I had the 2006 R3 Classic tuned a while back and it was running very rich in the lower RPM/throttle positions like around 2000-3000 rpm. Example: 70 mph in 5th is 2500 rpm and the bike would run 10.3-10.5:1 air fuel it should cruise around 14:1 air fuel. My mileage went from low to mid 40 mpg to 35 mpg. The back of the bike is covered in black soot.
I installed an Innovate air/fuel gauge and wideband o2 sensor to monitor the bike.
Day of tune in Phoenix AZ was 118 degrees elevation 1086 feet
I live in Payson AZ and the same day 98 degrees elevation 5,003 feet.
I rode down to Phoenix today to have him re-tune the bike and the 93 mile ride took 1/2 of a tank of gas that's hardly 30mpg. The bike was running rich on the ride down.
He put it up on the dyno and everything looks good...WTF.....under 20% throttle was running 14:1 and over 20% throttle was 13.3???? Right where it's supposed to be. He made a few
tweeks to the map but nothing major.
Does the temperature and elevation at the tune shop being different than where I live be that big of a deal? Don't these bikes have sensors that monitor such things?
Being adaptive does running it on the dyno at 1000 feet elevation make it remap the OEM base map while he's tuning then I go to 5000 elevation and it remaps again? Maybe a sensor is
screwed up. I have the new blue TPS set to .63, stepper set to .75 throttle bodies are synced.
The air/fuel mixture coming home to Payson was spot on I'm wondering in a few days if that won't change.
I hope my explanation is clear. What the heck is going on???!!!
