The S40 Pro is an economic ECU designed by DTA for relatively simple wasted spark four cylinder engines using semi-sequential injection. 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.
Essential features are not sacrificed to this aim and still maintained are important auxiliary functions to allow this unit to be used on road vehicles where required.
