Every ECU automatically corrects for ambient temperature and pressure. In any bike or car.I wonder how much of it has to do with atmospheric conditions. For example, I live at sea level in temperature that runs from high 50s to mid 80s typically. My bike had zero issues with the stock exhaust including cold start etcetera. I only tuned it after replacing the cat and muffler. I see people in 4 season areas talking about keeping it running when cold or choppy throttle response.
