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.

• Controller gauge and hardware sold without wideband sensor
• No free air sensor calibration required - ever
• 0-5v analog output (10-20 AFR range only)

AEM's legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED "needle" that changes colors as AFR changes from rich to lean. NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014. Instructions for the 30-4100 will still be available in the Instructions tab after this change. 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. WHAT IS FREE-AIR CALIBRATION? Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated and never require free air calibration!

Racers with high compression naturally aspirated engines or boosted engines who are looking for an alternative to boost-dependent water/methanol injection controllers have a solution in AEM's Multi-Input WMI controller. The multiple input design enables users to install AEM's Water/Methanol Injection Kit on both high compression naturally aspirated vehicles (NA) via the MAF/IDC settings and ultra-high boost vehicles (above 40 PSI) using an external MAP sensor. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency-based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF. The Multi-Input controller is offered in three kits; a one-gallon tank kit with a single injector for gas engines (PN 30-3350), a tank-less kit with a single injector (PN 30-3352), and a five-gallon tank kit with two injectors (PN 30-3351) for HD high-output gasoline applications.

These new controllers retain the "Boost Safe" injection failsafe system, which is an output that will activate if there is a short, loss of continuity or high or low voltage or low fluid condition, allowing users to define their failsafe strategy from something as simple as flashing a warning light to more advanced strategies like pulling boost or ignition, or switching fuel maps on a standalone engine management system.Simplified WiringThe new wiring harness is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. An integrated Pump Ground circuit is included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.Improved Injector Flow Rate & Nozzle SizesAEM's engineers spent extensive time revamping the controller's flow control strategy for a more linear flow output delivery.

Auto enthusiasts who have forced induction engines, high RPM engines or run nitrous oxide are aware of the compromises that come with using inductive coils instead of converting to a Capacitive Discharge Ignition system (CDI). While inductive coils deliver a long spark duration with simplicity, they lack the energy to adequately ignite the mixture in the combustion chamber of a highly modified performance vehicle. Conversely, CDIs deliver an intense burst of spark energy, but with practically no spark duration, which makes having the proper air/fuel mixture in the combustion chamber paramount for best performance. This compromise ends with AEM's High-Output IGBT "Smart" Inductive Coils.

• Deliver CDI-like spark energy-No CDI Module needed
• Up to 40kV Output Voltage, without using a CDI
• Incredibly long spark duration, up to 2.9mS
• Can be mounted directly to the Engine
• Cost less than aftermarket LS1 coils
• Massive Spark Energy, up to 103 mJ
• Can be mounted almost anywhere
• Weather and Shockproof design

Any enthusiast running boost, nitrous or high RPMs is aware of the trade-offs associated with inductive coils versus converting to a capacitive-type discharge ignition system (CDI). While inductive coils deliver a long spark duration, they lack enough energy to light off the combustion chamber of a modified high-performance vehicle. In contrast, CDIs delivers intense energy but with inadequate spark duration, making the proper mixture in the combustion chamber critical for best performance. This tradeoff ends with AEM's High-Output "Dumb" Inductive Coils, the first inductive coils that deliver CDI-like spark energy and voltage, and the long spark duration necessary for vehicles running forced induction and nitrous.

• Robust construction allows them to be mounted almost anywhere
• CDI-like spark energy without the need for a CDI
• Heavy-duty, weatherproof and shockproof design
• Available for vehicles with external igniters
• Incredibly long spark duration, up to 3.2mS

Swapping to a coil-on-plug ignition set-up can eliminate dwell time issues that can be problematic in stock ignition systems, and AEM's Ignition Coil Drivers are the most affordable way to drive coils in a coil on plug set-up. AEM's Ignition Coil Drivers are designed for driving high-power, dwell-controlled two-wire ("dumb") coils commonly found on performance engines. Our Three- and Four-Channel igniter coil versions can be used as a replacement for a stock coil driver or when converting to coil-on-plug in engines that do not need the extra spark energy from a CDI, or do not have the mounting space for a CDI like on ATVs, snowmobiles, motorcycles, and other Powersports applications.

• Three- and Four-Channel Ignition Coil Drivers are ideal for ATV's, motorcycles, snowmobiles and racing vehicles with space limitations or those that do not require additional voltage generated by a CDI
