HITACHI EWR20 - RENAULT (93C66 EEPROM 8/16 BITS)

VIRGIN PROCEDURE FOR RENAULT VEHICLES BASED ON RENAULT ARCHITECTURE ONLY.

IT IS COMMON FOR DATA CORRUPTION TO OCCUR IN THE EEPROM OF THESE ECUS. MAKE SURE YOUR FILE IS NOT CORRUPTED, AS IF THE FILE IS PROCESSED AND IT IS CORRUPTED, IT WILL NOT WORK CORRECTLY AND NO REFUND WILL BE ISSUED.
IF YOUR EEPROM IS CORRUPTED, OBTAIN A NON-CORRUPTED EEPROM IN ORDER TO APPLY THE VIRGINIZATION PROCEDURE.

IT IS NECESSARY TO UPLOAD YOUR OWN FILE FROM THE 93C66 EEPROM READED IN 8 OR 16 BITS (1KB) OF YOUR ECU.

AFTER VIRGINIZING, IN VEHICULES WITH UCH THE ECU IS READY TO BE AUTOMATICALLY CODED WHEN THE IGNITION IS TURNED ON FOR THE FIRST TIME (THE KEY MUST BE RECOGNIZED), IN VEHICLES WITH BCM YOU WILL NEED A TOOL CAPABLE OF CODING THE ECU IN THE VEHICLE.
