got a light for po430 after header install
is there anything in hpt that will let me change the rear 02 parameters rather than turning them off.

thanx

 

no just disable the p0420 and p0430 codes

 

The rear o2's don't do anything but monitor the condition of the cats anyway.

 

no feed back to tune for sure??
i don't know but it would make sense that rear o2's would provide info to pcm for fueling
lean -rich.
if for sure, i'll turn them off

 

rear o2 sensors are ONLY for catalyst monitoring. the front o2 sensors are for fuel control. my rear o2 sensors are zip tied to my crossmember to pass the heater ckt test. i assure you they do nothing for fuel control.

 

^^^^^

that is the best way to understand what you are learning.
