GS-911 / Re: Any remedy if getting 'ove...
Last post by JCtx - April 10, 2026, 12:40:41 AMApparently only 1300s have the capability of registering new batteries, and maybe changing to different types as well.
I've been reading many reviews about NOCO NLP14 batteries, and the majority of folks don't have any issues. It could be charging issues, since charging with regular charger that has a desulfating cycle, fries the battery. Hard to know. But a 2019 RT owner, which is basically the same thing as my 2020, since newer RTs have a different charging system, with a larger battery, so will go on my test mountain trip, and see what happens.

GS-911 / Any remedy if getting 'over-vo...
Last post by JCtx - April 09, 2026, 06:47:15 AMJust bought it today, and doing some research, several BMW riders (with 1250RTs) reported those warnings, and ESA not working. Since my bike is a 2020 R1250R (the naked one), I'm bracing for the same errors when I ride the bike tomorrow. But want to know if there's a remedy, or have to go back to the AMG I just removed. The main reason to buy the NOCO was that after updating my GS-911 to the latest version, the voltage threshold went up again to 12.5V, I can't do squat with the AGM, even though it's fully charged, it's the more powerful version (YTX14H-BS AGM), and I activated it myself, and fully charged it before installation, so it couldn't be any fresher. Even with my 5A charger connected, it's below 12.5V in less than a minute, so can't do anything. So frustrating. Why was it raised from 12.3V to 12.5V again??? I never had any issues, until the latest software versions.
Anyway, I looked everywhere on my Wi-Fi GS-911, and couldn't find anything related to the battery. So cannot change it to 'lithium', cannot register a new battery, cannot reset anything, and cannot increase the voltage threshold to avoid those warnings. Did I miss anything? If yes, please let me know where it is. Thank you.
Finally, can the higher voltage of these lithium batteries cause any issues on the bike, other than the codes? Newer bikes I think came with lithium batteries, so there must be the option, no? Or are those batteries' BMSs supposed to take care of any differences? That's supposedly the case with the NOCO NLP14, but maybe not. Really curious if it acts up on my bike. But if it does, and there's nothing I can do with my GS-911, would have to try to return it. Thank you.

EDIT: I want to change my login ID (to 'JCtx' too), but couldn't find how. Does anybody know how to do that, or who to contact? I didn't remember my stupid handle, so want to change it for the one I use everywhere else. I'm getting old. Ha ha. Thank you.

General Discussion / Re: K1600 Misfire but No repor...
Last post by Radian - April 07, 2026, 11:31:53 AMThough on my 2013 I did find the coil misfire indicated just after I bought the GS911 diagnostic. At that time I replaced only the defective coil and the bike is still without problems today and at 32k km.
I will check the exhaust temps with thermal camera (lucky to have one). But maybe I should just replace the whole lot because this (2017) bike now has also 32k on the clock and has not had a problem yet so likely it is due.
I also will just check the fuel. Somehow nagging feeling that this misfire started not long after I filled up at a fuel station I have not used for years.
Thanks for your response. Seems the Hex forum is kinda dead if you ask me.

Last post by botus - April 04, 2026, 03:54:15 PMpretty sure BMW were too lazy to add any diagnostics on the coils
the coil sticks are absolute budget junk on the K16 that are lucky to make 20 k miles - mine started to play up at 10 k miles and it had never even been out in the rain - modern BMW bikes are designed to just about reach the end of a very short warranty period and then pumps and electrics start to randomly give up - all part of the recent sick lease it and scrap it philosophy most manufacturers have moved too
throw a set in or if tight - measure the exhaust header outlet temps at the cylinder end with a laser thing and replace the colder ones

General Discussion / March 2026 update issues
Last post by phantom044 - April 03, 2026, 10:25:44 PMToday, I tried to code the sport screen and cruising lights on my 2019 BMW R1250 GS, but none of the coding attempts were successful. I hadn't experienced such problems before the March 2026 update. I've been using a GS911 for about 10 years, and my internet connection is good. At the end of the coding process, it gave a "coding successful" message, but the coding didn't actually take place.

General Discussion / K1600 Misfire but No report on...
Last post by Radian - April 03, 2026, 03:47:06 PMMy late 2017 K1600 GT now has a serious misfire
I duly logged in with my today updated GS911 and there is no report of any problems in engine controller.
I have one error relating to the security something (probably flat battery on the remote)
Is this possible and is there any advice on how to I proceed from here?

Engine related issues / Re: Throttle Body Position Sen...
Last post by botus - April 03, 2026, 10:04:24 AMTPS change does require the engine adaptions to be reset - stupidly written under Finishing Work - having told you not to both earlier
As for your other faults - plug in you GS911 head to the DME (engine), and look at live values for your CAT sensors and the trim adaptions with it running
if the CAT voltages aren't wobbling about between 200 and 700mV on both pot all the time and you have one set of adaptions running way different to the other Pot - I suspect one of your CAT sensors has died
the opposite pot is then told to run way to rich and the bike runs like a pig - don't believe you should have error messages - they can have, but I have three popped CAT sensors all of which don't throw error codes that MotoScan or GS911 can find

The news item in the upper right of the forum home page still links to the January 2025 GS-911 update, even though there have been three updates since, including the newest for March 2026.
well spotted - I've never even seen it here - they keep this up to date
