We have a question hope anyone can help
I have the aem a/f ratio but not have the wide-band o2 sensor
So every I tuning my car I need to watch the aem ration lambda value for tune to 14.7
my question is can I watching the aem a/f value to 14.7 then compare ecu stock o2 sensor (the value about 17.x)and set my target lambda value to 17.x for turn my car on lambda percentage windows?

If you do not have a wideband sensor then you cannot accurately measure your AF ratio.
