Does it run badly, or Autotune just isn't reacting to your expectation?
Do you save the changes Autotune suggests and it just keeps getting leaner and leaner with each application of the changes or are just referencing back to the same base map fuel?
After the 2nd/3rd time I accept the suggested fuel trims the bike is running bad. When I roll on the throttle the bike will 'cough' through the BAK and the bike falls flat on its face. It had one of my cells at a -49 which means a 49% reduction in the amount of fuel the stock computer is calling for. That is at the 20%/4000rpm intersection.
The only idea Dynojet has come up with is the mounting location of the O2 sensor. I mounted mine in the same position Kawasaki does on the Euro bikes.
I removed my BAK and reloaded a base map. So far I've only accepted the first fuel trim and now the weather is cold so I'm done for the year. Next spring I'll try and get this worked out.
2010 Voyager 1700 ABS with heated seats, Grasshopper backrest, Kuryakyn highway pegs and an Ipod because the radio reception fades in and out. Also has a gear whine, fuel gauge that fluctuates too much and a pathetic cooling system.
