What is the proper setting for wb lamda delay in mlv? How can I determine this value from the log-files in mlv?

I am using the default setting , I did wonder if changing it would be better but it seems to work ok as set.

If you rapidly open or shut the throttle then you should see a large jump in AFR a few records after the throttle movement in the log file. Count the lag in several places in the log file and take the average. I am currently using 4 records, but it will vary with the distance from the head to the lambda sensor and with the exhaust gas speed.
