MAF

If you’re researching electronic fuel injection (EFI) systems, you’ve probably come across the terms speed density and mass air flow (MAF). These are the two most prevalent types of fuel injection metering methods that an EFI system uses to calculate air/fuel ratio. (Some vehicles even use a combination of the two.) Though there is other

Your mass air flow sensor, or MAF, is a critical part of your engine. It tells your engine control unit (ECU), or simply “computer” how much air is entering the engine. The ECU uses that data to adjust the amount of fuel to deliver to ensure an optimal air/fuel ratio. Unfortunately, since they’re precision electronic
