Fish Tuning CSP5 5-Position Switch for EFI Live Tuning - Direct

In this review of the Fish Tuning CSP5 5-Position Switch, the bottom line is simple: this is a focused replacement switch for owners using EFI Live tuning on 06-18 5.9L and 6.7L Dodge engines who need reliable position control. The reviewer found it most useful for technicians and experienced DIYers who already use EFI Live or similar systems and want a straightforward, functional switch to restore or add multi-position tuning control. It is not a plug-and-play instrument cluster upgrade for casual owners, but it delivers the core functionality it promises.

Key Features

• 5-Position Control: Provides distinct selectable positions for tuning presets, making it simple to switch between maps while driving or testing.
• EFI Live Compatibility: Works with EFI Live tuning setups commonly used on 06-18 5.9L and 6.7L Dodge trucks, offering integration with established tuning workflows.
• Direct Replacement Fit: Designed to replace a broken or worn switch in existing installations, reducing the time required for repair or restoration.
• Solid Mechanical Action: The switch gives a firm, tactile click for each position so users can feel when a new tuning stage is selected.
• Compact Form Factor: Small footprint allows mounting in tight dash or console locations without major modifications.

Who It's For

This switch suits owners of 06-18 Dodge 5.9L and 6.7L trucks who run EFI Live or compatible tuning systems and need a reliable multi-position selector. It is ideal for tuners, shops, and experienced DIYers who understand wiring and mapping so they can integrate the switch into their existing setup.

It is less suitable for users who want a plug-and-play, out-of-the-box dashboard upgrade without any wiring or configuration, or for those who need an all-in-one tuning solution. Novice users should seek professional installation or a product marketed specifically for easy consumer installation.
