GlowShift 10 Color Digital Dual Boost & Wideband AFR Kit
The GlowShift kit combines a dual boost/vacuum gauge with a wideband AFR gauge in a compact 2-1/16″ (52mm) housing. It features 10 selectable solid color modes plus 2 color cycle modes, allowing each display to be color-coded for quick reading under driving conditions. A black face, tinted lens, and aluminum housing provide a professional look for performance dashboards. The dual gauge setup enables simultaneous monitoring of turbo or supercharger boost and air-to-fuel ratio, with self-calibration at startup to ensure reliable readings. This kit is suited for enthusiasts who want color-customizable, space-efficient instrumentation with straightforward installation through included sensors and wiring. The data-logging output supports later tuning and analysis. Sections of the display can be tailored to user preference, aiding quick interpretation during street or track sessions.
Wideband UEGO Air/Fuel Ratio Gauge 52mm (2-1/16”)
This 52 mm wideband gauge centers on accuracy with a 4.9 LSU sensor and a 0-5V analog output suitable for data loggers and most engine management systems. The LED display changes color with the AFR value to provide quick, at-a-glance feedback. The bezel and faceplates offer black and silver options for multiple color combinations that can match your cockpit color scheme. The gauge is designed for broad compatibility in instrument pods and remote mounting. It emphasizes fast and precise AFR readings, enabling timely adjustments to protect engine health and optimize performance while balancing fuel economy in varied driving conditions.
AEM X-Series Gauges Combo Set of 3
Designed for pro-level monitoring, this AEM X-Series trio includes a Wideband AFR, Turbo Boost, and Oil Pressure gauge. The kit prioritizes compact installation with a shallow 0.825″ depth, allowing mounting in tight dash pods. It features an advanced display with a larger central LED and multiple outer LEDs, along with user-selectable warnings. Data outputs include analog and CANbus for EMS or data loggers, making it a robust choice for tuners who rely on integrated data streams and multi-gauge coordination during high-performance driving and tuning sessions. This bundle provides a complete view of engine health and boost behavior in one panel.
AEM 52mm X-Series Gauge Kit Wideband & Boost
This kit pairs a wideband AFR gauge with a boost gauge in a 52 mm package. The wideband AFR provides accurate air/fuel readings with a high-contrast display, while the boost gauge delivers real-time pressure data to help manage turbo or supercharger performance. The kit emphasizes a low-profile, unobtrusive form factor that integrates cleanly into most cockpits. AEM’s X-Series design supports easy data collection and monitoring, making it a practical choice for builders who need dependable AFR and boost information alongside optional lanyard access for quick mounting and safe handling on track days or spirited drives.
AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller
The AEM 30-0300 X-Series introduces an advanced wideband controller with the latest X-Digital technology, delivering enhanced accuracy and faster response times for AFR readings. It provides multiple outputs including 0-5V analog, RS232 for data logging, and CANbus through AEMnet for comprehensive data integration. The controller’s display is visually striking, with a seven-segment center display that is notably larger than earlier models. This product is suited for precision tuning and systems that rely on high-fidelity AFR data to optimize performance and protect the engine under dynamic load changes.
Buying Guide: Key Purchase Considerations
- Display quality and readability: Choose gauges with high-contrast LEDs and adequate size to read at a glance, especially while driving.
- Sensor and sensor support: Confirm sensor accuracy, response time, and compatibility with your engine management system or data logger.
- Output options: Determine which outputs you need (0-5V, CANbus, RS232, data logging) for your existing tuning setup and ECU.
- Installation footprint: Consider gauge depth and pod space; low-profile designs fit tighter cockpits.
- Color customization: If aesthetics matter, prioritize kits with multiple color modes or bezels to match your vehicle’s interior.
- System integration: For multi-gauge kits, ensure the data outputs and mounting options allow synchronized readings across gauges.
- Durability and calibration: Look for self-calibration features and build quality (housing material, lens, and resistance to vibrations).
- Warranty and support: Review manufacturer support policies, especially for data logging and sensor longevity.
These considerations help tailor a wideband boost gauge setup to diverse needs—from street tuning to track-day data logging. Each option presented offers a balance of readability, data access, and install flexibility, enabling drivers to monitor air/fuel ratios and boost pressure with confidence and precision.
