WBo2 2C0B Wideband (updated 2010)

The 2C0B is Tech Edge's miniature wideband product. It adds two analog channels and an additional Vss/Pulse channel. It was introduced in December 2009, superseding the original 2C0. It now works with the newer LSU 4.9 sensor (the 17023 LSU-4.9 is just almost the same price as the 7200). We designed it for small size and is therefore very suitable for motorcycle usage.

2C0B is suitable for all wideband applications where the extra logging capabilities of the larger units is not required. 2C0B uses the larger M168 processor (~12 MIPs) and has more evolved pump cell control technology as found in the version 3 WBo2 units. It has a 12 bit differential wideband output (WBlin+ & WBlin-).

note: 2C0B works with the LSU 4.0, 4.2 & 4.9 sensors . This controller is the versatile upgrade to the economy 2J1 model. The previous 2C0 model lacked the two voltage inputs and the VSS/pulse input this model has.

The 2C0 is housed in a tough, flame retardant, black ABS plastic case. It is small, 90 x 50 mm (ie. credit card sized) and just 25 mm high. The green connectors protrude an extra 10 mm outwards. Click on the images for larger pop-up versions.

The unit has 5 connection points :

  • wideband cable on Circular Metal socket.
  • Power & Ground White Molex socket.
  • I/O on two Green connector blocks.
  • RS232/Display output on two black 8 pin RJ45 sockets.

Tech Edge  2C0B Features

  • Supports Bosch LSU 4.0/4.2/4.9 family.
  • Accuracy to 0.1 AFR (Lambda +/- 0.005).
  • Differential 12 bit (hardware) WBlin 0-5 Volt output.
  • two configurable 9.5 bit 5 Volt analog outputs :
    1. NBsim narrowband 0-5 Volt output.
    2. SVout compatibility 0-5 Volt output.
  • RPM input from Tacho or ECU for logging.
  • Two 0-5 Volt analog inputs for logging.
  • Vss (like RPM) speed (or pulse width) input.
  • 10.5-19.5 Volt DC operation (3A max).

The following are changes over the original 2C0 :

  • Works with LSU 4.9 sensor
  • Two additional 0-5 Volt inputs
  • Additional Vss/Pulse measuring input
  • Two RJ45 serial ports (for display + PC, etc.)
  • Black case (original 2C0 used a grey case)
  • The same price as the original, but with more features!

Note: The 2C0B needs a cable between the controller (2C0B) and the selected sensor - different sensors have different connectors (and therefore different cables). Cables are available in various lengths. 2C0B controllers come with power & RS232 cables and green connectors. A display is optional.

2C0B Connection Overview

The image at left shows how 2C0 is connected to other WBo2 wideband components. Some popup images of parts are available.

Clockwise from the bottom right, the LSU (UEGO support may be offered later) sensor is connected via the sensor cable (comes in various lengths for different applications). The sensor cable's circular 8 pin connector mates with the 2C0 unit. 2C0 needs a source of power provided by the two pin power cable.

On the back of the case are an 8 pin (RJ45), and a 6 pin (RJ11) connector for PC RS232 connectivity (config & logging) and for connection to an intelligent display. The top of the case carries three status LEDs that show power (GREEN), heater (AMBER) and operational (RED) status.

The side of the case carries a 6 pin green unpluggable connector with voltage outputs and RPM logging inputs.

The connectors and their inputs & outputs are described in detail below. Also see the brief connector summary.

Please note that this document is currently being updated. Much of the technical information for the 2C0B is the same as the original 2C0 described here. We hope to have this document updated by 27th June 2010.
