Lambda Wideband Controller WB101

$USD 75.0

Overview

The WB101 combines an accurate, fast response wideband AFR (Air Fuel Ratio) controller with a Bosch LSU4.9/4.2 wideband oxygen sensor. The wideband controller works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. It includes two analog outputs 0-5V for interfacing with 3rd party devices, one CAN bus for interfacing with our aftermarket ECU or Megasquirt family ECUs and one USB for PC communication. The analog output is ideal for interfacing with aftermarket ECU’s and data loggers. The second output is ideal for stock narrowband oxygen sensor replacement where the simulated narrowband analog output is fed back into your ECU to make it operate as if the stock narrowband oxygen sensor is still installed while running the WB101 setup. All two outputs can be used simultaneously.
