Choose one fuel family
-
Gasoline only: three gasoline maps, such as 91, 100 and 110 octane, matched to your vehicle and fuel requirements.
-
E85 only: three enhanced maps using E85 as the base fuel, with different power levels and, on boosted builds, different boost levels.
Gasoline and E85 cannot be combined in the same three-map package. This package does not provide flex-fuel operation.
Configured for your build
FastUTV develops the tuning for your vehicle. Confirm the year, model, modifications and chosen fuel family with FastUTV before calibration. Supporting hardware and final map settings depend on the vehicle and fuel system.
Supporting hardware, accessories, installation and dyno time are separate from the ECU-and-three-map price. No specific horsepower or boost figure is promised.
