Emissions Testing - Valet or Full Mode - ZR-1 Net Registry Forums

RichieDMD · 09-03-2021

So, my 1995 ZR-1 should be arriving today and I've got to get it emissions tested before I can register it. I know that the car recently passed the California smog test...so it should be no problem. I'll ask the former owner what mode he had it in.

But for general knowledge, is one mode better than the other for keeping emissions low. Oregon requires the Hydrocarbons to be lower than 220ppm and the Carbon Monoxide to be lower than 1.0%.

Also, if valet mode is preferred...can I switch from one mode to the other while the car is running or does the car need to be shut off to switch it?
