I did read them but there is no datalog and no definitive description of the issue. "Acting up on the upshift" isn't descriptive and there is no datalog showing what you're asking. "Car goes into speed density almost immediately" doesn't make sense to me so I'm not sure what you mean there either.
What the Torque Model and the Coefficients do is already on the forum. If you want help, post the datalog with relevant the PID's and be more descriptive of what issues you're facing. No one is going to re write a novels worth of how things work when its been highly discussed already. I'm trying to guide you to a way to get help and learn along the way.
I'm not here to tell you to give up, but rather for you to post relevant info to get the help you're requesting. Once things are more clear for some of us that are willing to help make some changes for you or suggest what to do, you will probably learn a lot about the torque model.
You probably need to log the right PID's first. Here is a config file for a Gen6 Camaro to capture the useful channels for the issues you're facing. Feel free to use it...or not.
