Does the device work on cars with an engine management system and a Lambda?
(A) Yes see above. A Lambda is an electronic oxygen sensor in the exhaust system which tells the ECU (Electronic Control Unit) about the AFR (Air Fuel Ratio). Most modern systems recalibrate if the combustion process improves but if not, when the car is cruising (throttle pressure is neutral) the system is said to be closed loop and the AFR is set as close to the Stoichometric rate as possible, automatically correcting any leaning in the AFR created by the CB-26P but still allowing the benefits of the Swirl. When the engine is accelerating or decelerating the system is open loop allowing the CB-26P to work to maximum effect. On modern EFI (electronic fuel injection) cars the engines are set up to work pretty efficiently and the main benefits of the CB-26P will be improved acceleration and throttle response.
