    Fuel idle trim/IACV - Global inj.correction

    Hi all,
    I loaded new maps with Tuneecu to my Tornado 900RS and TREK Amazonas and I need advice for setting values of Fuel Idle Trim and IACV for Tornado and Fuel idle trim - Global inj.correction. I mean some initial values from which I can start final tune.

    The idle fuel trim and IAVC adjust values are highly dependant on how the throttle bodies have been set up, giving values that will work well for every bikes is not possible. The idle fuel trim should be set using an exhaust gas analyser, and the IACV trim should be set to move the stepper into the desired 30-35 step position with the engine fully warmed up. These two controls affect each other so you have to adjust one then go back to the other multiple times.
