    Anyone good with nistune?

    Car went for mapping last week but mapper couldn't get after crank enrichment high and it is running rich all the time.

    Cruising afr is around 11
    Idle between 10 & 11
    Full boost 10-10.5

    Obviously other than on boost this is not right.*

    The car also has a stutter at approx 3k revs.

    Any pointers on what I can do myself to resolve this?

    Spec is-
    Garrett 2871r turbo*
    Greddy profec spec 2 at 1.3bar
    660cc injectors*
    Fully forged
    Tomei poncams (oem setting)
    Z32 maf*

    I also noticed when looking on nistune at the file that it has the ecu code as a 39f05 which is a lambda ecu whereas the actual car is a non lambda model.

    I have attached the bin file of the map

    Nistune board should always be matched to ecu code, had my tuner say this to me when he sorted my base image

    you can remove the closed loop function by the cell value , i believe its obvious when viewing in raw values

    there must be something terribly wrong when running those afr's

    Would closed loop be the higher numbers? In a pale blue.

    yes i believe so , its something like subtracting 128 from te value to removed the closed loop,

    verify if the filtered value stays the same after , i'm not 100% sure of that , its been a while

    There is an option in Nistune to disable the closed loop function, but closed loop is only enabled until around 3500rpm. After that, it's all open loop. It seems there's still something wrong with your map.

    Be very careful overfueling, all that fuel is ending up in your sump and thinning your oil. Guess what happens next... knock knock?

    Do you have a licensed version of Nistune to be able to make changes to your calibration? If not, i can't see how you're making any changes at all...

    Yes I have the license etc.

    Tbh cruising I'm rarely over 3.5k so it's a starting point!

    I will open up nistune software and have a look thank you
