AEM’s X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0334) provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN-bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune. The 30-0334 X-Series OBDII Wideband Gauge is validated to work with EFILive, HPTuners and DashDaq software. The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and Bosch 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration. Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger. This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.

OBDII CAN-bus OUTPUT

The OBDII output simulates an auxiliary ECU signal when plugged into a vehicle’s OBD port, which requires a unique address from the other ECUs already on a vehicle’s network. AEM’s default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary. However, AEM has provided OBDII address programmability through the buttons on the gauge face if a different address other than the default address is required, allowing users to program ECU #, Parameter Identification (PID), Message Identifier, and Bit Rate.

PATENTED X-DIGITAL TECHNOLOGY – It’s The Fastest

X-Series Widebands are the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.* The controller’s high speed, patented, X-Digital technology (Patent 9,575,030) ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

WHY RESPONSE TIME MATTERS

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Digital technology reduce deadtime and can improve the performance of your vehicle through more accurate AFR tuning.

FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT’S YOUR CHOICE!

X-Series Wideband Gauges and the X-Series Inline Controller support the popular Bosch 4.9LSU sensor, and can utilize both the factory calibration resistor and free-air calibration methods. This allows users to take advantage of the precise factory resistor calibration when a sensor is new but then allows for free-air calibrations if the user desires when the sensor ages.** It’s the perfect marriage of simplicity and accuracy!

WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?

AEM’s Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

WHY USE A WIDEBAND AIR/FUEL CONTROLLER?

Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.

CAN I CHANGE THE AEM UEGO SENSOR’S CONNECTOR?

No. There is a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output. * Independently tested at 360° Product Testing (results reported on August 31st, 2015) against 17 competitor wideband UEGO Air/Fuel Controllers. AEM X-Series Inline with Bosch 4.9LSU wideband sensor and AEM X-Series Wideband UEGO AFR Gauge with Bosch 4.9LSU sensor recorded the fastest response times. ** Wideband UEGO sensors are wear items and their lifespan is determined by many factors including contamination from leaded fuels, automotive fluids, particulates, mechanical or thermal shock and from being unheated and exposed to the exhaust stream. Free-air calibration may correct drift as a sensor ages, but it is recommended that they are replaced as part of your vehicle’s maintenance program. When performing free-air calibration, please follow the procedure outlined in the instruction manual.

The AEM Water/Methanol Injection System Advantage

Water/methanol injection for forced induction (turbocharged or supercharged) gas-powered race engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation. This allows racers to reliably increase boost and advance ignition timing—without using high-octane racing fuel—for power gains of up to 20%. AEM’s Water/Methanol Injection Systems utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system. AEM offers two different water/methanol controller designs for gas vehicles:

• One is boost dependent for forced induction vehicles up to 35 PSI of boost (kit PN 30-3300). The Boost Dependent controller has an on-board manifold absolute pressure (MAP) sensor with a molded-in nipple for a boost hose pickup.
• The second controller (Kit PN 30-3350) features a multiple input design that enables users to install AEM’s Water/Methanol Injection Kit on ultra-high boost vehicles (above 35 PSI) using a 0-5v voltage-based external MAP sensor.

Key Features :

• Boost Dependent and Multi-Input (0-5v/frequency) progressive controller designs feature large adjustment knobs, integrated plug for harness connection, integrated fuse, covered status light and test button for enhanced splash resistance and mounting tabs.
• Wiring harness is terminated with a positive-lock connector on one end with color-coded wires to ease installation, integrated pump ground circuit and additional wire for optional on/off fluid solenoid.
• “Boost Safe” failsafe output included (for complete failsafe under all conditions, see our Water/Methanol Failsafe Device)
• Heavy-duty high-pressure injection pump features integral fittings, a Santoprene diaphragm and EPDM seals to resist corrosion. Our pump maximizes line pressure for optimum atomization and its quiet, smooth operation is almost undetectable
• Precision-machined billet-aluminum injector with integral check valve
• Three interchangeable injector nozzles to cover a wide variety of HP levels (250cc/min, 500 cc/min & 1,000cc/min)
• 1.15 gallon tank with anti-starvation reservoir, integral conductive low-fluid sensor and positive lock connector (tank-less systems available)
• 20 feet of injection tubing included
• LED dash light for system status and low fluid warning

This is for the kit that comes with bare essentials, NO tank or fluid level sensor is included. Note from AEM : For optimum results, all Water/Methanol Injection Systems and gauges should be run with an AEM inline filter (AEM part # 30-3003)
