Hi everyone, I'm planning on doing some mod's to my new Concours and have some questions. My bike is an 09 Concours 14 ABS and I'm planning to add a K&N air filter and a Two Brothers VALE slip-on. After reading the posts about power commander and removing the butterflies vs. Guhl re-flash, I've decided to go the re-flash option, and that's where my questions start. I purchased a used ECU for my bike thinking that I would send it out for re-flash, that way I wouldn't be so paranoid about it getting lost or damaged in the mail and I could still ride my bike in the mean time. Then I read a post stating this "Furthermore, you need the KDS3 tool to replace the ECU because it has to be "registered" into the system, and the Kawasaki dealers are the only ones with the KDS3 tool." So now I'm wondering if the Dealer is going to give me heartburn if I try to have an extra ECU setup to work on my bike? Have any of you done this before? And then my other question is about the re-flash itself, I know it will open the butterflies sooner, but will it also be customized for my combo......air filter and pipe? I appreciate any info anyone can give. Thanks, Brian
