Thread: C950 Tuning

  1. #1

    Default C950 Tuning

    I am trying to add more fuel using the Hardware Settings tab of the Commander Pro 950, and it will not let me put in a value lower than 10. Is it because it's greater than the 20% increase allowed with the wideband O2 sensor and my highest value at idle is greater than 20% higher? I would like to attach a picture of the screen I am modifying but can't figure out how.

    Thanks in advance for your help.

    Are you referring to the Target A/F Ratio table on the Oxygen Sensor screen (Hardware Settings)? If so, why would you want an air/fuel ratio richer than 10:1?

    Danny, I'm referring to the Target A/F Ratio on the Oxygen Sensor screen. If I could attach an image I could show you that the engine made it's most horsepower on a dyno with an A/F below 10. This engine has very large lift came with an M4SC blower.
    It's not the best combination of components for my application, but it is what I have at the moment.

    10:1 AFR is the lowest value the C950 software accepts.
