The narrowband sensor your car came with only knows \"rich\" or \"lean\" right around stoich, which is useless the moment you start tuning for power. The AEM X-Series wideband reads your real air\/fuel ratio across the whole range, and this is the OBDII version, which means instead of running its own separate sensor network, it puts your AFR right onto the factory CAN-bus stream your ECU is already sending out the OBDII port.\u003c\/p\u003e\n\n\u003cp\u003eThat's the whole point of this version. If you're tuning on a piggyback module or open-source software, your AFR shows up in the same data stream as everything else the ECU reports, so you're logging and tuning off one clean source. It plays with HPTuners, EFILive, DashDaq, and the rest.\u003c\/p\u003e\n\n\u003ch4\u003eThe Sensor and Calibration\u003c\/h4\u003e\n\n\u003cp\u003eIt comes with AEM's OBDII connector and a Bosch 4.9LSU wideband sensor, the current-generation sensor and the one you want. You can free-air calibrate it or run the factory resistor calibration, whichever fits how you work. If you want to log the AFR somewhere else too, you can wire in a 0-5V analog output or an RS232 serial output.\u003c\/p\u003e\n\n\u003ch4\u003eHow It's Different From the 30-0300\u003c\/h4\u003e\n\n\u003cp\u003eThis is the main thing to get right before you buy. The 30-0300 X-Series gauge sends its data over AEMnet. This one drops AEMnet and uses OBDII pass-through instead, pulling AFR through the factory CAN-bus. The default OBDII CAN address works on most cars right out of the box, and if yours needs a different one, you can change the address right from the buttons on the gauge face. If your setup is built around OBDII and a piggyback or open-source tune, this is the one you want. If you're on an AEMnet setup, you want the 30-0300.\u003c\/p\u003e\n\n\u003ch4\u003eSpecs\u003c\/h4\u003e\n\n\u003cul\u003e\n    \u003cli\u003eReads AFR off the factory CAN-bus via OBDII pass-through\u003c\/li\u003e\n    \u003cli\u003eBosch 4.9LSU wideband sensor included\u003c\/li\u003e\n    \u003cli\u003eFree-air or factory resistor calibration\u003c\/li\u003e\n    \u003cli\u003eOptional 0-5V analog or RS232 serial output for logging\u003c\/li\u003e\n    \u003cli\u003eProgrammable OBDII CAN address via the gauge face buttons\u003c\/li\u003e\n    \u003cli\u003eWorks with HPTuners, EFILive, DashDaq, and other tuning systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n    Universal \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\nPatented X-Digital Technology, OBDII pass-through, Bosch 4.9LSU wideband UEGO sensor, factory O2 calibration or free-air calibration, compatible with vehicle\/system voltages up to 16V, optional 0-5V \u0026amp; RS232 outputs, 52mm gauge diameter, 0.825 gauge depth, auto-dimming display, user-configurable display settings.\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\nConnect the gauge to the vehicle's OBDII port using the provided OBDII cable.
