The Future of Performance Fuel: Why Outdated E85 Methods Must Be Replaced

E85 is a high-octane powerhouse, offering significant performance gains for enthusiasts. Yet, for too long, this fuel's potential has been shackled by inadequate and primitive engine management and tuning methods. These widely-used, unfortunately incompetent systems introduce unnecessary risk and inconsistency, preventing E85 from being a truly reliable performance choice.

Advanced Fuel Dynamics understands that to fully leverage E85, the technology controlling it must be state-of-the-art. That is why our team invests countless hours in R&D, developing the industry's best sensors and products to eliminate risks and ensure E85 can be properly utilized as a predictable, high-performance fuel.

The Problem: How Outdated Methods Undermine E85 Performance

Current, widely-used methods for running E85 are often based on guesswork, reactive tuning, and low-fidelity hardware. This approach is fundamentally flawed because E85 is not a static fuel, leading to significant compromises in safety and power.

  • Inconsistent Fuel Blends are Ignored: E85's actual ethanol content fluctuates constantly based on the station, season, and temperature (often ranging from E51 to E83). Traditional "fixed tunes" are set for one blend, making them:
    • Too Lean: Risking engine damage when the fuel is leaner than expected.
    • Too Rich: Leaving horsepower on the table when the fuel is richer than expected.
  • Primitive Sensor Technology: Many existing ethanol sensors such as Continental and GM are slow to react and lack the resolution needed for precise, real-time tuning. This delayed and low-quality data forces the engine's computer to constantly play catch-up, introducing risk during rapid changes.
  • Reliance on Guesswork and Compensation Tables: Outdated systems rely on pre-set estimations rather than measuring the exact ethanol content and compensating instantly. This margin for error is unacceptable for high-performance engines.

The Solution: Advanced Fuel Dynamics' Focus on R&D

Our commitment to R&D is centered on replacing speculation with precision, ensuring E85 is managed flawlessly to unlock its full, safe potential.

  • Development of High-Resolution Sensors: We invest in creating superior sensors that deliver instantaneous, highly granular data on the exact ethanol percentage. This allows for micro-adjustments in fuel and timing, ensuring the engine is always running optimally.
  • Proactive Engine Management: Our systems utilize advanced control strategies to move beyond reactive tuning. By reading the precise blend in real-time, the system proactively adjusts the tune before any inconsistency can impact engine performance or safety.
  • Eliminating All E85 Associated Risks: Through comprehensive R&D, our products are engineered to provide reliable, dynamic fuel management. This eliminates the unpredictability of fluctuating fuel blends, making E85 a consistent and safe high-performance choice for any vehicle.
