Throttle flap controller Map/Maf is designed for controlling throttle flap, which determines richness of mixture for petrol engines. Thanks to better petrol combustion, less amount of fuel is needed, so it is necessary to decrease injected dose of fuel and reach desired fuel saving.

Controller must be connected to the signal wire from throttle flap and you can easy set richness of mixture by potentiometer on controller.

Poor mixture - weak performance of engine

Rich mixture - higher rpm in engine idling

You need to set potentiometers exactly to correct values. With switch CITY / HWY you can select city or highway operation. (stored values will save and you just select between them)
