Show original supplier description
The P3 V3 Gauge is a digital OBD2 individual gauge designed for seamless integration into your vehicle's air vent, offering a clean, OEM+ aesthetic. This gauge enhances your driving experience by providing real-time data directly from your ECU, often with greater accuracy than factory readings. Installation is designed to be plug-and-play, connecting directly to your OBD2 port, with an optional hard-wire harness kit available if you wish to keep the OBD2 port free. The V3 model offers increased user control, allowing you to read DTCs on command, remove PIDs you don't wish to see, configure individual measurement units, and calibrate vehicle speed in 1% increments (-9% to +20%). The P3 V3 Gauge is engineered to withstand extreme temperatures, functioning reliably from -94°F to hundreds of degrees Fahrenheit, ensuring durability in harsh in-car environments. It provides a wide array of readouts, including Boost (via OBD2 or optional analog sensor), Coolant Temperature, Air/Fuel Ratio (Lambda), Vehicle Speed, Intake Air Temperature, Throttle Angle, Ignition Timing, Engine RPM, Exhaust Gas Temperature, and Battery Voltage. Additionally, it features a programmable shift light, two 0-5 volt analog inputs for external sensors, and acceleration/braking timers.
