I bought a jb4 second hand as well and ran into the same thing. You just contact Terry at Burger Tuning and let him know you bought a used jb4 and it is locked out and he will get it working. Might just need your vin on your car iirc or something small.Did you happen to unlock the JB4? I’m having issues connecting to it. Would you also know what map you left it in?
