SCT Performance Programmers, Tuners, Chips, Monitors, Modules and Calibration Products

 

SCT was founded in 2003, born of the passion & expertise of a team that cut their teeth in performance shops, racing, vehicle calibration, performance parts manufacturing, and aftermarket tuning. From then on, SCT has devoted itself to the idea that engine tuning and calibration is a critical part of customization, and that enthusiasts should have the power to unlock the performance potential of their vehicles. As a result of its recent merger under Derive Systems, SCT, Bully Dog, Bully Dog Big Rig, and Derive Efficiency brands have integrated into a world-class operation and a dominant force in the automotive technology space. SCT's Business Development and Sales teams believe that customized performance is a key part of drivers optimizing their rides. The SCT team of engineers work hard every day to make advances in supported vehicles, off the shelf preloaded tuning, custom tuning, and dealer support, enabling SCT tuning solutions to continually surpass customer demands.

SCT unlocks greater vehicle performance through ECU calibration, so your vehicle is better equipped to meet your specific needs. We've released performance calibrations for hundreds of vehicle makes and models from Ford, GM and Dodge. SCT calibrations are quickly and easily uploaded to the vehicle's engine control module using their handheld programmer technology. By optimizing vehicle calibrations, SCT tuning unlocks greater vehicle horsepower, torque and drivability. SCT aims to provide top-shelf performance when and where it's needed most, and to continue as the benchmark for aftermarket tuning solutions.

SCT's Advantage III custom tuning software is boosting vehicle performance in 26 countries and is available through more than 1,100 dealers around the globe.

Air Intake and Induction » Mass Air Flow Sensors

What is a Mass Air Flow Sensor or MAF?

The mass air flow (MAF) sensor is part of your vehicle's electronic fuel injection system. The MAF sensor calculates the total amount of air entering the engine through the intake tract, and tells the computer how much fuel to inject for air coming through the intake. 

 

 

How does a mass air flow sensor work?

The mass air flow (MAF) sensor has two sensing wires in the housing that protrudes into the intake tube prior to the throttle body.  One wire is heated by electrical current, the other is not heated at all.  As air flows across the heated wire, it cools the wire down. When the temperature difference between the two sensing wires changes, the MAF sensor automatically increases or decreases the current to the heated wire to compensate, telling the computer how much fuel to send through the fuel injectors.

 

How much horsepower and mpg increase can I expect from an aftermarket mass air flow sensor?

Aftermarket performance mass air flow (MAF) sensors replace your OEM sensor and improve on mileage and can increase horsepower by up to 20-HP, depending on the vehicle and engine. Performance MAF sensors increase airflow and low-end torque, without robbing top-end power, and works with factory electronics.

 

What are the symptoms of a bad mass air flow (MAF) sensor?

  • The engine hesitates or drags while under load or idling.
  • During acceleration, you experience hesitation and jerking.
  • The engine coughs, sputters, or hiccups.
  • Excessively rich idling or lean idling.
  • The engine is difficult to start or crank over.
  • The engine stalls or dies shortly after starting.

 

Can you drive with a bad mass air flow sensor?

Yes and no. Yes, you can drive your vehicle with a bad mass air flow (MAF) sensor, but only to get it home or to a repair shop to fix or replace it. Ignoring this problem can lead to far more severe engine problems and damage.

 

Why would a car run better with the mass air flow sensor unplugged?

If your vehicle runs better with your MAF sensor unplugged, you likely have a shorted-out sensor. When the computer does not read a signal from your mass air flow sensor, it provides the computer with a stock signal that will allow you to drive your vehicle for a short period of time to get it fixed or replaced.
