Holley Wideband Oxygen Sensor Upgrade
Product images may differ from actual product appearance.
The wideband oxygen sensor is the ultimate addition to any Commander 950 EFI system. It plugs directly into all Commander 950 harnesses to accurately measure air/fuel ratio between 10:1 and 20:1, allowing the engine tuner to read air/fuel ratio in real time for extremely accurate tuning. The Pro software included with the upgrade features a 64 cell target air/fuel ratio matrix that enables the tuner to program the ECU at any target air/fuel ratio for best engine power and economy. All engines will benefit from this upgrade, and it is a virtual must-have for forced induction engines.
