ACDelco Gold Remanufactured Mass Airflow Sensors

ACDelco Gold remanufactured mass airflow sensors are high-quality replacements for many vehicles on the road today. A key part of the engine management system, MAF sensors measure the amount of air entering the engine so that the engine control module can determine the amount of fuel to inject. This ensures the most efficient air/fuel mixture for the best fuel economy and power, while reducing harmful exhaust emissions. Remanufacturing the mass air flow sensor is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and are end-of-line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. Order the sensor recommended for your vehicle.

MSD Power Grid Oxygen Sensor Module Harnesses

MSD offers replacement wiring harnesses for the Power Grid Dual NTK wideband oxygen module—a dual channel air/fuel ratio (AFR) system designed to interface with the Power Grid (P/N 7730) to monitor and record the AFR of internal combustion engines. The oxygen sensor module is capable of measuring AFR as low as ? = 0.5 (7.35:1 gasoline AFR equivalent). The AFR range is configurable using the MSDView software in conjunction with the Power Grid Controller (P/N 7730). Excellent MSD range of the NTK sensor gives each unit the ability to accurately monitor AFR's even on alcohol cars. The MSD wideband oxygen sensor module also provides a 0.5-4.5 VDC analog output proportional to the AFR. This analog output can be sent to a gauge or a data acquisition system. A dual-color LED provides the system status at a glance. (To provide accurate backpressure compensated AFR readings on turbocharged applications, the addition of an Exhaust Pressure Module, part number 7767, is required.) MSD can provide a replacement main harness, sensor 1 harness, or sensor 2 harness for your application. Order the model needed to restore proper performance to your vehicle.

RaceChip RX Range Extenders

RaceChip RX range extenders allow you to experience ultimate driving pleasure and unlock additional range for your electric vehicle. These innovative products make it easier to handle your electric vehicle in everyday life with improved responsiveness, up to 10 percent more range, three individual driving modes, and easy installation. RaceChip RX is a plug and play "brainbox" that attaches between the accelerator pedal sensor and the engine control unit to optimize characteristic curves according to the driving mode selected. RX is controlled through the RaceChip app via your smartphone's Bluetooth or through the optional controller. Signals emitted by the accelerator pedal sensor are adjusted via specially tuned characteristic curves, resulting in a more linear torque demand on the electric motor and increased energy recovery when the accelerator pedal is released. As a result, less energy is lost, and energy recovery is improved during braking; the same battery capacity will cover a longer distance. After mounting and connecting the "brainbox", set up the RaceChip+ app to control the RX, and you're ready to go. RaceChip RX with app control is available with or without RX controller. Select the range extender designed for your EV. RX range extender components: * Brainbox--compact low-height design makes it easy to store and fix in the footwell of your vehicle without impacting driver's legroom. It can be mounted in other locations, such as in existing bays or slots, as well as on smooth surfaces in the vehicle * App control-- lets you choose between the three individual driving modes and adapt the RX to your personal driving style with the touch of a finger using your smartphone * Three driving modes: -- Sport-- Improves responsiveness and enhances driving pleasure. Experience sportier driving behavior and better acceleration in sport mode. -- Comfort-- Adjust the pedal response to your personal driving style and enjoy a higher level of driving comfort. -- Eco- Improve your CO2 footprint. More range and fewer charging stops save money and the environment by saving power and money. * Optional controller--wireless and equipped with a high-quality 1.7 in. LCD touch display allows seamless control of the RaceChip RX directly from the dash. It can be mounted anywhere inside the vehicle's interior, depending on your operating habits or preferences. Compact, elegant design blends perfectly with your vehicle's aesthetics.
