Hi,

I am a relatively new owner of an 89 sapphire 2wd.

I have just hit the CO emissions hurdle over here in italy. My revisioni ( mot ) guy is saying that the car is running at 10% CO when it should be running at 0%

Firstly I dont believe that a non cat should be at 0% , I am guessing standard would be 2-4%. What is the standard CO on these ?

Secondly, can anyone help me on how to adjust the CO just temporarily to get past this check ?

Cheers

Paul.

 

ecu in the panel in the passenger side dash , remove cover , and turn screw small amounts at a time , best to be done whilst emissions are being read i.e with the gas anilyser sampling , without the spec of your engine and whos map it has i it its almost impossible to say what it shoud run at , especially for european law

Thanks for the swift reply mark

Do I have to be careful how much I change it, can I break anything ?

 

yes its sensitive ,but will also adjust your fueling across the whole rev range so dont go winding it off to nothing m8 !!

 

Remember how much you turned it for the test and when you get outside the garage,turn it back up.
