It's BUEOD. It's odd, because the bike is a 2007, the engine is the later Thunderstorm 1200, and Buelltooth informed me, with this file type, it's a 2008 model!
As you know Buelltooth have a number of pre made tune files suitable for different after market exhausts. They didn't recognise mine, which is an SGI ( stainless ), have you heard of it? Anyhow, I picked their Jardine RT1 because it looked similar in size, and had one outlet pipe the same as my own.
To be honest the bike previously didn't run that bad, a little irritating at 30mph, but out of town that disappeared, more so was at about 50mph - 62mph, where it felt as though it needed more fuel. I followed all the tutorial, loaded the Jardine file, and hey, those issues all sorted!!
1) start up and tick over good
2) Throttle response good
3) No popping on the over-run
4) A good return to idle when blipping the throttle
The AFV to begin with was 75.2%, I set the AFV to 100%, after a 270 mile run it was back down to 75%, I think the closed loop learn had done this. I then tried their recommended procedure to run open loop ,without purchasing their recommended Baro Kit initially. The bike started , but is now unrideable, the tick over moving at will between 1000rpm, and 1300rpm, so on the road it lurches forward the falls back. I couldn't believe it when the original file was not in the android file manager anymore! I have removed and replaced the spark plugs, 1 1/2 hours! the old ones show a good colour indicating a good burning mixture.
You've surely guessed I have limited knowledge about computer tuning, but what I fail to understand is that ,if a new tune file loaded, completely overwrites the previous one, why then when I reloaded the Jardine file, which I do have the original copy of, and I know the bike run well with it, did it not rectify the problem?
I welcome your advice,
Cheers
Nick Davies.
