{"product_id":"3-bar-map-sensor-28","title":"3-Bar MAP Sensor","description":"The AMP EFI GM 3-Bar MAP Sensor is engineered for high-performance, boosted engine applications, enabling precise monitoring of boost pressures up to 29 psi. This sensor is a crucial component for turbocharged or supercharged vehicles seeking accurate air-fuel ratio management, and it is frequently paired with MegaSquirt and other aftermarket ECUs.\n\nConstructed with a durable, 3-pin weatherproof connector, the sensor operates on a standard 5V input and provides a linear output voltage (0.1V to 4.9V) corresponding to its pressure readings. Its calibration is linear, with a 0V output representing 1.1 kPa and a 5V output representing 315.5 kPa. This allows for precise data interpretation by your engine control unit.\n\nInstallation involves connecting Pin A to Sensor Ground, Pin B to the ECU's Output Signal, and Pin C to the ECU's 5V Vref. For tuning, the sensor calibration can be managed within TunerStudio under Tools \u0026gt; Calibrate MAP\/Baro, with common MAP sensor types including the GM 3-Bar \/ MPXH6300. Once configured, the calibration is burned to the MegaSquirt ECU.\n\nThis sensor fits most GM vehicles that are factory-equipped with a 3-Bar MAP sensor. Options are available for the sensor only, or with a 6\" pigtail or a connector and pins for a more complete installation solution.","brand":"AMP EFI","offers":[{"title":"Default Title","offer_id":52871908131128,"sku":"GM3BarMap-wConn","price":77.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-bar-map-sensor-28","provider":"MOTORMIA","version":"1.0","type":"link"}
