How does the CSP5 let me switch EFI Live tunes on the fly?

Compatibility depends on the tuning installation and harness used, so confirm with your tuner or product documentation before ordering.

What are the physical features and installation basics of the CSP5?

The CSP5 is a compact, dash-mountable rotary or lever-style 5-position switch designed for durability in truck cabins.

Will using this switch affect warranty or diagnostics?

The CSP5 itself is an accessory that selects between preloaded tunes; it does not reflash the ECU by itself. However, any aftermarket tuning may be visible to dealers or affect warranty coverage depending on manufacturer policy and local regulations. Always consult your vehicle warranty terms and your tuner for guidance on recordable changes and diagnostics.

• Switch selects stored EFI Live maps — does not alter ECU firmware
• Aftermarket tunes can be detectable during dealer diagnostics
• Check warranty and emissions regulations before tuning
• Your tuner can advise on reversible or stealth options if needed
