Mixture screw tuning???
« on: 13 July 2011, 09:14 »
Hi, thought I read a thread on here somewhere that you can
Change the mixture screw setting to get better performance!
Is this true? I have got mk2 golf gti 8v digi, I have also drilled
The airbox does mixture need to be adjusted for this?
Any help much appreciated as new to this!!

Better to leave alone tbh.  :smiley:

Also it is controlled by the ecu on a digi.

Because you have digi, your airflow sensor detects how much air is being drawn in and will increase the fuel to match, to a certain extent anyway.  If you drilling your air box has increased airflow, the ecu will match the fuel.
