According to the service manual the Adaptive Fuel Values are learned every time the system is in closed loop mode and the values are applied during open loop mode. So does the reset wipe out all the data causing the learning process to start over? It kind of sounds like unless some changes have been made to the intake, exhaust, or something it wouldn't accomplish much. Or does an adjustment like a TPS reset change things enough to warrant a AFV reset? | ||

There's no reason to "reset" the AFV (adaptive fuel value)because it will only reset itself once you start riding again. The TPS (throttle position sensor)is reset to synchronize the TPS with the ECM. | ||

Makes sense to me. I'm curious how the ECU keeps the AFV data. Does it do some averaging or is it a first in, first out kind of thing. I read in another thread that the guy had reset the AFV values and the bike really ran like crap until it had a chance to relearn. If there's not much to be gained I'd just as soon avoid that. | ||

In closed loop (learning mode) the ECM monitors the O2 sensor and changes the AFV to maintain best mixture. The current AFV can be read with diagnostic software. |
