Opel Maf help

[supafly001]

Hi guys,



is there anyone that can assist me in changing the scaling on my maf sensor housing, currently 70mm, Need it to be scaled to 80mm(vxr housing) for the intake pipe.



it is a Opel Astra G (z20let)
Bosch ME1.5.5


thanks a mill in advance.

If I post a file that does have the 80mm maf in it would it be easier to copy that to the first map I posted.
