Scott,

Yes you can use the O2 sensor to set the Co. According to the Bosch Fuel
Injection book by Probst, the correlation between O2 and CO% is very
similar.  I.e. .5 volts on the O2 is approx. 5% CO. For a complete
instruction on setting the basic fuel injection search the Archives

Subject: setting co at afm question

im just wondering if there is a way to set the co at
the afm without an exaust analyzer. i guess im
wondering how proformance may suffer from
mis-adjusted co....if not- how much is an analyzer? or
would it just be less expensive to take it in and have
the shop do it? possibly getting the upgraded ecu for
the 1.9L and would have to adjust the afm...thanks for
any help.
