I am going to be tuning my VAFC on the dyno tomorrow night. I have a question. Is tuning narrow throttle beneficial at all? I wouldn't know how to do it. Can someone provide me some insight on this matter? thanks for the help.

You can't possibly tell me no one has tuned narrow throttle on this whole board. What gives??

 

At "narrow" throttle your ECU is running in closed loop mode, right? What do you want to tune then?
