Injection quantity -IQ
Creio que é a quantidade de combustível injectada....mas pormenores técnicos tb n domino...
Só sei que a baixei de 4 para 2.2 e de facto o carro consome bastante menos...por estranho que pareça parece puxar mais...
Aqui fica este pequeno how to:
A VW specific scan tool such as VAG-COM is required for this procedure. With the engine warmed up and running at idle in neutral with all major accessories such as air conditioning turned off, connect the scan tool cable and start the scan tool software. Select engine control module. "Login" using 12233 as the access code. Select "adaptation" and go to adaptation block 1. Note that the display shows a default adaptation value of 32768 and shows the amount of fuel being delivered in milligrams per stroke. (If it does not show this, you are either on the wrong screen, or you have an older ECU that differs slightly - see next paragraph.) The specification range for reported fuel delivery at idle is 2.2 to 9.0 mg/stroke and they normally run best between 3.0 and 5.0 mg/stroke (highly tuned non-stock engines may differ - you'll have to experiment in that case). If you see a number smaller than your desired range, enter an adaptation number that is slightly smaller (say 100 units smaller than where it is now) and "test", to see the effect. Adjust the adaptation number up or down as required to achieve a reported fuel injection quantity as close as possible to your target. It is only possible to adjust within a very limited range using this method but experience has found that it doesn't take much change to make a big effect in the shuddering. Once you get a proper setting, "save" it.
