Thanks Simon,
I had to give you a call on this to get you logging as you always come up with good results.
Since speaking to you I changed max idle area as I wrote in my post above. Lowering this prevents the idle "sticking" I will post a link soon of it idling with tables zeroed. It was sticking or hanging but no problems once tables were lowered. What is very interesting is the proportional and integral controls as reading the science behind these show proportional is a direct change and integral a sum of those changes but in this case it is ass about. Mine is idling at 7% and has no hunting at all with minimal timing correction, Now I have found correct airflow I will increase max idle area to standard setting and zero proportional control then using integral to correct minor changes.
Ringram would be good to see how your car goes with some idle tuning testing(save ur good tune lol) . Initially I had a few troubles with idle airflow and reducing proportional control helps a lot. Min idle airflow is nothing more than a minimum commanded TP% with max idle area being the above ceiling everything else in between is learnt and correct via airflow correction tables and spark control. Zeroing the tables and changing the other tables is how I was able to find correct airflow,
