AEM’s Bosch 4.9LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM Digital Wideband UEGO Air/Fuel Controller Part Number 30-4110. These sensors have 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. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller. Features:

• Accurate to 0.1 AFR
• Never requires free-air calibration when used with an AEM Controller and connector plug.
• Specifically designed for use with AEM Wideband UEGO controller Part Number 30-4110
• Replacement sensor only

Replacement Sensor for the following AEM Wideband Controllers:

• 30-4110 – Digital Wideband UEGO Gauge
• 30-0300 – X-Series Digital Wideband UEGO AFR Gauge
• 30-0310 – X-Series Inline Wideband UEGO AFR Controller

All other AEM Wideband Controllers please refer to the 30-2001 Bosch LSU 4.2 Replacement Sensor

AEM’s Universal Core & Accessory Wiring Harnesses simplify the installation of an Infinity ECU on any 4-, 6- or 8-cylinder application with an Infinity-supported crank/cam timing configuration.

The Universal Core Harness combines injector sub harnesses with ignition timing sub harnesses for every type of MAG and Hall Effect timing configuration, allowing racers to get an Infinity-tuned racecar wired quickly and accurately. Idle motor sub harnesses for Ford and GM are available for easy integration onto Ford & Chevy Small Blocks and Big Blocks. An ignition adapter sub harness for AEM’s Single Channel Coil Driver is available for triggering an inductive coil directly or a single-channel capacitive discharge ignition (CDI). Ignition sub harnesses for the AEM EPM and other popular ignition systems are also available.

COMPREHENSIVE CORE HARNESS DESIGN

AEM’s Universal Core V8 Wiring engine harness (PN 30-3809) is terminated with Infinity Series 5 ECU connectors, power/ground leads and an OEM power distribution block with 5 relays and 7 fuses. Special care was taken to build redundancy into the power distribution system to increase overall reliability.

High-Performance DTM-Style connectors terminate the leads for dual UEGO wideband air/fuel ratio sensors, wheel speed sensors, AEMnet (AEM’s CAN bus), dual 8-pin auxiliary ports, cam & crank, idle, injectors and coils sub harnesses. High-Performance DTM-Style connectors and pins are included for the auxiliary ports. Flying leads are included for permanent and switched power, manifold pressure (MAP), oil pressure, fuel pressure, air temperature, coolant temperature, and throttle position.

The wiring is covered in an automotive-grade loom for enhanced longevity and the power/ground leads are heavy-duty serrated versions to ensure the best connection. A firewall grommet is included for a clean pass-through. All wires and connectors are labeled for ease of installation.

INJECTOR SUB HARNESSES

Injector adapter harnesses are available for Ford and GM engine injector locations and cylinder numbering. They connect to the Universal V8 Core Harness via a High-Performance DTM-Style connector and include the popular/common Bosch EV1-style connectors for the fuel injectors. These harnesses include labels for ease of installation and are covered in an automotive-grade loom for longevity.

CAM/CRANK TIMING SIGNAL HARNESSES

AEM has made the task of configuring and wiring cam/crank signals as easy as the snap of a High Performance DTM-Style connection. Timing sub harnesses are available for:

• MAG Cam/Hall Crank (PN 30-3805-05)
• AEM EPM 35″ Leads for Front Mounted Distributor (PN 30-3805-19)

High quality shielded wiring is used to virtually eliminate EMI and the flying leads for crank position, cam position, power, and grounds are labeled for ease of installation.

AEM’s Infinity Series ECU stand alone management systems deliver a high end Motorsports output at a price that makes it attainable for a sportsman racer. The Infinity ECU delivers state-of-the-art programmable EFI control capabilities with airflow-based tuning models. System installation is more simplified and the tuning process is speed up by eliminating many of the setup requirements necessary in previous generation ECUs.

AEM Tru-Time Adjustable Cam Gears increase horsepower and torque without having to change the camshaft(s) and are must-have items for engines that are milled, forced induction, high compression and/or utilizing aftermarket competition cams. Tru-Time cam gears enable users to match cam timing with their vehicle’s tuning state by advancing or retarding the cam profile(s) in one-degree increments via true laser-etched markings. Precision-cut gear teeth ensure no premature wearing of the cam gear’s belt surface and AEM’s anodizing on the adjustable cam gear’s teeth is lab-test proven as the hardest anodizing process on the market. AEM Tru-Time Adjustable Adjustable Cam Gears are available in a multi-spoke, five-bolt designs.

Features

• Increase horsepower and torque without any cam changes and are ideal for heavily modified engines
• Grade-8, six-point hex bolts stand up to repeated adjustments and feature an integral washer flange for greater load distribution
• True laser-etched markings on the leading edge of the gear allow for quick, accurate adjustments
• CNC-machined from 6061-T6 billet aluminum
• Belt surface is hard anodized
• Recommended cam gear settings included
• Manufactured and assembled in the USA

The PUD-8 Eight Channel Power Distribution Unit receives its commands directly from a Vehicle Control Unit like the AEM EV VCU200, VCU300, or other VCUs with CAN transmission capability, eliminating the need to create complicated logic programming in the PDU. This makes them straightforward to configure, easy to troubleshoot and negates the need to have dedicated spares for motorsports electric vehicles, due to their ability to be used interchangeably. The PDU-8 Eight Channel Power Distribution Unit features:

• Four 20A and four 10A high-side 12V outputs for activating/deactivating various switched devices Connect up to eight units for a total of 64 channels
• Smaller modules which allow for multiple units to be deployed nearer the systems they control, simplifying wiring and reducing weight
• CAN-commanded PDU, no logic programming required for PDU operation
• PDU ID is defined by wiring at the connector, allowing units to be fully interchangeable
• A small size and light weight
• Individual channel current draw and fault states are reported back to the VCU
• Fully-sealed, waterproof billet-aluminum enclosure

Note: The PDU-8 interfaces with the VCU200 and VCU300 and with the AEM Infinity ECU as of firmware version v96.5. It does not work with Series2 ICE management system.
