+- on all units shipped to date with INA180A4IDBVT, the max current the current
+  sensor can read and stay within 3.3V ADC input range is 16.5A.  The intent
+  was for the full scale range to be 150A, but that would require the A1 part
+  not the A4 part!  We may be over-voltaging that ADC input on existing 
+  product in the field during drag-race conditions?
+
+  Let's just eliminate the current sensor entirely for future production runs
