Title: TPS settings on K1200RS -vs- K1200LT
Post by: Jean Lussier on March 01, 2015, 01:21:42 AM
My question is rather technical and is related to differences on GS911 settings / values in the TPS adjust screens for K1200RS/ K1200LT Motronic platform.  Tests mentioned below were done using GS911 classic-Yellow unit with software Version 1411.2 plugged into a Windows 7 PC with a USB cable interface.
 
It has been accepted / known for many years that Motronic MA2.4 would expect a base TPS setting corresponding to 0.34 to 0.38 for most BMW models.  In GS911 real-time values screen/log this would match an opening of 0.64 degree.

Having done a lot of work on many K1200RS Throttle-bodies (1998-2005), I was satisfied with the GS911 procedure to confirm TPS adjustment as this would match other methods that I had used in the past to get 0.36 volts.  Recently, I had to use my GS911 to check TPS setting on a K1200LT (2005) and was surprised  to see that GS911 expect a value of 0.42 volts in order to be in the middle of the green range (roughly 0.96 degree).

Could anyone at Hexcode explain why the GS911 software expects such a different value between K1200RS and K1200LT selected option on entry?  I fully understand that some internal details may be trade secret of HexCode, but I cannot imagine this was done arbitrarily without an official reference from BMW.

Thank you for your diligence in this matter.

P.S.:  obviously, on both bikes (K1200RS , K1200LT)  I have followed the requested steps to removed Idle-Actuator when needed.

After more than 10 days from my initial post above, I see no reply from the staff of HEXCODE.
I am assuming this lack of response means I need to send an email to HelpDesk (support) - is this correct procedure ?

Why not note where it is and then try what they recommend. You can always go back to the original setting if you are not happy.
