AEM X-Series OBDII Wideband AFR Controller Gauge

Wideband air-fuel data in your HP Tuners logs, with no extra wiring. The AEM X-Series OBDII gauge (part 30-0334) puts its AFR reading onto the vehicle's CAN bus, so VCM Scanner can log it right alongside the factory channels. It is the OBDII version of AEM's X-Series wideband and is validated to work with HP Tuners VCM Suite.

How it works

• Plugs in through the included OBDII pass-through connector. Your MPVI interface plugs into the gauge's pass-through port.
• The gauge acts like an auxiliary module on the CAN network. AEM's default settings work on most vehicles; the ECU number, PID, message ID and bit rate can be changed from the gauge face if needed.
• Requires a CAN-based vehicle.

Specifications

• Bosch LSU 4.9 wideband sensor included
• Display range 8.0:1 to 20.0:1 AFR (0.55 to 2.00 lambda); reads in AFR, lambda or O2 percent
• Optional 0-5 volt and RS232 outputs for other data loggers (requires wiring)
• Works on systems up to 16 volts
• 52 mm gauge, 0.825 inch body depth, auto-dimming display
• Black bezel and black dual-face faceplate included; silver bezel and white face sold separately (30-0300-ACC)
• Free-air calibration from the faceplate buttons to correct for sensor aging

Good to know

• AEM's X-Digital technology is built for fast response, which tightens closed-loop fuel control.
• Wideband sensors are wear items. Leaded fuel, fluids, debris and shock shorten their life.
• The sensor connector carries a laser-etched calibration resistor. Don't modify it.
