Unlock race-ready performance and ethanol flexibility in your 2007 Renault Mégane RS 2.0 Turbo 225 hp.
This Stage 2 calibration for the Sagem 3000 ECU combines higher boost & ignition advance with:
• **Vmax delete** — factory top-speed limiter removed
• **Decat** — catalyst efficiency checks & post-cat O₂ DTCs disabled
• **E85 conversion** — adaptive stoichiometry, cold-start enrichment and knock control for blends up to E85
The file was bench-read via Alientech Kess V2 and is fully checksum-corrected — ready to flash with any Sagem 3000-capable tool. For competition/off-road use only; verify local regulations before installation.
