Wide-band Air-Fuel (Lambda) Gauge
This is the ultimate tuning aid! Dual digital and radial LED displays provide accurate real-time readout of either air/fuel ratio or lambda (user-selectable). A 0-4Volt analogue output can be connected to a data-logger or to an ECU to provide real-time closed-loop feedback for improved mapping. Supplied complete with wiring harness and includes Bosch sensor. User-selectable Air/Fuel or Lambda real time display Programmable Alarm warns 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 0-4 Volt Data Logger or ECU output
Wide-band Air-Fuel (Lambda) Gauge
ST3401
M18x1.5
Includes Bosch sensor as standard:

Sensor has M18x1.5 mm thread that can be mounted to the exhaust system via a lambda sensor welded bung. Sensors thread will also will fit narrowband sensor plugs currently on exhaust systems.

Bosch Lambda Sensor LSU 4.2 Specifications

Gauge comes complete with wiring harness and associated sensor.

These precision auxiliary instruments combine digital microprocessor accuracy with a high-precision stepper motor needle movement, to provide a new level of accuracy and reliability in 52mm gauges. They combine the durability and readability of 270° mechanical gauges with the easy installation and safe operation of conventional electric gauges.

The 270° dialface together with the new white LED backlighting and illuminated needle ensure excellent readability day or night.

52mm diameter Fast, smooth stepper motor needle drive 270° full sweep movement for excellent readability Remotely mounted solid-state sensors keep hazardous fluids in the engine compartment Better than 2% accuracy All-electronic design for maximum reliability White LED through-the-dial backlighting White LED illuminated needle

All gauges come complete with wiring harness and associated sensor except fuel level and voltage gauges.

These low-priced electrical auxiliary instruments feature advanced 90° air-core movements and simple 3-wire installation. Electrical sensors keep hazardous fluids in the engine compartment. White LED backlighting and illuminated needle ensure excellent readability day or night.

52mm diameter 90° sweep No large connectors and tubing coming out the back. Can be mounted in more unusual positions without connections showing. Easier to install in tight areas. Easier to install a great distance from the item being measured. Stops fluids from entering the passenger compartment.

This range of gauges have been specifically designed for vehicles with no or low powered electrical systems.

52mm diameter Bronze bourdon tube 270° sweep movement Mechanical gauges do not require 12V power to operate. They make direct physical contact with the item they are reading. They do this through tubing or lines, which eliminates the need for electric signals. Ideal for vehicles that operate on voltages other than 12V, with no voltage at all (magneto applications) or operate on a battery with no generator. Note: 12 volt supply is needed if backlighting required.
