How does the 4age AFM system work?
Guys, I'd like to know a bit about our AFM unit and how it works.

Also what impact does the screw adjustment have on the overall vehicle running?

Thanks,
Heshan.

This was very helpful..

Does anyone know the standard setting in AFM? Right now I'm having a high CO rating in my exhaust and getting very risky with my emissions test.. Want to know whether its got anything to do with my AFM..

Will be doing a tune up as well..

do you have a CAT or not?

not entirely sure anymore as I haven't had a CAT for 5+ years and the brain isn't what it used to be. If I remember correctly, if only CO is out then it's most likely the CAT - was the car properly warmed up? a hot CAT works way better than a cold one.

Yes it was.. It was in running temp for about 15 mins..

So a tune up isn't exactly what's going to resolve this you think?

if you say running temp for 15min - do you mean just idling? if yes that's not going to cut it with an old cat. go for a spirited drive for 30min and then straight for a measurement and see if anything changed.

I did a spirited drive for 15 mins.. Sad

Probably I should change the cat to a newer one anyway..

I assume your timing is right, TPS set correctly and no leaks in air supply or exhaust... also no fault codes from the ECU. If you have a CAT you also have a lambda sensor which could be out of calibration due to wear or covered in residues
