    M50tuB25 to rich AFR

    Hello guy's

    Im kinda new here, have been reading alot of posts before posting anything.

    But I don't seem to get my AFR right.

    My setup:
    Engine: M50tub25 8.8-1 CR, Stock internals
    Turbo: GT3582
    Wastegate: Tial knockoff 44mm
    Injectors: 440cc bosch (0280155968)
    ECU: KDFI V1.4

    The car idle's at around 600 rpm and my AFR is at 9.

    Here is my projectfile and some datalogs while the car was running.

    Cant figure out why it is running so rich. Checked all my settings for four times now.

    Hope someone can help me out.

    And since im new here, this is the car where it is all about:

    So, I managed to get the AFR right today. Missed one settings and cleaned the wideband. Now everything seems fine.
