C20XE air flow meter adjustment guide

[rizaan.jappie]

Is there a guide to adjust the COs for the C20xe via the air flow meter?

im not too sure this is adjustable.

i think you could only adjust the ones that didnt have a cat. SEH/SER engines and 20XE engines.

Hi thanks, I think the COs for the C20xe are adjusted with the Potentiometer.

I'm not sure either tbh, I know the early dizzy cars have a screw, but I've never adjusted it!

According to the Bosch operating criteria manual i have for the C20XE, if you have a lambda sensor, altering the screw on the air flow meter does nothing unfortunately.

As above only early engines non cat could be adjusted all later ones no adjustment if set up for lamda and cat
