Emission readings

Spooks

Hello all, been playing with my car again today and had it plugged into tech 2 yet again, mainly to reset fault code P0420, the guy was pretty helpful and spent some time with me on it, he reset it then said it all seems ok, he also put the 'sun' emissions tester in the exhaust to make sure the CAT was ok which he said it is and will pass the MOT as it is.
I tried remembereing the results on the screen and pretty sure they were as follows...
HC = 120 ish idle, 190 ish revved (not sure what rpm)
CO = 0.30 idle and 22 revved (i think)
CO2 = 12 - guestimate!
O2 = 0

Do these sound about right? what..

Daz

Hc's are fine.
co at idle fine and i presume u mean 0.222 at fast idle..

co2 forget and o2 forget,,,

no llambda reading there tho...

Limits for mot are,
fast idle 0.300 co
nat idle 0.500 co
hc 200
llambda 0.977-1.030

or if registered after sept o2

co at fast idle o.200
nat idle 0.300

If my memory serves me correctly lol
