I'm in the process of doing a smog legal swap and even though I'm not in California the emissions system from the donor vehicle was a California emission vehicle. When I changed OS's to a different different vehicle (I'm using a 4L80E) the calibration file didn't have the last 8 of the vin (they were set as all 0's) and I cannot verify which type of emissions the tune file was equipped with. I'd prefer to not buy the more expensive California catalytic converter unless I have to. Is there any way to tell via the tune file which emissions the vehicle had?

Due to how the vehicle is checked for the initial smog inspections the O2's cannot be switched off, so that is not an option...
