Built the El Cheapo, I purchased the upgrade 10 turn pot and flow resistrictor with cap. After leaving the o2 sensor (Teledyne R-17) out all day, I can zero (20.9) the sensor. When getting a reading from regular air in a tank I get a reading of .5 higher (21.4), when taking a reading of a tank with 31% I get 32.4%, I checked it with my neighbors analyzer and his reads 31.2%. When reading a tank that was filled at the shop 33.4%, I read 34.4% neighbors reads 33.6%.
Any ideas on what is possibly wrong? I checked all connectons so far.
Thanks-
