There is a lag...true. However your computer, EVO, DSM, Nissan, and yes even Hon-DUH, use long term fuel trims to compensate. Granted these come from short term fuel trims, which are a function of your front o2 sensor input over time. Using the narrowband sim may not be 100% accurate, but these value are within 10% in my experience
