no AFR , LTFT , STFM after cat-delete Taurus 2013
hi HPTuners this is my first post
I have 2013 Taurus Limited 3.5L V6 naturally aspirated engine, I emptied may cats its legal in my country and tuned like below
Under Engine>General>O2 Sensors>Rear Config: Change to None.
Under Engine>General>O2 Sensors>FAOSC: Choose disable.
Under Engine>General>)O2 Sensors>02 Heaters>Heaters: Under Column Axis S2, change values from 1 to 0 in both Bank 1 and Bank 2.
cat temp control -》disable
Flange temp control -》disable
02 sens temp control -》disable
Engine diag:
O2 mil, O2 test -》disable
Catalyst mil, catalyst test -》disable
DTC:
P420 -》No Error Reported
P430 -》No Error Reported
after above changes my mileage decrease average 4 MPG I was thinking increase in mileage because old cats was semi-clogged
Today I checked with VCM scanner and my OL fuel status not ready and LTFT and STFT no data shown and there is no AFR what is the problem
btw CL O2 sensor temp : 350c unchanged
and Long Term Fuel Trims : enabled unchanged
