Hey if I dont have the smog pump on for the test and the cats are still a little warm from the drive will I pass emissions.... I know the smog pump helps with cold start emissions... if not is there a temporary program I can run, I have tunercat and datamaster, that will allow me to?

The AIR pump only turns on for a few minutes to help heat up the cat. That's the only time though. So if your cat is already warm, you should be fine.

Yeah I wasnt sure if there was a cold start emissions test or whatnot, heard somewhere there was but I talked to a guy today and he said he lets them warm up first so thanks.
