I had it blinking once and called UPREV and they emailed a different ROM, which solved the problem. But I have an 04 with the smaller memory ECU.
Started 6 moths b4 uprev. Cipher says its a brake switch, so does that mean its going bad? I cleared the code. By the way tb, what times do you run? Hows the drone with that 24"?So it was preexistent? Nothing to do with UpRev?
