⚡ At a Glance
- • Display Readout: Large seven-segment centre display with auto-dimming for improved visibility
- • Best for: Engine tuners, performance workshops and experienced enthusiasts needing AFR logging
- • Not ideal for: Casual drivers seeking a simple, plug-and-play dash gauge without tuning knowledge
Wideband UEGO AFR controller with faster response time and multiple data outputs. Designed for accurate tuning and dyno analysis.
Clear, easy-to-read feedback – with a large seven-segment centre display
A bold seven-segment numeric centre display sits behind a visually striking faceplate, and auto-dimming keeps the readout legible in changing light. The larger display prioritises numeric AFR values over secondary graphics for instant interpretation.
Immediate AFR readings let tuners spot lean or rich conditions quickly and make faster on-the-fly adjustments during tuning sessions.
Reliable logging and control – thanks to 0-5V, RS232 and AEMnet outputs
Analogue 0-5V, RS232 serial and AEMnet CANbus outputs provide multiple routes for feedback control and data logging. These outputs allow direct connection to ECUs, dataloggers and CAN-enabled logging networks.
Direct connectivity simplifies closed-loop tuning and long-term data capture, making it straightforward to correlate AFR with other engine parameters.
More accurate, safer tuning – with faster response time and X-Digital wideband technology
X-Digital wideband technology increases the number of values reported while a faster response time reduces latency during rapid AFR changes. The gauge also accounts for dead time on inertia when used on a dyno.
Denser, quicker readings reveal transient conditions that slower units miss, helping to protect engines and deliver a more accurate tune.
