What is the proper value of KRKTE for bosch green 440cc injectors? S4 have 4bar fuel pressure regulator... 440cc@3bar ~ 508cc@4bar ??? ...from s4 wiki - 34.125 / 508 = 0,067 Amiright? :) Any others maps need to change for first start on new injectors?

How to check that everything is ok now? Observe STFT & LTFT or use a wideband sensor? EGT is now lower on high gears... Title: Re: 2.7BiT KRKTE for 440cc injectors Post by: roman_tyk on July 27, 2020, 12:09:57 PM @idzioch did you successfully tune car using this krtkte and TVUB?

They are a great injector, but notoriously non linear. FKKVS will absolutely need some work, particularly in low rpm/pulse width areas.
