What bin and what mask do i use

[78monte]

Ok I've downloaded tunerpro and try to figure my way through it when I do find my right bin and mask witch way do they go into tuner pro

[steveo]

you load the xdf for your mask. that's the definition of the bin. then you load the bin, that's the calibration for your engine
