Wheel Deadzone issue

[Crispyduckling]

Hi all,
I have a horrible deadzone issue with my Ffb wheel, there is a massive deadzone where i turn the wheel about 30 degrees and nothing is happening
it makes playing any racing unplayable.
I have my wheel setup fine in other emulators like Model2, Super Model and Teknoparrot with no issues.
now i have searched and found some vidoes on Youtube which show me how to change the deadzone in the mame menu to 0.1 or 0.0..
i have done this and saved it but it has 0 effect ive changed saturation to 1 and still the wheel has the same issue.
im lost as to how i can get the wheel to work correctly?
i would apprieciate any tips or has anyone else ran into this
Cheers
