As said above ... good idea ... wouldn't hurt a thing
The stored CL data in the pcm is obviously based upon the old O2's
Sooner or Later ..........
that will be written over by the data from the new O2's
Now ... if you are doing some tuning at this time ... a pcm reset will get
you started on gathering complete data from the new O2's quicker.
You would certainly have skewed data if you did a dlog right after
installing the new O2's cause the adaptive would not have had
enough time to do two things.
1) see a new value for each and every condition
2) make however many steps are necessary to become stable
at all those different conditions
