v1.3

v1.3

🚗 Firmware

Changed

• Revised boot message on CAN2
• Optimized serial parsing and CAN transmission
• Optimized fuel level handling
• Optimized DNA drive mode mapping
• Serial protocol updated to prevent corruption caused by special characters

Added

• Shift-light variable thresholds moved to Config.h for easier configuration
