I think I've decided to go far a manual switch, mounted on the RH controls so that I can use my judgement to control the fan. When I'm blasting along, it'll be off, when I come into traffic, I'll switch it on and leave it on. Hopefully I can then get the best of both ECU (old and new) set ups.

There's something else you might want to check too. I bumped into a bloke recently at a popular local bike meeting spot who'd had similar problems to you with his XB. He solved the problem by replacing the HT leads with some good aftermarket jobs. The originals had just deteriorated with the heat from the engine

Have a look at your manual - useless you use a independant

This is the first time I have used this site, so will give you a brief history: I have a 2 year old Ully which has never run right since new, and warranty has now expired ! It has had numerous visits back to dealer (who in fairness have been very helpful) and have had fitted bigger headers, Remus silencer, K & N filter, oil catchment tank and pro-fueller.
The bike has finally been running reasonably ok, but on its last visit back to dealer to clear up some warranty faults (inc. aux sockets not working which never have from new) this was connected to the ECU so hence a new ECU was fitted and a new download was available, which was suggested from the dealer that this would sort out all other running issues but.... after taking delivery of the bike and test-riding it, once reaching "running" temperature the fan seems to stay permanently on (even with an evening temp of 7C) and only stopping as you pull up in traffic which is when the fan would probably be on, on the hottest day in summer?! Once you pull away fan is on again by the time I reach 2nd gear yet doesnt run when the bike is stopped like it used to. HD say this is how its supposed to be to protect the engine, is this correct? Fan does not even come on if left ticking over for 10mins when engine is hot and then turned off like it used to. I cant ride this with the fan on all the time it will send me crazy!!! This is winter, whats it going to be like in summer. Anybody got any ideas?

p.s. Bike runs like s**t again, shall I suggest putting the old download back?

Go back to the dealer and tell them to put it back the way it was or its court action for them. Get a lawer to right to them as well.

Everything I've listed above will add another 10 minutes to the job but will ensure that nothing gets damaged.
I will watch/wait for your posts of future issues you may have with your bike

Handbags ready.................................
