Central Vehicle Electronics/ZFE/GM issues / K1200S 08 Fuel Strip calibrat...
Last post by miamicycles - July 22, 2026, 06:16:05 PMHello,
I Need some insight, I have just replaced the fuel strip on a 08 K1200S K40, and when trying to do calibration process, it keeps saying that there is an error with calibration process. The strip is new and dry.
could there be something wrong on the bike side?

Technical / COMBI LED RETROFIT - PERSISTEN...
Last post by Julio - July 22, 2026, 06:07:09 AMGood day, I have a problem that is driving me crazy.
I installed LED indicators on a 2017 S1000XR.
Naturally, this would throw the "LAMPS" error as it was coded for incandescent bulbs.
When I did the LED Indicator retrofit via GS911, the error is now "LAMPF".
Upon checking, the rear lights stopped having the open circuit error, but the front lights are still displaying open circuit errors.
Weird, it's as if the LED retrofit coding only worked for the rear lights and not the front?
Any ideas on what to do and check?

I know the argentinian strip sensor. I presented this solution for the people of GS-Forum in Germany and many coleagues there are using with good results, despite the low accuracy.
The prices are quite the same. And I like the reliability of the float system....

In the How To menu at the top of the front page amongst other things is a manual pdf
At the bottom of the front page there is also a Using The GS911 menu with further info

ezCAN / ezCAN Mojave Fuse Settings
Last post by key - July 17, 2026, 11:20:10 PMHello all. I'm running an ezCAN Mojave as a means to power an auxiliary brake/taillight on a 2025 BMW R12 nineT. Taillight is connected to the ezCAN yellow circuit; all other circuits are unused and have been disabled.
The default fuse setting for the yellow circuit was originally 5A, and at that setting everything worked as expected. There was, and still is, a 1 or 2 second delay between the illumination of the OEM lights and the auxiliary taillight when I power up the bike, but I assume that's normal behavior for the ezCAN. Please advise if not.
Back to the fuse settings: ezCAN's diagnostic function shows that the taillight uses a peak amperage of about 0.5A, so based on that I decided to reduce the default fuse setting from 5A to 4A. After doing so the taillight no longer powers up unless I power-cycle the bike, at which point the tail/brake light works on the second attempt. Seems that powering the bike on/off resets something within the ezCAN which then allows it to function normally. Not sure what that might be other than the fuse protection setting. If I change 4A back to 5A, the problem goes away.
This might be analogous to when I complain to the doctor about how it hurts when I poke myself in the eye and he tells me the cure is to just stop doing that. It's not really a problem to have to use the 5A fuse setting, but why does a low-amperage device like an LED taillight need such a high setting to operate correctly? The taillight wiring harness uses conductors that are as fine as frog hair, so I'd prefer to not set the fuse any higher than necessary. Anybody encountered anything like this before?

Menu items are specific to each model so a list is not really feasible
I notice you did not state your bike model so it would be impossible for anyone to assist you
Do hex provide a manual as did not get one and cannot see anything on their site. Also took me 4 months to get approved on the forum 😂

Last post by botus - July 17, 2026, 10:58:10 AMQuote from: Guilherme on 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.
thats how the other tool offers things - the way I understand it - the GS911 works out there is no point allowing you to check a box to make that change - if the rest of the bike / other elements of the coding will not allow it to function - so it just informs the user the bike isn't suitable for the swap
Actually - that's exactly how it is with the ZFE Basic High in my 2008 R1200GS - older iterations of the Red GS911 software used to allow me to swap that configuration - but it never functioned, now it flags isn't not suitable with a message
@Guilherme - are you fully aware only ZFE High units allow you to successfully do the swap to a Float - and that its way less accurate and either or sensor is still they way they build them - the best way to fix the strip sensor bikes is to use https://www.fuelsensortech.com/en

General Discussion / New Look, Same Out-of-Date New...
Last post by karlh - July 16, 2026, 10:04:25 PMWith the website's new look I thought the news item link in the upper right corner would be updated, but no such luck. Your link to a January 2025 firmware update is 18 month old. At least three updates have become available since that item was posted. I even discussed this with one of your representatives at this year's BMW MOA rally in Vermont, but apparently it fell on deaf ears.

Last post by gixxerchuck - July 16, 2026, 12:17:30 AMHas anyone documented the full list of the menu items and what the commands do.
Saw a bit for enabling sports dash but would be useful if someone had mapped the options with a description of what they all did
