Compensate Fuel MAP : Opening Throttle

Opening throttle is on every machines (R1 or R6) located around 10% (+ or –

4%). The most useful area is located on the dark rectangle on 4th page.

As described on data logging picture above, there is a time gap, or reaction

time between throttle opening and lambda start measurement. This time

depends of distance from cylinder head to lambda and also from sensor

reaction itself. It may also depends of data acquisition system measurement

frequency.

On Yamaha machine, we can evaluate this time gap around 0,2 seconds.

When technician wants to adjust 0 to 2% of throttle, he should keep in mind this

criteria.

On R6 machine, lambda value on opening area is not so critical as R1

motorbike. Usually, lambda target is :

12 to 12.5R1

12.5 to 12.7R6
