Hi everyone
subaru sti link G4x plugin ecu version wrx11x
wideband aem 30-4100
wired to rear O2 an volt 7
present fuel is E85
I did already some test and see sensor is working
when I remove the sensor socket I see the an volt for 2.36
when I test the sensor full rich and lean also shows correct value
but when I start the car at idle couple minutes later lambda shows richer then afr gauge
calibration is also ok
many thanks inadvance
