[QUOTE="Jon, post: 444920, member: 5219"] I'm the author of the BJM article you followed. I did it on my '07 FRJ after the new ECU was installed, so I can attest to the fact that it works. If you didn't get the wire swap correct, or if the wire was not seated properly in the holder, the CO adjustment will not work. The PCIII is a great addition, but for those who don't want to spend the money, the BJM and CO adjustment are definitely worth doing. These foour mods have greatly improved throttle response on my bike: 1. Balance the throttle bodies. 2. Take the slack out of the throttle cables. 3. Unwind the throttle return spring one turn. 4. Do the BJM and adjust the CO on each cylinder +7. Jon [/QUOTE]
