Reply To: Dealer CAN adjust A.F.R. – LEAN February 13, 2019 at 4:01 am #3472 QwandreeModerator I am definitely a fan of the coober ecu, but bike still runs lean with one installed. At least mine does, though I do also have a link pipe installed. Very interested in what you learn about what the dealer tool can do for this (I am skeptical honestly). Keep us posted! And say say hi to the aomc folks for me. They seem like good dudes.
