    Camshaft Ramp Rate

    Has anyone experimented with tweaking the positive or negative cam ramp rate?

    Seems like this could potentially be another factor that impacts throttle response(?). I'm thinking about increasing them by 5-10% to see what happens.

    Use a faster polling rate in the scanner and see if you can tell a difference. I think it would be hard to spot even on a data log.

    That's an idea, although I would need to devise a repeatable test for a proper before-after comparison. I'll probably just increase all the values by 10% and see if I can feel any noticeable difference. Not expecting much, though.

    I've experimented. No real difference. The increase in rate is minutus and can't truly be "felt" on the butt dyno. You're better off tweaking the spark VCT tables for that
