    Default Spark Advance vs. Gear or MPH

    I have a 99 Corvette with Custom OS 02020005. My problem is that I get some knock when in boost but typically only in 5th gear or higher. Is there a way to pull more timing out based upon what Gear i am in or based upon MPH? Maybe a clever way to use the N2O timing table ... such as some sort of switch that could indicate I'm in 5th or 6th and use that to trigger the N20 timing to pull out more advance?

    Appreciate any clever insights you might have!

    Thanks,
    Bobby

    No,

    I have asked for this, but in the end it's not that needed.

    you could set up the nitrous/valet switch to do it.....Im thinking of even manually flipping the switch at the track in 3rd gear

    That would be really cumbersome and not a seamless solution.

    IAT no.. the best solution would be coolant temp.
