CSP5 Switch Pass Through Switch.
(The pass through OBDII connector allows other devices to be used simultaneously with the CSP5 switch).
CSP5, EFILive's custom operating system for the Cummins CM2200 and CM2350B ECM's allows customers to switch 'on the fly' between a number of different tunes, all stored in the ECM's flash memory. By having multiple tunes instantly accessible, customers no longer need to re-flash their ECM to change their tunes to suit changing conditions (e.g. racing, towing or power limiting). Simply build up your tunes, flash the ECM once and then select your desired tune using the SoCal Diesel CSP5 switch.
