i think these afr values wrong because values not stable i attach videos.
im sure the pinouts(ecumasterusa site) and wirings.
What was the error?
Thanks for comments, sorry for my bad english.:(

Edit 1 : i installed base map from ecumasterusa website these values for stock naturally aspirated miata (98-00).sensor installed the stock lambda sensor on manifold.
