Bosch LSU4.9 Wideband Sensor
This is the follow-on to the incredibly popular Bosch LSU4.2 sensor that made widebands affordable to every enthusiast. These sensors are slightly faster reacting, and last longer. The do require different connectors, and require that your controller supports these sensors. Our VEMS ECUs with the 1.2.30 and newer firmware supports these sensors. If you have an older ECU, a pull-up resistor to 5V is needed on the nernst wire, new ECUs as of 2016 have this internally from the factory.
