The new ECU Module is designed to be easy to install and uninstall and will provide your new smart with a noticeable power increase.

How much power can be gained from this upgrade?

Horsepower has been raised by approximately 15% from 160hp to 186hp!

This new generation of ECU Modules features a Multi Map Technology that ensures maximum performance with minimum load. The new Multi Map ECU Tuning Module comes with variable mapping that allows you to custom tune the module depending on your desired driving needs. You can simply leave it where it is when it is delivered to you out of the box or modify the parameters as you wish. The microprocessors that are being used are significantly different then any other plug in unit. are of particular importance. The unit is designed to output calculation cycles that correspond exactly to those of the main ECU. The end result is smooth, reliable power gains with an option for customizing the power delivery to your specific liking/ needs (settings available are within the safe operating zone of the engine to prevent you from doing damage). This type of a design allows for real time scanning to make sure that the main ECU protection functions are not affected.

Self Learning Auto Calibration

This module also features a built in ability to learn the unique driving characteristic of the FIAT 500X. During a short run-in period, the memory function gathers the individual data on the different injection cycles. The information obtained serves as a basis for optimization. This way, standard tolerances are compensated for and the best results obtained for FIAT 500X without any complicated manual settings.

Another advantage of this Multi Map Technology ECU Module is the fact that it adheres to the legal emissions standards for the vehicle. Due to the optimized combustion across all performance ranges the fuel is used 100% efficiently - smoke and soot are history. This module is also TÜV Certified for our European Drivers.
