Default AFR Table SERT

May be a dumb question but looking at the AFR Table for the SERT what is considered ranges for idle, cruise, and WOT. How does the AFR table convert to percentages of throttle?
Thanks

It does not convert to throttle angle. The MAP sensor measures the pressure of the air in the intake manifold. In general the higher the number the more load is on the engine. So if your traveling up hill, down hill or on level ground the MAP reading will change while the throttle angle remains the same.

Higher throttle positions are higher map pressures. Map pressure is mainly a function of throttle position and rpms with throttle position being the biggest factor. Higher rpms at a given throttle position is generally lower map pressures. You are dealing with a mechanical system though so things don't change instantly. As a result you can see some big differances between steady cruise speeds and rapid acceleration.

Largely it doesn't much matter. You're going to need to play around some and do road tests to see what differance changes made on a practical basis. A professional tuner with a dyno takes 4-5 hours to tune a bike. You aren't tuning to that level but still you have to figure 30-40 hours. It's a hobby.
