Current theory is what I will refer to as "pre-limp" mode where the car cuts power based on coolant, oil, or trans temp. I need to log torque limit parameters to figure out which one. My past track day I was definitely in the coolant temp zone for this (maxed at 248F, pre-limp is 242-255F). Oil was 262F (pre-limp is 300-314F). Only one I don't know is trans but it got to 255F and my tuner suspects it is the culprit. Thinking about getting a secondary trans cooler as the trans would be drawing up the coolant temp as well.
