I know that I can change the speedo ration with a SCT tuner but I have a wifi obd2 adapter that I was hoping to be able to change with.
Do I have to have a tuner or can I just issue a few commands over OBD2 to change the ratio? Right now that is all I am looking to change so $300-$400 is a bit much.
