Sorry for the late reply but its been a busy time for me so have not even looked at my car so about a week.
Just popped out to see what I could do on the lap top ... first the screen in not exactly the same as the manual .
But I did a few things first I reset the system than ichanged the rpm reference act-min to 600rpm (car idles around 1000rpm) and good news it has solved the idle stepper problem
I did not set any min or max positions on the stepper just yet wanted to see where it was first .
Next I enabled the act-max increase in acceleration not to sure how to set this just thought it might cure the sputter on acceleration.
So I turn on the gas sat at 2500rpm for three minute and the stepper sat in the midle and the lambda went back and forth so that was good .
Car is idling rich still and the stepper does not seem to move to correct it as I thought it might ..
Car reved up fine but took it for a drive and it sputtered on slow acceleration but once this has cleared it drove fine and lambda shifted back and forth as it should ...
Just wondering if I need to increase the act-max increase in acceleration from 5 steps to more?
So it was a good start just need to get my head around all the setting and try get the lambda to swing on idle or im going to have to wire the bilt in lambd emulator up because its relly messing up the petrol ecu on the car.
Any one got any advice no matter how silly it might seem .
