closed/open loop questions

Dataloging a drive around town today in closed loop I noticed that when I take my foot off the accelerator to shift or slow down, the car would go into "open-driving". Decelerating, with a very light throttle produces a cycle between "open-driving" and "open-cold", and the car bucks and jerks.

Is the car supposed to go into "open-driving" when decelerating in closed loop?

My next question is, are the lambda correction tables (shift-F5) accurate when running in closed loop?

Last question, under part throttle like 1/2 3/4 throttle acceleration, should my target lambda be 14.7, 13.2, or somewhere in-between?

Very much enjoying my K-pro. So far, I have tuned my car to almost 3/10ths and 2 mph. faster in the 1/4 mile.

Open is normal upon decel. The tables that you describe (lambda correction) are not used by the ECU - they are only for tuning purposes.
