Maintaining the highest manufacturing quality and reliability of more sophisticated ECU’s in the S series range it provides a lower priced solution for a wide range of applications.
The primary aim of the S40 is to provide an economic ECU for relatively simple wasted spark four cylinder engines using semi-sequential injection.
Advanced features and system flexibility, however, are in no way sacrificed to this aim.
