F650 GS R13 / 2000 / GS911 - BMS-C: reset adaptations for TPS / IAC not working
stardust_59:
@Wayne
- I can only second Nicol and express Kudos for confirming my suspicion.
I read about the early SW version but I did not have the SW version numbers at hand.
Indeed the SW8000 produces a pretty docile Rotax sweing machine - having nothing of the zippiness of the carburetted Rotax in the Funduro.
Thus I hope my conclusion is correct:
SW5001 BMS + new injector = Fun
Hope I am not too far off.
I would not really care abut a bit more fuel consumption, really.
Once I can get my hands on the of unit I suggest to discuss the rest in private.
cheers

8000 3601 is EU, RON 95 & new injector
Part No 07658860 - 5000 3611 is EU, RON 95 & old injector
We have Haakon to thank for taking a pic of the old Moditec Dealer System screen when he first purchased his GS & was with the Dealer tech in the workshop, it had a table setting out the firmware versions/injectors for all of the single spark production, FYI the 5000 Series only went out to EU markets in the first batch of production, BMW then realised their error, there are a few here in Oz as we get EU spec machines
I am a little surprised re the Mfr Date of 1400-04-10, it is usually correct, is that a typo ?
Re a BMW updating the firmware to the 8000 series & messing up the VIN, I assume a Dealer not BMW AG ?, having a different VIN will not affect operation but it should have been easy for the Dealer to change the VIN to suit the bike, cant imagine what silly stories they would have tried telling, BMW have put incorrect/invalid VIN's in some bikes during production, we have a dual spark in that boat here in Sydney, GS911 picks up the incorrect character in the VIN the Dealer system does not hence it was never corrected to match the compliance plate on the frame
Re running 5000 series & a new injector, Haakon did try but encountered problems, he realised later he had failed to do an adaption reset/rebuild & unfortunately he did not have the opportunity to try again

Wayne,
thanks so much for the insight.
I was on tour over the weekend.
Tonight I swapped the SW5000 series BMS against a SW8000 series BMS (said BMS with incorrect VIN).
Voila - adaptation reset worked like a charm.
Also the strange behavior of the sluggish return to idle (with idle being too high) caused by the IAC has disappeared.
A new injector is underway and will be installed this weekend.
As for incorrect VIN:
Indeed this was BMW in Stuttgart Vaihingen (not a dealership but a BMW company outfit). So not a garage bricoleur.
Pending final adaptation to the new installed injector and test ride this resolves the maintenance issues for the owner of the F650 R13.
Yet I think it might be worth to have a closer look at the BMS with SW ver 5000: Data release: 50003611
Left to note that
Manufacturing Date: 1400-04-10
is not a typo.
It is as reported by the unit.
Maybe a silly programming errror in the SW 5000.
I also noted the following:
the SW8000 series BMS seems to add start functionality.
That is - when warm , just press the starter button and the engine will rev up shortly just as one would do when starting a carburetted engine. (A wee bit of throttle).
Did notice this when using the SW5000 BMS
I will get in touch with hexcode and we will see what to do with the SW5000 box. Might be some interesting forensics....
regards
Jan

Dear Jan and Wayne,
It has been a pleasure doing business with you guys :) Very happy to read all of the happy news! To many more F650 miles!! I'm tempted to get myself one (again) after all of this. Did around 55,000km on my F650GS Dakar before she came to an unfortunate sudden stop. Never to fly again.
@Jan: Will be in touch about that 5000 software driven unit...
@Wayne: With thanks to yourself and Haakon!
Safe riding,
Nicol

PS: Yes, I also noted that. And from the logs it would appear that is really what the controller is sending...
