JMS is revolutionizing Ford mass air fuel injection systems with the Mass Air Modifier for Ford and GM vehicles. This simple and easy to use in-line MAF tuning device is designed to accurately scale and filter the mass air signal on all MAF equipped Ford cars, trucks and SUV's.

Factory and aftermarket mass air meters have long been a source of frustration for tuners. The JMS Mass Air Modifier is the only product that can filter the mass air signal, while also scaling the signal to extend the dynamic range of the sensor. Cold air kits, camshafts, and the architecture of your air inlet on a turbo or supercharging system are just a few examples of what can cause turbulent airflow and a noisy mass air signal.

By filtering the MAF signal you can clean up a "noisy" signal area that may be causing a drivability issue. The JMS Mass Air Modifier features a simple switch that allows you to choose between filtering the signal at idle or cruise. Use the rotary switch to choose between 16 built-in levels of filtering, filter only as much as the signal needs to be cleaned. Tuners will benefit greatly from this innovative concept, now they can quickly change the mass air signal in real-time on the dyno, and see instant results via basic OBD-II data logging. You can also choose to filter the signal based on the MAF frequency, or you can filter based on another input from a 0-5 volt sensor. With seven unique filter ranges you can fine tune the filter to your problem area.

Scaling the mass air meter is essentially extending the dynamic range of the sensor by modifying the curve of the signal to eliminate "pegging" or a saturated mass air flow signal, as result of larger air flow. Tuners can use this feature to raise or lower the curve for improved performance, or fine-tune the signal for various size fuel injectors and mass air inlets. Another added benefit is the ability to correct lean or rich fuel codes caused by basic aftermarket upgrades such as a cold air kit, and you can correct the issue without a laptop or OBD-II programmer while maintaining a warranty-friendly status at the local dealership. To help support advanced tuning features, JMS offers a simple spreadsheet that provides mass air flow values for use with aftermarket custom tuning software, along with thorough instruction manuals and video how-to guides. They also offer a version of the JMS Mass Air Modifier that's primary purpose is to increase the mass air signal. This unit is typically used by a tuner when a customer is using a MAF sensor for a high horsepower vehicle on a much lower horsepower vehicle.

The JMS Mass Air Modifier features advanced electronics housed in an aluminum case, a complete OEM-grade plug and play wiring harness using shielded cable, with additional cables for 0-5 volt signal input and optional on-board enable/disable switch. Specific wiring harnesses have been designed around the common Ford and GM MAF Sensors. Other vehicles are supported based on the MAF sensor and connector type. The device operating voltage range is 9.5-20 volts DC, and it is compatible with 12 or 16 volt DC power systems. The complete system is designed to be used with any factory or aftermarket mass air meter regardless of size, will support a wide range of fuel injectors, and is offered for both digital and analog mass air sensors.
