What AFR should I run? Choosing the right lambda for the conditions
Lambda targets aren't a single number copied across the map. Why each zone wants something different, where to start, and the constraints that set the limits.
Why bore diameter determines knock frequency
Knock frequency is set by bore diameter. The formula, the resonant modes, why Mode 0 is the default and Mode 2 is the strongest fallback, and how to use the calculated value in practice.
How ECUs calculate fuel delivery
The VE table isn't always storing what you think it is. Where airflow estimation ends, where the fuel model begins, and why errors in one end up in the other.
Why knock appears under some conditions and not others
Knock threshold isn't a fixed number. It moves with ignition timing, boost, intake air temperature, coolant temperature, fuel octane, AFR, and engine speed simultaneously.
How ignition timing produces torque and what limits spark advance
The physics behind ignition timing decisions, what MBT means in terms of cylinder pressure, and where knock sets the ceiling.
What your VE table shape tells you about your engine
VE tables aren't just fuelling maps. The shape tells you how the engine breathes, where it's most efficient, and where something might be limiting performance.
