Standard RPM is around 1500 and timing is around 11° retarded. OFT adjust idle speed around 1100 and timing closer to 0°

Late models have actually around -19/-20 of advance timing, that's the software reachable limit for the ecu
Probably to get faster hot temp in exhaust when you crank on the car
Exhaust temp climbs really fast from ambient to more than 600 Celsius in like half a minute
