Back in for new (old airbox +icv) new spark plugs (Might as well while it's in) and new lambda sensor...they then keep it for the weekend and phone me last night at 4:50 telling me I need a new throttle position sensor  :( and they can't get one till the end of the week . Aarrrgghh, quick call to motorworks and get a used one sorted but missed the post ..so it'll go today directly to them ..but not greatly impressed with the garage, to top it all off they've lost one tech and the other is leaving at the end of this week. So no techs in the Aberdeen garage  :-\ .

And just to be my usual grumpy self, one wonders whether the TPS was the real culprit all along  >:(

Turns out my bike also has a poorly or non set up power commander that is contributing to the poor running ... this keeps getting better and better

If the Power Commander is jot functioning the bike will simply not start or run. It 'could' be a cable problem such that one or more injectors is not working.

If the TPS was flaky that will affect the PC, it gets its mapping feed from there.

If the previous owner was a dork or a tinkerer, they could have buggered the fuelling every 500 rpm all through the range.

It is as easy as 1, 2, 3 to put a zero map in the device and run the bike as standard.

1 Download the software - free and intuitive.

2 Connect pc to PC, copy current map (for wind-back and reference purposes).

3 Install a zero map. There's one in the software or on the website.

You can always go back to the copied map.

You can always get it 'properly' set up on a PC aware dyno.

The main dealer won't (and shouldn't) touch a PC.

Cheers , the tech did seem to think it's just the power commander so I guess if it's so fiddly taking out then getting it set up couldnt be the worst idea .
But this hasn't been the best advert for buying off eBay....guess my luck had to run out in the end ha ha. Limited service history and all that ...no mention of the PC. I think the honda dealer here has a dyno/rolling road ...Will look into that

The zero map option listed above really is VERY simple. I did it some weeks ago and it's a doddle (it took me longer to re-learn Windows).

The software allows you to see what the current map is doing to your bike and when you look at the zero map you'll understand why it's called what it is. There's also something quite satisfying on a man level about "remapping" your bike yourself even if you're just uploading someone else's.

Also, with the zero map installed, you'll be able to quash all comments ending "it's the PC that's the problem" - the zero map allows the BMW signals to pass through it completely unmolested - it does nowt, nothing, zilch or zero.

Give in to the Force and have a go - you know you want to.

...and if you don't trust yourself, borrow someone's 7 year old to back it all up before you muck it all up...
