Thanks for your replies and information.
Looks like the system was not going into closed loop at all and the readings I was getting were while in open loop.
Working with a fellow that appears to know his stuff and in the process of "learning" along with very baby steps in making changes.
Advantage with the Tweecer is that I can keep the car on the road running a tune that I know works moderately well even if there are some problems while keeping the "play with" tune in a different switch position while it is in progress.
Still in the very early stages. I'll keep posting at things progress.
