Complete newbie here in tuning. Car is a 2009 C6 base. Lately I've been having some cat problems, basically p0420 and other "cat efficiency low" codes and engine has been running rich. Using HP Tuners, I set the COT to disabled and all the DTCs to "No Error reported". However, I cant seem to find the "Catalyst Test" and "Post O2 Test" in "General" tab in "Engine Diag" window. All I see there are oil pressure stuff, like what's in the pic. Does anyone know what's going on here? Thanks for helping out guys!
