So i bought a EHS controller, along with the air box lid and a full FMF exhaust. I installed everything and then tried to set the controller and the minus button appears like it does the same function as the mode button. I can raise the numbers in each mode but I cannot lower them. It appears like the box is just a POS and needs to get returned for a replacement, but anybody know if there could be another cause? I have checked my ground several times over it seems to be good and the other wiring is pretty self explanatory.
