Nice meter but needs changes needed to read accurate  regulate voltage into
whetstone bridge then put a constant velocity pump on it . Remember to not go way
lean it will invert and show rich.  Nice meter just a bit slower than new wide band
o2 meters but no sensor to change ever . Tune race car with one for years.
