5.2 Codificació de la ECU
ECU Coding allows for modification of pre-programmed options within the vehicle's software. This includes:
- Codificació en línia: Connects to OEM servers for data when code data is lost (compatible with VW/Audi/Skoda/Ford/Lincoln/Mazda).
- Variant/Offline Coding: Adapts ECUs for different vehicle configurations (e.g., left-hand/right-hand drive, activating/deactivating software functions).
- Coincidència de components: Establishes communication between new ECU modules and existing systems after replacement.
- Funcions ocultes de Flash: Activates advanced features or disables certain functions (e.g., mirror automatic folding, disabling auto start-stop).
- Customize OE-Settings: Modifies original vehicle behavior (e.g., upgrading fog lamps, battery capacity changes).
- PMI Function: Allows copying data from an original module to a new unit for module replacement (for Ford/Lincoln/Mazda).
