Benefits of the AFD Plug and Play E85 Flex Fuel System for 2018-23 Mustang GT and Mach 1
Enhanced Performance and Power
The AFD Plug and Play E85 Flex Fuel System for your 2018-2023 Ford Mustang GT or Mach 1 allows you to utilize E85 fuel, a blend of gasoline and ethanol, to significantly enhance your vehicle’s performance. The higher octane rating of E85, typically around 100-105, compared to standard gasoline, enables the engine to run more efficiently and produce more power. The system optimizes the engine’s performance by adjusting the fuel delivery automatically. This leads to more aggressive ignition timing and increased compression, which, in turn, results in substantial gains in both horsepower (HP) and torque. For example, users have reported gains of up to 20-30 wheel horsepower (WHP) with the AFD system.
- Increased Horsepower
- Improved Torque
Cost-Effectiveness and Fuel Efficiency
In many regions, E85 is available at a lower price per gallon than premium gasoline, which can translate to significant savings at the pump. While E85 generally results in slightly lower fuel economy compared to gasoline, the lower fuel price often offsets this difference, leading to a lower overall cost per mile. The efficiency of E85 can vary depending on driving conditions and the specific vehicle setup, but the cost benefits often make it an attractive alternative for performance enthusiasts. For example, if gasoline costs $4.00 per gallon and E85 costs $3.00, even with a 10-15% reduction in miles per gallon, the overall cost per mile can still be lower when using E85.
- Cost per gallon E85, compared with Gasoline
- Fuel efficiency on E85 compared to gasoline
Optimized Engine Performance
The AFD Plug and Play E85 Flex Fuel System optimizes engine performance by automatically adjusting the fuel blend based on the ethanol content detected by the included ethanol sensor. This ensures that the engine receives the correct fuel mixture at all times, maximizing power output and efficiency. The higher octane rating of E85, typically 100-105, compared to the octane of gasoline (87-93), allows for more aggressive engine tuning, resulting in increased horsepower and torque. This system allows for a seamless transition between gasoline and E85, providing the flexibility to use either fuel without any manual adjustments. It supports the vehicle’s engine control unit (ECU), which further enhances the engine’s performance and longevity.
- Better engine performance by adjusting the fuel blend automatically.
- Benefits of higher Octane
