Will increasing Power and Torque increase fuel consumption? This will typically improve driveability, reduce fuel consumption and may increase available power and torque. flat spots or creases in maps that are there to allow drive cycle emissions to be improved can be calibrated out. optimised over a very specific drive cycle, unfortunately this does not represent real world driving well, when retuning a vehicle this is typically recognised and the tune is optimised for real world driving, typically emissions are not drastically different under real world conditions e.g. By running a tune that takes full advantage of an engines real potential it is most often possible to make significant performance gains The software will also be optimised to meet emissions standards, i.e. In this case development costs for the car manufacturer are also reduced because they are able to capitalize on producing much higher volumes of essentially one engine running a number of different tunes across different models.
The tune that your car was sold with might deliberately detune the engine so it produces less power and torque than identical engines sold as different models, car manufacturers do this so they can charge a premium for vehicles that are higher in the range. These are not all goals that align with what you would like from your vehicle. Why can Power and Torque be gained from tuning my car?ĮCU software is “optimised” to meet various goals that the car manufacturer has.
