Hey guys i recently bought jb4 from another f10 driver just got it installed,
Now my issue is that my check engine light keeps coming back on, orginally the issue was that i didnt have the obd2 cable so it stayed as disabled now i fot the obd2 cable installed shop cleared cel and after 40-50 miles back again now i know its the issue bc i took it to autozone and code came back as "catalytic converter below threshold" since i have catless downpipes the jb4 pretty much is still inactive. Now they are telling me i need the bluetooth connect kit in order to even activate the jb4....is this true or are they just throwing add ons at me for no reason
