differences, the particular vehicle data is recorded with every development project. Afterwards a detailed new synchronization of the characteristics and data is completed on the mtm rolling roads. The serial safety mechanisms like the maximum allowed pressure boost, protection of overheating protection, knock control system etc of the engine management system are unchanged subsequently the vehicle handling is tested on the road and when necessary a further fine tuning of the data is carried out. When all the desired standards in power output, torque emission levels are achieved the upgrade get its technical approval and is introduced to the mtm sales programme. For all upgraded vehicles we strongly recommend using SuperPlus 98 octane fuel.
