    The following two options are available for the Holley Commander 950 TBI system.....


    Wideband O2 sensors:



    http://www.holley.com/534-188.asp

    $773.95 @ Summit Racing


    and

    http://www.holley.com/534-197.asp

    $586.69 @ Summit Racing



    The cheaper one uses an "Bosch" sensor....the more expensive one uses a "NTK" sensor. I'm not sure what else is different with the two kits...???

    Anyone know what the differences are????

    Search on DIY Wideband O2. There are a lot of opinions out there on both sensors.

    Important clarification:

    NTK is not a brand.....but a "type" of 02 sensor, correct??? :dunno:




    The Holley literature doesn't make it easy to understand.

    Kit 534-188 ($773) has a photo showing software, manual, sensor and harness...
    • Pro Software - 64 cell programmable A/F matrix
    • NTK Wideband Sensor
    Kit 534-197 ($586) has a photo showing sensor and harness only...
    • Comes with a Bosch LSU4 sensor
    • No Software is included, but the "Pro Software" is included in all of their current TBI systems anyway...
    So... it sounds like the cheaper system doesn't make me buy software that I already will own for free (once I buy the base Commander 950 TBI setup) but will not have the NTK-style O2 sensor. The question is: how much can that sensor be purchased for?

    The two kits are almost $190 apart in price, so if the NTK 02 is cheaper than that.....the cheaper kit can be made to do the same thing as the more expensive kit, without the redundancy of buying software I will already own???

    The 534-188 says It will plug directly into all Commander 950 harness and accurately measure any air/fuel ration between 10:1 and 20:1.

    The 534-197 says It will plug directly into any Commander 950 harness and accurately measure any air/fuel ratio between 10:1 and 18:1

    you also can download their "pro software" right from holleys site for free. they even say that on the 534-197 page. so i don't think thats a selling point.

    Maybe one is heated, and the other is not. I would consider heated a must. If it doesn't measure in real-time and make adjustments accordingly, and is only a supplemental tuning aid, then you'd be better off looking at a stand-alone setup for a couple of hundred dollars.

    Even the harness for the narrow band sensor on my setup is heated, so I don't think that there would be a difference there.
