Central Vehicle Electronics/ZFE/GM issues / Re: Configuration to float lev...
Last post by Guilherme - July 08, 2026, 08:33:20 PMHi Botus,
If there is an option to choose the tank level sensor type—either capacitive (strip type) or resistive (float type), this choice should be independent of the specific ZFE module installed on the motorcycle.
The strip type sensor was used for only a short period; due to the fragility of the 400 individual circuits it contained, BMW reverted to the old and knowed float type system.
The ZFE unit supports and recognizes both systems. Physically, the input connection at the ZFE must be modified: the pins located at positions 34 and 35 (for the strip type) must be reconnected to positions 21 and 37 (for the float type). And we must change de configuration on the software.
Since the ZFE internally supports both systems, the GS911 should be able to read all the configurations available within the ZFE processor.

GS-911 / Re: Power save
Last post by GS Jim - July 08, 2026, 06:17:09 PMThis is a good idea, I have the cruising lights enabled and it causes all the lights (low beam, indicators/cruising) to go on when you key on instead of the low to stay off when till engine start like it used to. I disable the cruise light function when doing extended work but that is a pain to do every time. I will also unplug the headlight and then clear any faults after to decrease battery drain. Of course you pretty much have to run a decent charger anyway.

GS-911 Wifi / Re: XRDS TPM
Last post by GS Jim - July 08, 2026, 06:07:00 PMI have done this on my 2018 R1200 GS, I found it in RDC/Service Functions/Online Service Functions/Coding Functions/Configurations. I ended up restoring the original OEM settings as it kept throwing up weird warnings even though I was within the custom settings I made.

GS-911 Wifi / Re: XRDS TPM
Last post by botus - July 08, 2026, 04:01:06 PMI don't believe so, never came across the feature to play at that level...
start with the user manual for the bike ?
I have heard people claim BMW dealers have reset/recalibrated things - But I don't think that's a reality - not saying its impossible sometimes dealer kit has more features than third party tools and equally sometimes third party stuff can enable features dealer kit can't (see tyre temps and heated grip symbols in the cluster on older models)
on my car and most car systems its quite normal to have a user preference reference value - and its clear in the cluster that's there and the exact how, always explained in the user manual - its usual for things like snow tyres where you might want a very different pressure warning to summer tyres - where otherwise the nag of low level warning is just an irritant
never come across it, and indeed never had a warning on 5 BM bikes and 15 years of using BMW TPMS - until end last year when the 2011 GS irritated me with it when it was reasonably low - I could feel it way before the system woke up - hadn't ridden the bike for >3 months and the front was down to 1.7 bar and went off when I raised it to 1.8 bar till then never knew it could nag me
my 2007 GS only gave pressure reading and tyre temps - only other time I saw a warning was when it was flat from a puncture - I'd pumped it up, and it threw the nag during rapid deflation to fix it - which is when I thought they were supposed to overtly nag you

GS-911 Wifi / XRDS TPM
Last post by Lennart - July 08, 2026, 03:25:09 PMIs it possible to change low pressure warning in front and rear wheel on a 2022 1250 GS
Can I do it in entusiast mode ?
Do i need any other equipment ?

Last post by botus - July 06, 2026, 06:30:21 PMit should say if your ZFE is compatible for the swap - is it not under autoscan info section (its somewhere)
they don't do it with manual steps to try and get there like they do with the other tool
the GS911 tool is more automated in its retrofit changes - and maybe without you realising it backs up your settings and just does the code changes for you...
you must have a ZFE High module to have either or choice - that comes on RT bikes with cruise control and or ESA on stuff like a GS

GS-911 / Power save
Last post by info@knaake.nl - July 04, 2026, 02:09:47 PMI am wondering if and how we can request new features for the GS911. I would like to see the device turn off head and tail lights when in use. This will prevent a large drain on the battery I think.

Last post by GS Jim - June 26, 2026, 12:40:59 AMNo need to plug into bike just select Setup on first page of the GS911 Diagnostic app then Vin Usage.

Last post by GS Jim - June 24, 2026, 10:59:09 PMShould be on first page when you start the GS911 before selecting bike, Vin Usage.

Central Vehicle Electronics/ZFE/GM issues / Configuration to float level
Last post by Guilherme - June 22, 2026, 08:13:32 PMHi,
I'm trying to configure the fuel level from strip sensor to float but in ZFE Service appears just the calibration for strip sensor.
Where can I find the "Thermo Coupler FLS 08" to change the value to Potentiometer?
Could you please show me a step by step for this case?
For your information, all software updates have been performed since 2019, when I purchased the GS-911 scanner.
Thank you in advance.
