Introducing the new RACE 8 Channel CAN bus wideband oxygen sensor system designed and manufactured by OberBuilt Inc. This system makes installing eight wideband oxygen sensors for individual cylinder monitoring a breeze. RACE programs the unit and terminates the CAN bus cable so the unit is plug and play with Holley EFI systems. The indivdual AFR readings are fed into your Holley EFI ECU allowing you to datalog them, use them in advanced tables, or other powerful uses. The unit supports either Walker/NTK part number 250-25001 (has 1 foot pigtail length) or Bosch 4.9 sensors (PN 17025 is recommended with it’s 3 foot length). The unit includes the wide band controller, fully terminated 02 sensor harnesses, and terminated CAN bus/switched power harness. The 02 harness total length is 6 foot in all kits (harness plus sensor). The unit can output AFR in either Lambda or AFR units. During checkout, you can choose which AFR units you would like programmed : for Gas (stoichiometric is 14.7:1), E85 (stoichiometric is 9.7:1) , Methanol (stoichiometric is 6.4:1), or lambda.
Wide band 02 sensors are to be purchased seperately. Bosch sensors retail around $65 and the Walker sensor is around $80 from Rock Auto and other sources.
If you change the 02 sensor type, AFR units, or other items in the future, the unit can be re-programmed with the programming software via WiFi.
