I installed aem uego to my car. i wired the output to aem ems.(ita 1year old. it was in my other car) the output voltage much different like aem manual says. the aem gauge shows 13,8 afr, the ems shows 14,7.
it is possible to have output failure?

 

You have to play around with the O2 Gain so that the UEGO (with sensor UNPLUGGED) sends 2.32V to the EMS. Just screw with the GAIN til O2#1 Volts reads 2.32V. Also, be sure to check that the correct wideband is marked in the O2 Sensor Wizard.
