Mazda RX-8 Cosmo Edition — Reliability Calibration

Mazda RX-8 Cosmo Edition upgraded with a reliability-focused ECU calibration by DMS Tuned. The goal was to enhance cooling efficiency, lubrication and overall engine safety while preserving the character of the legendary rotary engine.

Upgrades Applied

  • Lower cooling fan activation threshold for improved thermal control
  • Additional oil injection for enhanced rotor lubrication
  • Refined throttle response mapping
  • Slightly richer AFR under load for increased engine safety

Calibration Philosophy

Rotary engines require careful thermal and lubrication management. This calibration focuses on reducing heat stress, improving oiling strategy and maintaining stable air-fuel ratios to extend engine longevity. The result is improved drivability and enhanced reliability without compromising performance.
