Im between 1.7 and 1.9ms pw at idle

I can confirm, idle control takes forever to tune, a ms newbie will tune the whole fuel map before an expert tuner will tune the idle.

My only idle control success storie finished with a 120R, 10 watts, resistor in line with the ISC signal. At the same time, it quiet down the "bwwwwwwwwwwwwwwaaaaaaaaaaaaaa" that was making the ISC each time it was in function.

Just installed a Vishnu dual feed rail and idle is smoother overall. I will pull some fuel from idle and see if the roughness comes back as bad.
