Wideband lambda sensor
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

Techedge 3B1 premium wideband system
!

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 auxilliary inputs for analogue sensors, thermocouples and speed sensor and onboard memory for datalogging 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 datalogger
  • 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
!

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 datalogger
  • 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).

Please note that the 3H1 is available for special order only.

LA1 wideband display
!
The LA1 is Tech Edge'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 Tech Edge 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 Tech Edge version 2.0 and 3.0 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
  • Thin - 13 mm (½"). Attach it to your dash with double sided tape.
  • Big Screen - 45 x 20 mm (0.8 x 1.8").

Bosch LSU 4.2 wideband sensor
!
widebandsensor

Bosch 7200 series 5-wire wideband lambda sensor, fully interchangeable with "7057" sensors.

Please note this is a sensor only and must be used in conjunction with a wideband controller such as our techedge systems.  Also suitable for replacing faulty sensors on many other wideband systems such as the Innovate LC-1

Lambda sensor boss and bung
!
bossnbung130

Stainless steel lambda sensor boss and bung.  Standard M18 thread for use with most sensors.

Weld on the boss and screw in your lambda sensor.  Should you wish to remove your sensor for any reason just screw the bung in to block the hole.

USB-serial adaptors
!
USB-serial adaptor for computers lacking a serial port.

Many new laptops and PCs do not come with a serial port.  These adaptors plug into a USB socket and allow you to connect up to your ECU. 

Many cheaper adaptors give problems, these adaptors use a premium FTDI chipset and tested to work with Megajolt, Megasquirt and Emerald ECUs.
