[QUOTE="jstewart, post: 433727, member: 13630"] Does using the Techlusion require you disconnect the O2 sensor like the power commander does?? Another question--When you say CO settings of +32 do you mean the actual settings are +32 or that you added +32 to one of the original settings? I know you said earlier you decided to set all 4 CO settings at the same level due to the air box mods so I suspect you mean the actual settings on all 4 cylinders are +32 now but I wanted to make sure. Another thing I noticed on my 08 that is different from the 05. This bike like the 06 & 07 has a gear indicator. I wonder if Yamaha did more with the gear indicator than show you what gear you are in. Kawasaki uses this information to alter the fuel & ignition maps by gear in order to limit the power output in the lower gears (to control the tendency to wheely the bike in the first 2 gears). The 07 & earlier Hyabusas also used the gear indicator output for this purpose. If this is the case with the 06 thru 08 FJR-1300 5th gear probably has the most agressive CPU settings. I purchased a 08 service manual and the 08 bike uses switched ground inputs to the CPU to determine what gear it is in.
