CS Electronic’s new Competition CSX stock spec speed controller is a highly updated version of their 2009 World Championship winning CS Rocket speedo. Especially designed for stock racing classes the new controller offers special power programs and a 9.5T motor limit. Smaller dimensions and lower weight as well as a modular design make for an easier installation in the car. Depending on weather conditions, or the motor used, the heat sink or fan can be added to the CSX to lower operating temperatures. The three power capacitors now reside on a separate board for easier installation and exchange. New solder tabs for the power wires makes changing them a breeze. Software-wise the speedo offers 6 modified programs, 4 ‘outlaw’ stock power programs and 4 ‘legal’ stock programs. Usable with both sensor and sensorless motors CS Electronic’s new controller also offers a PC interface for easy update and storage ability.
