I also just bought an 07 FJR a few months ago and installed a brand new PCV I downloaded several maps but are currently using the one right from Power Commander. Iím very happy with the results No more herky jerky throttle. I also did the throttle return spring unwind which I really love the results of that as well. I unplugged the O2 sensor as the instructions say to. I donít think power commander even offers the PC3 anymore. I think itís PCV or one of the other styles of fuel tuners. Like Dobeck Performance one. Which I used in my first 07 FJR and it worked great as well. You donít need the auto tuner for the PCV to do itís job. I also used a PCV on my FZ1 with out the auto tune with great results.
