    LT4 Driver Demand settings way out of wack

    I watched this video on YouTube (https://www.youtube.com/watch?v=bCbi-boBCVo) about driver demand and torque settings for a Gen V and in listening to what he says and compared to what my settings are, mine are much higher than expected.

    Here is a screenshot of my driver demand settings.

    I have also attached my latest tune, which in my opinion it's completely screwed up. I do not have a copy of the original tune that came with the engine and I don't want to load a tune from a 2017 Z06 because many of the systems on that are deleted in my setup because they do not exist.

    Please let me know your thoughts.

    Your dd table is not in lb ft. I'm not sure what unit it is in or if it is a unit. I'm not sure why but some software versions do it like this whereas others are the more typical rpm vs accel

    Is your car a manual or an automatic? The DD tables are vastly different between the two. Also depending on the model and year, the values may reference MPH/KPH or they may reference RPM.

    Don't ever copy a Driver Deman table from any vehicle into your file. Always start from your stock file. Don't go crazy adjusting everything below WOT.
