    First, your laptop computer must be able to communicate with the ECU.
    Click on the About & Version tab (with the key-on) to find your current software & firmware versions.
    Your C950 software version must be compatible with your C950 firmware version:
    1.xx software = 1.xx firmware
    2.xx software = 2.xx firmware
    3.xx software = 3.xx firmware

    The firmware in your C950 ECU can only be updated by sending the ECU to Holley.
    The newest software & firmware will operate a narrowband or wideband O2 sensor.
    I highly suggest Holley's own 534-197 WBO2 sensor kit; it's "plug & play" with the C950 harness:

    You still don't understand. You must be able to communicate with the ECU to initially enter "Hardware Settings", and setup your Engine Parameters (engine, ignition, EFI type, etc.).

    I guess some old men like me just don't get it. Can you think of anyone up here in Washington state I could take this to? It's on a test stand and ready to go. I can deliver too.

    Where are you? I'm in Coeur d Alene, ID. If you're too far away, you could mail me the CPU and I could see if I can talk to it with my computer, as I know it works with mine. Have you tried the Comm port settings in the software?

    Sure I could mail to you. I don't have any software? I downloaded what Danny suggested, but I guess I need a tutorial, can't seem to understand this stuff?

    Shoot me a PM. Where are you located? I'd be happy to try and connect to it and see what you have. All I need is "the box."
