Title: Fuel Trims Post by: vdubnation on July 18, 2016, 01:38:37 PM Why does every car i ve seen lately have a difference in partial banks usually 2%+- between banks.
This is not just 1 car over 10 cars tried swapping injectors , mafs , leak testing , its a pattern . All of them are Stage 3 S4s. Title: Re: Fuel Trims Post by: Jim_Coupe on July 18, 2016, 02:29:28 PM I have this on my 3.2VR6T and my non scientific conclusion is that there is a small difference in the banks. If you add all the small things as air leaks+dirty sensor+injector diff+oil leaking from valves and so on you get a difference.
