[list=1][*]Delay between the commanded AFR anf the WB AFR:
[indent]At throttle close, the air speed through the motor will slow down, so the WB signal will lag the rest of the engine parameters. The mount of lag is determined by the position of the sensor. Obviously, the further away from the motor it is, the more lag will be present in the log data. So this probably isn't a huge issue and I'd not be overly worried about it.
