VAG-COM: Adjust Fuel Injection Amount

'Yesterday, I tried to slightly increase my initial fuel quantity and injection amount using VAG-COM, but nothing happened when I changed the standard value of 32768. The same thing happened with the idle speed. It seems that you can only enter specific values.'
Can someone tell me which one?

The engine is either a 110 hp AHF or an 115 hp PD AJM.

I couldn't find anything useful using the search function...

Hello,

You must first complete the login process (see error database).
If you want to increase the fuel injection amount, you must decrease the value.
Try making changes in increments of 10.

I've completed the login, but even changing the values in increments of 10 isn't working. Out of approximately 8 million values I've entered so far, only about two have been accepted... However, the displayed initial values in the measurement blocks remain the same.

Hello,

What values are accepted?
