Wideband lambda systems

A wideband lamda sensor is an essential tool in your tuning arsenal. Whether you just want to run your ECU in closed loop mode for economy reasons, just want an additional diagnostic tool or perhaps you want to tune your engine from scratch a wideband system

SLC2 Pure-Plus2 wideband and datalogger

SLC2

Accuracy of 0.01 Lambda
Built-in 4-digit display
Onboard memory for 2.9 hours of data logs at 25Hz
USB connectivity
Programmable Linear Output
Programmable Narrowband Output
Supplied with new Bosch LSU wideband sensor
Small size and low weight, the controller is roughly the size of a pack of playing cards.
Winlog data logging and analysis software

Sensor inputs:

Wideband lambda
RPM
Dual-axis accelerometers (-4 to +4g)
Two 0-5v analogue inputs (channels shared with accelerometers)
Boost/Vacuum
Exhaust Gas Temperature
Air intake temperature
Coolant temperature
Fuel pressure
Oil pressure
Battery voltage

Air temperature sensor

EGT sensor

Boost sensor

Boost/MAP sensor

Oil pressure sensor

Please note that SLC Pure-Plus2 only supports external gauges attached using the programmable analogue outputs and does not support the digitally attached Techedge LA1 and LX1 gauges.

Techedge 2J2 wideband system

TE2J2

The new 2J2 wideband improves on the incredibly popular 2J1 system. Despite the low cost the 2J2 wideband offers functionality only usually found on much more expensive systems. The base package includes the a Bosch LSU4.2 7200 sensor and all cables. You may like to consider the LA1 or LX1 display for use with the 2J2.

Accuracy within +/- 0.1 AFR over AFR 11 to 17.
Configurable differential wideband 0-5 Volt output for use with your ECU or 3rd party display.
2 serial port sockets for connection to your PC, data-logger or gauge
Simulated narrowband output.
2 analogue 0 to 5 Volt inputs sampled at up to 40/sec.
RPM input from Tacho or ECU.
PULSE input from speed sensor
Uses new Bosch LSU 4.2 7200 sensor.
Auto-cal button calibration with sensor in free-air.
10.5 to 19.5 Volt DC operation.
Small size and low weight, the controller is roughly the size of a pack of playing cards.

Techedge 3B1 premium wideband system

3B1

The 3B1 wideband system is our premium wideband system for single-wideband installations. Designed for permanent installation it comes in a robust gold anodised extruded aluminium case.

Extensive auxiliary inputs for analogue sensors, thermocouples and speed sensor and on-board memory for data-logging all in the one box. The package includes the latest Bosch 7200 sensor. You may like to consider the LA1 or LX1 display for use with the 3B1.

Accuracy within 0.1 AFR (Lambda +/- 0.005).
Simulated narrowband output (10 bit PWM signal & configurable too).
RPM input from Tacho or ECU for logging.
Socket for connection to your PC or data-logger
1 MB of on-board logging memory
Configurable wideband output up to 8 Volt output (12 bit DAC accuracy), defaults to 0-5 Volt.
6 analogue inputs configurable as:
- up to 6 of 0 to 5 Volt inputs (4 differential, 2 single ended).
- up to 4 of thermocouple inputs (all differential) .
Additional pulse input channel (for vehicle speed, etc.)
10.5 to 19.5 Volt DC operation
Supports LSU 4.0/4.2 (Bosch 6066/7057/7200 family) as well as LSU 4.9 and NTK (L1H1/L2H2) sensor (requires NTK sensor cable).

Techedge 3H1 dual wideband system

3H1

At last, a twin input wideband system. The 3H1 features all the functionality of the 3B1 wideband system but with a pair of lambda sensors. Ideal for monitoring both banks of a "Vee" engine, sensing pre/post catalyst or monitoring engines such as the A-series where certain cylinders have a propensity to run leaner/richer than the rest.

The package includes a pair of the latest Bosch 7200 sensors. You may like to consider the LA1 or LX1 displays for use with the 3H1.

Accuracy within 0.1 AFR (Lambda +/- 0.005).
1 MB on-board logging memory
Socket for connection to your PC or data-logger
Configurable wideband up to 8 Volt output (12 bit DAC accuracy).
6 analogue inputs configurable as:
- up to 6 of 0 to 5 Volt inputs (4 differential, 2 single ended).
- up to 4 of thermocouple inputs (all differential) .
Additional pulse input channel (for vehicle speed, etc.)
10.5 to 19.5 Volt DC operation.
Simulated narrowband output.
RPM input from tacho or ECU for logging.
Supports LSU 4.0/4.2 (Bosch 6066/7057/7200 family), LSU 4.9 as well as NTK (L1H1/L2H2) sensor (requires NTK sensor cable).

LA1 wideband display

The LA1 is TechEdge's Circular Wideband Lambda Display. In a standard 52mm gauge pod it features a 30 bar bi-colour (both red & green) peripheral display, and central 4 digit display.

Digital (RS232) connection to TechEdge WBo2 units.
Field re-programmable. Firmware can be updated.
Has two buttons to control the display and logging functions.
Range of the outside LEDs can be configured to cover small or large ranges.
Can be used as a display for other WB units & instruments including ones with analogue outputs.
Three (optional) programmable outputs

LX1 wideband display

The LX1 will work with all our Techedge controllers and, as it's field re-programmable, can be upgraded and enhanced in the future.

LCD - Can be used in direct sunlight
Backlit - Can be used at night
