Lambda (λ)

Air/Fuel

air-fuel ratio relative to stoichiometric — Lambda is the ratio of actual air-fuel mixture to the stoichiometric ideal (14.7:1 for petrol). λ=1.0 means stoichiometric. λ<1 = rich (more fuel), λ>1 = lean (more air). DaVinci Deluxe lets you adjust lambda target maps for both economy and power tuning.
