Innovate Dual Lambda Air Fuel Ratio O2 Gauge | 3891

The Innovate DLG-1 is a dual wideband air/fuel ratio system designed to monitor both exhaust banks simultaneously from a single 52mm gauge. Built around Innovate’s DirectDigital™ wideband technology, it provides high-accuracy AFR data for V-type and boxer engines where balanced fueling across cylinders is critical.

By integrating two sensors into one display, the DLG-1 simplifies tuning and diagnostics while delivering real-time feedback for performance and engine safety.
