Lambda and Fueling: A Safer Interpretation
A bounded guide to lambda-related log context for VAG performance and health conversations.
Keep units explicit
Lambda, AFR, requested mixture, and measured mixture are not interchangeable labels. Preserve the source units and fuel context.
Do not diagnose from one channel
Fuel pressure, trims, load, temperature, and sensor health can change interpretation. Use a qualified technician for consequential decisions.
