Running bluetops and armstrong 93 chip or delco chip at 35 psi
Values before catalytic convertor:
At 40 km/h
HC limit 106 actual 151
CO limit 0.59 actual 1.27
At idle
HC limit 300 actual 208
CO limit 1.5 actual 1.71
NOx limit 1164 actual 435
Values after catalytic convertor
At 40 km/h
HC 277
CO 9.91
At idle
HC 288
CO 4.34
Nox 290
Why are the values increasing with the catalytic convertor? I have tried the factory cat and a fairly new aftermarket cat. I have also tried switching out the 02 sensors twice. Both brand new ACs, but I believe they are not getting over 800 mv.
Need help!
