Engine chip tuning for Mercedes-Benz S 500 SEC 85-91 252hp

MyChiptuningfiles specialise in optimising petrol and diesel engines for improved performance and fuel efficiency. We have years of experience tuning Mercedes-Benz engines to optimise for performance and efficiency.

The process

We analyse your vehicle and can adjust the engine management programme, also known as the ECU (Engine Control Unit). This engine software is largely responsible for the behaviour of the Mercedes-Benz S 500 SEC 85-91 252hp engine and its fuel consumption. We can optimise the ECU for any car, van, truck or tractor.

The benefits

In the case of the Mercedes-Benz S 500 SEC 85-91 252hp engine, our chip tuning file is tailored for more power and torque, reduced fuel consumption, smoother acceleration and improved throttle response. By optimising the torque curve the Mercedes-Benz S 500 SEC 85-91 252hp engine produces more torque at lower RPM. This also means that you can change gear earlier, so your Mercedes-Benz engine will run at lower revs and therefore more efficiently.

Many engine chip tuning companies all over the world choose MyChiptuningfiles for their Mercedes-Benz chip tuning files. Our Mercedes-Benz S 500 SEC 85-91 252hp engine chip tuning file provides the best possible performance and results within the original safety margins.

  • "My Chip Tuning Files/Fuel Saving Technology is the absolute best in modifying within the safe parameters of your vehicle's stock components! I searched around and tried others with mediocre results. If I have questions about anything I have a direct contact to deal with, not some bulk messaging where you do not know who is talking to you. The personalized service has earned them my business for now and the future. My customers here in Atlanta, Georgia USA and my customers throughout the world are happy and they would not be without the service I receive here. HIGHLY RECOMMEND!" Atlanta, GA USA

  • Wij zijn zeer tevreden met de resultaten van ''MyChipTuningFiles'' Niet alleen wij maar ook al onze klanten rijden weg met een glimlach op hun gezicht! Er zijn veel chiptuning bedrijven die een standaard software gebruiken, maar bij ''MyChipTuningFiles'' hebben we gezien dat de originele software speciaal op maat word herschreven voor elke merk/type auto! Kortom dus professioneel! Dankje MyChiptuningfiles!
