This shows maximum torque is reached at 5000 RPM and 13.33 AFR.
Here’s the same chart as a 3D surface:
One can clearly see the trend to a torque peak (1) at about 13.3 – 13.4 AFR for this particular
engine at that engine’s current timing settings. A secondary peak exists at a different RPM at (2).
The key to good tuning of course is to arrive at the maximum torque achievable without engine
knock by varying both, timing and fueling.
