GS-911 / Re: Any remedy if getting 'ove...
Last post by JCtx - April 10, 2026, 02:40:37 AMI figured you cannot change the voltages, and neither on a car. But changing the battery type takes care of any voltage differences, along with setting the proper Ah rating. But our bikes apparently have none of that. Or at least the GS-911 does not have that capability.
I remember somebody saying a dealer can actually change the battery to lithium, since it's optional on some bikes. But again, the GS-911 apparently can't do that.
At any rate, those lithium batteries supposedly have an internal BMS that is supposed to compensate for any differences with an AGM battery, so guess we'll see with this NOCO unit.

GS-911 / Re: Any remedy if getting 'ove...
Last post by WayneC - April 10, 2026, 02:26:01 AMThe voltage requirement for coding/programming/resets is set in the ECU firmware not the GS911, it can even be set within individual job scripts in the BMW Dealer Diagnostics system, with the cars 14v is the minimum voltage required, the Motorrad division was a little slack in specifying minimum voltage & the last time I looked it was specified to be 13.5v. On the Husky Terra 650's released over 10 years ago you cant even do a service spanner reset without 14v
Regardless of model when doing any diagnosis I use power supplies/chargers which maintain 14v
The battery registration capability only applies to later more modern models & is to optimise charging curves & is also used to turn off/minimise charging when heavy on the use of throttle which improves throttle response

GS-911 Wifi / Re: "Ignition is not ON" error...
Last post by 03-K1200GT - April 10, 2026, 02:03:12 AMThanks for the info.
I've installed the new firmware and the Diagnostic for Windows, v2603.5 and Android.
I've connected a battery charger and the voltage stays in the high 12 volts.
Whether I start the Diagnostic with the ignition on or turn it on after the error message I still see the same behaviour.
In the former case I have never managed to see the 'Ignition ON' icon in the notification bar go green and the key indicator move to the vertical position. In the latter case the key icon goes vertical and the circle turns green for 1 or 2 seconds then the Ignition not on error appears.
I see this behaviour on both Windows and Android apps.
As I mentioned in an earlier post, 2 yrs ago, using the Android Diagnostic I had gotten deep into the functions. Now, I cannot even connect to these features.

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.
