A flex-fuel system adds a sensor and controller that let the factory ECU safely recognize and adapt to ethanol-blended fuel (like E85) instead of just gasoline, without needing a full standalone tune.
why this one — AFD builds this specifically for the 6.2L (2020+ T1XX), explicitly plug-and-play with "no tuning required," confirmed for both GMC Sierra and Chevrolet Silverado in the product title itself.
Running E85 can affect powertrain warranty and requires E85-compatible fuel-system components downstream; check before relying on this for daily E85 use.
