[QUOTE="Fred W, post: 1248863, member: 3828"] Nice! Thanks John. And I agree with them. The 3rd Gen FJR fueling feels pretty much like where my 1st Gen was after adding the PCIII and a custom map. In other words Yamaha got it right on the 3rd Gen. No need for an add on Power Commander type box at all. You might ask the DynaTune guys why it was that they designed the PCIII to pass the O2 signal through the box since they intended for you to disconnect the signal anyway? They could have accomplished the disconnect automatically just by not passing the signal through. Maybe it comes down to not violating EPA rules about disconnecting emissions circuits. Which might also be why it is not found in the instructions to disconnect it. [/QUOTE]
