The primary aim of the S40 is to provide an economic ECU for relatively simple wasted spark four cylinder engines using semi-sequential injection.

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.

S80 PRO

The S80 and S100 ECUs represent the top of the range, differing only in the number of individual coils and sequential injectors they can handle.

Comprehensive input and output features are provided allowing sophisticated 6, 8 , 10 and 12 cylinder engines to be controlled easily and successfully.

An extremely high level of environmental protection has been implemented in its design allowing safe use in extreme conditions such as grass track, off road, marine and motorcycles.
