Physical engine model for fast application

• determine engine load by throttle position or air pressure signals
• mixture control and basic ignition guided by main signal relative load rl
• Subsystems pit speed-, launch-, rpm-limiter and ASR are integrated inside torque control
• Separated power cut functions to assist several gear cut systems
• Diagnostics
• Integrated safety strategy for 2 electronic throttle controls
