This led to a divide between the "official" software (which was constantly updated by the manufacturers) and the software that could actually run on these cheaper interfaces.

However, many technicians reject DiagBox for older cars because it can misinterpret sensor data, fail to access specific ECUs, or introduce communication errors.
