How is throttle-by-wire programmed?
I have this theory based on driving modern cars and on what's possible with programming modern aftermarket ECU's that the throttle body doesn't go to 100% open when you press the throttle to floor.
My 2023 Tundra seems noticeably faster on part throttle than full throttle and my 2011 Cayenne didn't seem to have a direct correlation between throttle position and acceleration.
Is anyone here an expert on how the OEM programs TBW and care to enlighten us?
