O2 Controller - Need urgent help
Hey chaps
Some might recall my recent dyno run that looked incredibly lean. As a result I ordered up the O2 controller and Kev mod which arrived today. I just fitted the O2 controller, went for a spin and it is completely unchanged. No difference anywhere. I even stopped by the roadside to unplug and plug it all back in again but really there's no change for better or worse. This gives me a major problem. In 4 days I leave for a 1500 mile round trip to Skye. If I can't figure out this controller by Thursday, this year's trip is going to be by car. I never did think my XT was too juddery, but I did expect to notice some difference with the O2 controller. Any ideas? -------------- Edit: I noticed that Kev states "The closed loop is used for emission control, it comes into effect after a coolant temp of 70 degrees C...". What does the bike do between cold and 70C then? My test was only 5-10 minutes as I expected immediate results from turning the key. Could it be that the coolant didn't reach temperature?

Inspired partly by my desire to attack the bike with wirecutters, and partly by the tumbleweed blowing across this thread, I headed back to the garage with the Kev mod.
My theory, made up entirely of guesswork and assumptions, is that if the bike at cold start doesn't use the closed loop, it must use the open loop. Seems reasonable. So, fitting the Kev mod should mean that when the bike is cold, I can adjust the resistance with the Kev mod and notice a change, right? Wrong. Still nothing. My lovely wife said as I trudged back into the house, "Why don't you sell the XT and get a bike that just works properly when you buy it, like all the other bikes you've had?". You know what, she might just have something there! O2 controller and Kev mod for sale. Oh, and an XT660. |

2 hours and 35 minutes is hardly a long time. Please remember that Kev is 12 hours adrift of the UK, he works for a living too. He usually responds as soon as he can.
Patients, is a virtue.

What I meant was "If no-one's got any ideas I'll go and crack on myself". I think when I posted that there had been 25 viewings and no suggestions and I knew Kev wouldn't be online for hours.

you wouldn't happen to get any error codes?
Certain error codes will make the CDI go into a "safe mode" where it totally ignores whatever O2, air intake temp and other sensors tell it. If not, Kev will be best-placed to help you out. |

I didn't see anything unusual on the LCD display, if that's where an error code would show up. |
