Installation of the ECS

  • The location of the ECS needs to be a flat clean surface, e.g. Chassis rail.
  • The ECS is connected directly to the battery and vehicle signals (ABS, Tacho…).
  • Battery plus and ground are not interchangeable to make incorrect installation impossible.
  • ECS is connected to each coil cluster separately for better monitoring.
  • No staging just proportional retardation 0%-100%.
  • Parameter configuration via ECS software.


ECS can be fitted to all CFK and KA Retarders.


ECS (+ & --) and retarder ground are connected straight to the vehicle battery.


All coils are connected with the ECS. No stages, but proportional control.
