Wonderin how my emmisions fare up against the average and other cars.

I got
Fast idle
Engine speed:2676(2500/3000)
CO 0.14% (max 0.20%)
HC 25PPM (max200)
Lambda 1.03(0.97/1.03)


Natural idle
Engine speed:884rpm (550/1100)
CO 0.04% (max 0.30%)

That should be Max 0.30% mate

Your readings are perfectly normal mate, not 100% but totally acceptable

Reckon they are the way they are cos of mods??
Strate thru!!!!

You cannot have a straight through exhaust and achieve these readings

You car Must Have a catalyst fitted to have the above readings.

I dont mean straight thru all the way.Its cat-back,used to be de-catted but i put it back on for da MOT and its stayin on as it sounds better,better fuel economy and the performance difference is neglegable
