By carefully analysing your tractor Opel Opel Astra 140 hp we are able to fine tune your motormanagement programme, or ECU (Engine Control Unit), to enable optimal fuel efficiency. This software largely determines how the engine of a Opel [mode] 140 hp tractor behaves as well as determining fuel use. ECO Setting is a software product that is designed to fit with all Opel Opel Astra 140 hp tractors and is tailored to actual use. The result is improved performance, smoother acceleration, optimal fuel efficiency, more torque at lower RMP and better throttle response. Optimising the torque curves in the Opel Opel Astra 140 hp allows for more torque at lower RPM, allowing you to change gears earlier, resulting in fewer RPM and improved efficiency in the Opel Opel Astra 140 hp.
