Here's my setup:
- 2007 13A
- Two Brothers slip-ons
- Stock air box with K&N
- Power Commander III USB running map for the two Bros from PC website
A few weeks ago, I read on this forum that most folks disconnect the stock O2 sensor when they install a PC on the FJR. So to verify I contacted Dynojet and they said same "Yes, disconnect O2" they said as long as I don't get an error from bike because it's disconnected I should be fine.
Well....immediately after disconnecting the O2 my gas milage went straight in the "crapper".
Before with the PC and the stock O2 sensor both connected I was getting 47-50mpg consistently across all types of riding conditions. Suddenly now I was only getting 41-42mpg.
So I hooked the O2 sensor backup, rode another tank of gas but it did not go back to the original milage. I even tried "leaning" out the PC to save a little juice but nothing seems to make a difference now.
I called Dynojet to see if they had any ideas but they were no help at all.
Has anyone out the experienced this before? I'm at a loss now because I've tried everything I can think of and nothing seems to work.
Any ideas?
