    I'll bite. What in the world is rpm corrected against? I assume it must be a sensor or noise correction and not something like the pull of gravity affecting the crankshaft? LOL

    Wowsers. Yeah, screw VVE at this point. Just get a good MAF tune first with all the other wonky sh!t fixed. If people get paid for this nonsense, I should quit my day job. LOL

    Just bump up the idle adaptive torques to something in the 20's or 30's. It will do what you're looking for, though I think it sounds like crap. You can google all kinds of youtube folks doing this...

    I'm not 100% sure of the exact purpose of the "bias," but I know some people have lowered all the "max" values to limit intervention, and say it is better than just disabling. Try values of 30lb-ft...

    Bingo. You want to have some hysteresis or dead band there so it's not flipping back and forth as you approach and are around that RPM. Similar things in the rest of the tune, such as rev limits,...

    Have you done a "re-sync interface" in the software? Sometimes that fixes silly issues with MPVI's. Might work for the RTD's too

    And to completely tie a bow on it, the "re-enable" is simply a hysteresis so the change point has some gap, like many other parameters in GM tunes.

    I can tell you with certainty that 17 and 18 ZL1's have positive values as high as 19 degrees in those rows.

    Greg's right. Copy the top three rows of the minimum spark table from a 2017 or 2018 ZL1, and it significantly reduce the pop-bang. They intentionally introduced more burble in '19, and I think...
  17. Throttle rate, application and decay (Camaro/Corvette)

    Has anyone ever found a parameter/table for throttle rate application, both increasing and decreasing, that applies to the different driver demand maps?

    I did this for a week for the heck of it a few years ago. It was actually pretty cool. Not my cup of tea, but just enjoy playing with stuff.

    My 14 ZL1 did it at 1600 and 2600, too. But only if the MAF was failed. Once it was blended again, it was fine. In short- I ignored the spikes and all was fine once running a blended tune again. ...

    75 mph is pretty low, but I'd make sure the limiter is not there to combat a low natural frequency of the driveshaft. See also: Exploding Silverados.
