more tuning help!!!! please!!
hey guys ok
so my car has no cats, and my check engine light was coming on for the 02 sensors failing. i went into my hp tuning programming and cut the front 02 sensors off. that should take care of taht problem. the light came back on for a random misfire. i need this light and the dtcs cut off because i have to get my car inspected and it wont pass if that light is on. do i need to clear out all the codes throguh the hp tuner software, or will a gm tech be able to clear it at a chevy dealership.
any help would be great!!!
thanks

you disabled the FRONT O2 sensors?? for having no cat's, it's the REAR O2 sensors you need to disable the trouble codes for...
all of the O2 bank 1 sensor 2 and bank 2 sensor 2 codes...
not the front ones...
and the other codes you're probably getting are the 420 and 430 codes, because you have no cats on there... so those codes need to be disabled too...
as to how long you need to drive.. it can take up to 5-6 "drive cycles" for all the tests to run and complete...
but, if you disable all those codes so you don't get a CEL, then you won't pass anyway, because disabling those will not allow the ecm to run and complete those emissions readiness tests...
