Stack Pro-Control Wideband Lambda Gauges

Stack Pro-Control Wideband Lambda Gauges are the ultimate tuning aids. Dual digital and radial LED displays provide an accurate real-time readout of either the air/fuel ratio or lambda (user-selectable). A 0-4 V analog output can be connected to a data-logger or to an ECU to provide real-time, closed-loop feedback for improved mapping. These Stack gauges come complete with a wiring harness and include a Bosch sensor. Select the gauge face color you prefer.

Additional features:

* Programmable alarm to warn of dangerous lean condition
* Peak recall of leanest value during last run
* Suitable for all fuel types with AFR from 6:1 to 20:1 (not recommended for leaded fuel)
