BTWTuning EcuTek Calibration – BMW M340i & Toyota Supra (B58TU) 

Built for enthusiasts who demand more than generic flashes, BTWTuning’s EcuTek calibration for the B58TU engine takes performance tuning to a data-driven level. Every map is developed using in-house dyno validation, extensive road testing, and log analysis to ensure maximum performance with OEM-level reliability.

Technical Highlights:

  • Peak Power & Torque Gains – Calibrated to safely maximize load, timing, and boost control for significant performance improvements.

  • Refined Throttle Mapping – Eliminates stock dead zones and lag for linear, predictable pedal response.

  • Map Switching & Flexibility – Multiple drive modes allow you to toggle between pump gas, ethanol blends, or track-focused calibrations at the push of a button.

  • Fuel System Optimization – Fine-tuned fueling strategies balance power with efficiency, ensuring consistent AFR stability under varying conditions.

  • Logging & Data Integration – Full EcuTek ProECU support allows you to monitor, log, and refine performance metrics with precision.

  • Reliability First – Knock control, torque management, and safety protocols remain intact to protect your engine while unlocking its true potential.
