I have a 2000 honda VFR 800 with 2 brother high mount exhaust. After doing enough research I ended up buying a used PC 2 from ebay.On the website of Power Comander they list 1 O2 Optimizer Controller which I eneded up buying.
I checked the bike today and see two o2 sensor. Does the the bike need 2 O2 optimizer or just one? and which one should i replace?
Since I'm certainly no authority and have a 6G, my comment is conjecture. (Also bumps the thread)
If the bike has two O2 sensors, you probably need two optimizers or resistors to be where you want/need to be.
My 6G does and other than VTEC, I don't think the basic operation of the motors is all that different. (Timing chains and gears not taken into account)
If your bike has two O2 sensors, you need two O2 optimisers. Technically they're actually O2 eliminators but Dynojet decided to rename them due to reasons I'll go into if you want me to!
