How does a performance mass air flow sensor work?

How does a performance mass air flow sensor work?

As you bolt on performance engine mods that increase air flow, your original MAF may not be able to gauge the higher volume of air, making it impossible for your car’s computer to accurately read the sensor’s signals and add the correct amount of fuel to match.

What does a performance MAF do to a car?

When the fire is lit, it produces heart-pounding horsepower. But if you’ve added a bunch of performance mods to your ride’s motor and are still rocking the stock sensors, you may be missing out on a few easy-to-wrangle ponies. Luckily, you can take full-advantage of your mods by installing a performance mass airflow sensor, but what does it do?

How does the performance chip work on an Audi?

The performance chip plugs directly into your OBDII Port and immediately starts analyzing everything within the ECU’s (Electronic Controller Unit) reach, which is a LOT of control. So now, the rest is up to you: Are you wanting to save on gas, or looking to have a blast behind some real power when you press that pedal?

What are the lights on a performance chip?

The lights are an initial visual indicator the performance chip and ECU are in communication and the software is syncing to your engine’s ECU during that initial 150 Miles. There is no need to monitor the lights as they will likely dim after a short period of time.

Can a MAF sensor be substituted for an AFM?

Tech Note Air Flow Meter to MAF Conversion. The replacement of a stock vane-style air flow meter (AFM) with a mass air flow (MAF) sensor is one of the most effective ways to improve performance on a naturally aspirated engine. It is common to produce gains of 10 hp at the wheels on engines in the 2.5L range and higher gains on larger engines.

How are MAF sensors used in fuel injectors?

MAF sensors come from the factory calibrated to measure a certain range of air flow, and to work with particular flow rate fuel injectors. This calibration is flexible enough to allow the addition of performance accessories like a performance air intake system, so you can realize the air flow,…

Which is better Bosch air flow meter or MAF sensor?

The photo below shows a Bosch air flow meter from a BMW E30 M3 on the left compared to the MAF 3.5 sensor on the right that is used to replace it in the Split Second MAF Kit. Note that the air flow meter has lots of sharp edges and protrusions that can impede air flow. The MAF sensor has a smooth opening and much larger cross section.

What’s the difference between TN2 AFM and MAF AFM?

The photos below compare the stock AFM installed on an E30 M3 on the left with the MAF 4.0 sensor installed on the right. In addition to the larger diameter of the MAF sensor you can see the much larger diameter of the elbow connecting the MAF sensor outlet to the plenum.
