It doesn't look like it should be triggering at the coolant temps your log is showing but try changing from coolant based to normal.
I literally just made that same connection too and was coming back to say so lol but you beat me to it! You're the Spartman. :P I'm ganna try that out and if it fixes it, as messed up as that would be, I'm not even going to care because you can't ask for an easier fix with no major downside!

That has to be it. The correlation is so strong. Thank you for reading and looking through everything so closely for me to solve this. I Will report back if it works lol Don't got to ask me twice, I'm about to throw on shoes now and see if she will WOT for the first time since forever haha

Turned out to be the coolant temp based rev limiter. It's fixed now! Thank you to everyone that tried to help. Appreciate it!!!!

For some reason it just does that. No idea why. FYI if you're ever hitting a rev limit based on your throttle input, check if you have coolant temp based rev limiter on and just turn that sucker off =/ Or maybe just set the override rev limit to the same as your regular hard limit and that might allow you to fix the problem and still keep the CLT rev limit feature.

.. I wonder if efianalytics knows about this bug. o.0; I do have a clear memory of reading something on another forum a while back that someone else experienced a bug related to the CLT rev limiter feature. Though not able to remember if it was the exact problem I have.
