Description

The Spelab SOTF Switch is a performance tuner engineered for 2001-2004 LB7 Duramax engines, specifically designed to integrate with EFI Live's DSP5 tuning system. This in-cabin switch enables drivers to seamlessly toggle between up to five distinct custom-tuned programs on the fly, eliminating the need for OBD2 reflashing. Its construction prioritizes durability and user experience, featuring a knurled aluminum knob for enhanced grip and heat-resistant wiring protected by split loom for longevity under demanding conditions. The switch is intended for convenient mounting within the cabin, such as on the dashboard, switch panel, or center console, providing quick access to tune adjustments while driving. It is crucial to note that this switch requires your vehicle to be preloaded with a compatible EFI Live DSP5 tune that supports multiple maps. This SOTF switch is explicitly designed for the 2001-2004 Chevrolet Silverado and GMC Sierra 2500HD/3500HD models equipped with the 6.6L LB7 Duramax engine. It is not compatible with 2005 and later Duramax engines. The product is intended for off-road use only.
