These Holley wideband oxygen sensor upgrade kits are designed to plug directly into any Commander 950 harness and accurately measure any air/fuel ratio between 10:1 and 18:1. They will allow the engine tuner to read the air/fuel ratio in real time for extremely accurate tuning. The Holley wideband oxygen sensor upgrade kits are intended for the cost-conscious consumer who wants the tuneability of a wideband oxygen sensor, but cannot afford the high prices generally associated with a wideband oxygen sensor. The "PRO" C950 software and firmware are required. Commanders 950 ECUs manufactured in 2004 and later already have "PRO" firmware installed. If your ECU is older than 2003, these Holley wideband oxygen sensor upgrade kits include a certificate that allows the ECU to be returned to Holley for a free "PRO" firmware upgrade.
