Hello,

Two weeks ago we had a thread on monitoring the composition of exhaust gas to
set the AFM.  The Bostig Engineering folks reccomended this wide band unit:
http://www.innovatemotorsports.com/products/lm1.php
and they can be rented from www.aircooled.net
I have looked into this gadget and realized that it measures the O2 content of
the exhaust gas and reports the air:fuel mixture ratio.  While this info is
cool, the Bentley does not tell us what the ideal ratio is supposed to be.
Bentley wants us to adjust the AFM based on the CO content of the exhaust gas
(not measured with the above unit).  So, does anyone have good data on what the
air:fuel ratio is supposed to be?  I have searched the web and found a couple of
CO monitors running about $180.  Anyone seen them cheaper than this?

Thanks,
Jake
