Release notes

Release Notes — v1.0

This first public build delivers a full Stage 2 calibration for the S55-powered BMW M3 Competition.
The file eliminates all torque and boost limitations, introduces an aggressive Pop&Bang exhaust over-run in Sport and Sport +, and sharpens throttle response while preserving OEM-smooth driveability in Comfort mode. Lambda targets and ignition timing have been revised for high-octane fuel, with validation up to E30 ethanol blends. Complete checksum correction and a CVN раtсh ensure seamless flashing via CMD Flash Slave without triggering dealer overwrite.

Motorsport/off-road use only. Ensure compliance with local emissions rules before installation.
