hey, i have a used ecu that i bought from beaver honda in North carolina. i had it reflashed from the dealer to make it work with my car and sometimes the check engine light comes on and sometimes the battery light and key light flash every once in a while. i dont know what they did while reflashing it but do you guys have any idea what could be wrong? do i need to reflash it again? because i dont honestly know what they guy did while reflashing or changing the immobilizer. if you can help it would be great. thanks
