CSP5 5-Position Tuning Switch

The Fish Tuning CSP5 5-Position EFI Live Tuning Switch provides on-the-fly tune adjustments for 2006-2019 Dodge Ram trucks equipped with 5.9L and 6.7L Cummins engines and an EFI Live tune. This switch bypasses the need to wait for a programmer to reflash the ECM through the OBD2 port, allowing for immediate tune changes by simply turning the switch. The kit includes a detachable switch with a wire and OBDII pass-through connector, a black aluminum knurled knob, and a numbered 1-5 decal for easy identification of tune positions. Installation involves plugging the switch into the OBDII port, which also provides pass-through functionality for other devices. An LED light is included to verify correct installation. It is crucial that the tune in the PCM is configured for CSP maps; if tunes are from another tuner, they must be contacted to set up tunes properly for this switch. The updated switches are compatible with all 2006-2007 5.9L and 2007.5-2019 6.7L Cummins models.
