OK potential customer here.
I have a 2001 Trans Am and I have long tube headers installed. I am getting the DTC's regarding the rear O2 sensors. Only thing is I actually have them installed and they are working. Only problem is that they don't warm up fast enough. I need to get the car inspected for me to drive it in my state but the fact that the car is throwing codes is what is causing the car to fail inspection. Can I change the DTC parameters using the VCM software so that the codes are not reported to the PCM. If the codes are put into history the thing will not pass. I really don't want to purchase this software yet if it won't fix the problem I am having.
