    Default E78 Fuel Tables

    Hello Guys,


    I would like to calibrate the fuel on a 1.4T with E78 controller. I would like to take off some fuel on specific rpms and load.
    Is any fuel table which (e.g. injection correct factor) which could do the job?

    Thanks!

    we want at WOT from 5000 up to 6000 rpm because it is very heavy )AFR 10:1, but generally we are planning to change injectors and bigger turbo and they always need fine tuning, so we need to know how to do it

    OL fueling: see table B0148
    PE fueling: see table B3618

    both of those tables are already not adding much/any fuel...

    what do you see that makes you want to remove fuel...?


    You could mess with this injector correction table:
    B1219 injector correction by MAP

    Thanks for the quick reply. I think the B0148 is what i am looking for. It seems using this table i can add/remove fuel based on map and rpm. I will try that and give you some feedback.
    Is it possible to change the scalling of the table in case i want to do changes at higher boost?

    B0148 's axis ranges up to 180 kPa (i.e. 0.8 bar boost)... I would have to study the tune file to see if it's possible to scale on this table.
