52045262 Fiat 500 Plug & Play with Stage 1 Remap Ecu.

Increased brake horse power can be achieved with the plug and play ECU. Once the ECU is fitted, it will automatically code itself to the vehicle. To complete this process, a scan tool is required, which makes it very easy to do. The ECU file has been remapped to stage 1, providing enhanced performance. Please note that no returns are accepted for the ECU as it has been bench tested to ensure its functionality.

Keep your old Ecu and this gives you the option to go back to standard when you want, or for MOT testing
