	650cc injectors 2002 Audi A4 Quattro 1.8t « on: January 19, 2017, 08:55:54 PM »

Hey guys I am having some problems with tuning these injectors I can get it to idle but I am running really rich. Does anyone have any suggestions? I have changed KRKTE TO .06 and have adjusted tvub. This car is returnless fuel system and I think that's what is causing it. Let me know thanks

How did you arrive at a krkte value of 0.06? I bet you are over 100cc's off....

For correct TVUB , check injectors spreadsheet.

What FPR do you have?

I don't have a FPR. It's located in my fuel filter

Your car is static 4 bar (not pressure on rise) returnless fueling. You may want to actually know what you are tuning before just making calibration changes
