Fits Most Models
30-4110
Overview:
The AEM Digital Wideband Controller AFR Gauge Kit is a precision air/fuel ratio monitoring solution designed for a wide range of vehicles. Featuring a digital LED display combined with a sweeping LED needle that changes color to indicate AFR shifts from rich to lean, this gauge provides clear and immediate feedback for tuning and engine management. Ideal for performance enthusiasts, tuners, and daily drivers alike, it helps you maintain optimal engine performance and efficiency by delivering accurate, real-time air/fuel ratio data.
Its compact 52mm (2-1/16") gauge housing fits most standard gauge pods and can be remotely mounted almost anywhere in your vehicle’s interior. The kit includes everything needed for installation and customization, making it a versatile choice for most applications.
Key Features:
This AEM wideband controller gauge kit combines advanced sensor technology with user-friendly design and customization options:
- High-precision 4.9 LSU wideband oxygen sensor with faster light-off time and lower current draw compared to previous 4.2 LSU sensors.
- No free-air sensor calibration required, ensuring consistent accuracy without the need for recalibration.
- Digital LED display with a sweeping LED needle that changes color to visually indicate air/fuel ratio changes from rich to lean.
- Compact 52mm (2-1/16") gauge housing designed to fit most standard gauge pods and allow flexible mounting locations.
- Interchangeable black and white faceplates included for customizable gauge appearance, featuring a black Lambda faceplate and black and white Air/Fuel Ratio faceplates.
- Interchangeable black and silver bezels included to match your vehicle’s interior styling.
- 0-5V analog output compatible with most data loggers and engine management systems, covering a 10-20 AFR range.
- Weld-in bung included for secure sensor installation.
- Unique connector design for the 4.9 LSU sensor, ensuring proper compatibility and preventing sensor interchange with older models.
Construction & Design:
The gauge features a robust 52mm housing that balances compact size with clear visibility. The digital LED display and sweeping needle provide intuitive, at-a-glance AFR monitoring, while the color-changing needle enhances situational awareness during tuning or spirited driving. The included bezels and faceplates allow you to tailor the gauge’s look to your vehicle’s interior, ensuring a professional and integrated appearance.
The 4.9 LSU sensor technology offers improved durability and responsiveness, with a faster light-off time that reduces warm-up periods and enhances accuracy right from startup. The sensor’s design also reduces electrical current draw, contributing to overall system efficiency.
Installation & Fitment:
This gauge kit is designed to fit most vehicle models, making it a versatile choice for a wide range of applications. The 52mm gauge size fits standard gauge pods, and the gauge can be remotely mounted virtually anywhere inside the vehicle for optimal visibility and convenience.
No free-air calibration is ever required, simplifying installation and maintenance. The kit includes a weld-in bung for secure sensor mounting, and the sensor connector is uniquely designed to ensure proper installation with the 30-4110 controller gauge.
