 AEM'S X-Series Wideband UEGO AFR Gauge and Controller

The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16th-inch (52mm) in diameter, and features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEM Wideband Gauges center display. This creates the perception of a larger overall gauge, but in a common 52mm size for easy mounting. Its slim depth (less than one inch overall) and ultra slim cup depth of .200-inches dramatically increases its application base and potential mounting locations.  The X-Series Wideband UEGO AFR Gauge has a user configurable display via buttons on gauge face that allow you to change AFR values for different fuels, Lambda or O2%, change the center display to three or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black dual-faced faceplate for air/fuel and Lambda are included, and an optional silver faceplate with white dual-faced air/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauges robustness.  the gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging. AEMnet allows additional X-Series Wideband Controllers to be daisy chained together (up to 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane and CNG

    Kompact Plumb Back Valve (Diverter Valce) Suit Suzuki Swift, Vitara, SX4 S-Cross (1.4L K14C Boosterjet)

    (0 reviews) Share it View Details

    Turbosmart’s Kompact valve kit has been developed as a direct plug-and-play solution for the Suzuki Swift Sport, Vitara S, Vitara Sport and SX4 S-Cross. 
    The Kompact holds a boost better than the factory valves and can never be overcome by a boost. The result is a more efficient performance from the factory turbochargers and the crisp sound of a piston-style BOV. For those who want blow-off valve sound, the Dual Port both vents-to-atmosphere and recirculates air (TS-0203-1071 DP version), while the Plumb Back is 100% recirculating for quiet, OEM-style operation.
