english is not my native language, so i may butcher it a little

I have 2010 SMT and today i found out why speedometer is showing about 1/8 of actual speed - i have dashboard from abs version :/ One of previous owners replaced it. Becouse reasons, i suppose.
Is there a way to make my current dash to work correctly? Or my only choice is to buy dash from 690 or 990 without abs?
