idle problem with mx1 cam

my setting is like this . it seems does not work at the normal idle.it is still in 680~780.it is rough.
but it work when is moving the steering wheel,AC on or in gear.i can see the idle jump to what i set.
i have set 898's to 945's
i have checked all the place that can cause VAC leak of the intake manifold and the throttle gasket.everything is ok.there were no VAC leak.
any ideas?
thanks

Maybe change the lower values to either 898 or 945 as the lowest numbers. Possibly because they aren't the same it is causing a default value?

I also leave the upper part of the tables all the same when I make changes, when setting RPM I only raise the values below what I want for an idle RPM up to a higher value. That way the car behaves identical to stock as it warms up and just doesn't idle as low when it reaches full temp.

your power steering pump adds load to the engine when you turn the wheel. what you are seeing is a response to that load. Its only a problem is the extra load causes the car to stall.
