GS-911 / Re: Why was the minimum voltage increased from 12.0 to 12.5V???

« Last post by WayneC on April 15, 2026, 11:11:54 AM »

From your reply it appears the 12.5 volt requirement is driven by the complexity of the latest models.  My 2007 ST never had a problem with lower threshholds.  Hex should make the operating threshhold model-dependant.

As I stated in  th OP's other thread, the minimum voltage can be set by BMW in the ECU firmware so it is best to ensure 14v  regardless of  the model, BMW specify 1v on the cars & 13.5v for the bikes in the Dealer System

General Discussion / Manga Casino Pros and Cons

« Last post by HectorVat on April 15, 2026, 10:24:17 AM »

I've been testing  online casinos lately and stumbled upon  Manga casino
  Since they're licensed  (Curacao license, operated by Rabidi N.V.), I decided to check it out .
 
First impressions: The  design is  refreshing – lots of  magic vibes.  The site is  easy to use.
 
Games:  4,500+ titles from top providers . I'm a slots fan  and was  happy with the variety. Live casino  feels  high quality.
 
Bonuses:  Good sign-up bonus – match deposit  plus  extras. Wagering  around 35x (standard ). Ongoing promos  for regulars, plus VIP perks .
 
Payments: Multiple options . Withdrawals took 24-48 hours .  Caps apply but are  reasonable.  SSL encryption is solid.
 
Support: 24/7 live chat – helpful  when I had questions .
 
Overall: Solid choice  if you want a  legit platform with  variety. Just  play smart.

as various elements of the bike's systems do stuff the volts jump about - bike batteries are pathetic low capacity things - BMW dealer tools have high current posh "power supply" devices that hold the voltage right up there - the ISTA stuff has a 15 Volt minimum threshold for programming - below that things don't behave and the tool isn't meant to even operate

the newer bikes really need high volts, for the suspension especially - I'm surprised a CTEK charger I'm using mostly manages to hold the bike at 14.2V...

if you are dropping below 12.5 V expect things to go wrong - I doubt Hex increased the volt demand for the tool to operate - but its perfectly reasonable, if the system needs it, their tool needs to respect it - the idea is to service the bike not to introduce software issues

I'm no expert at this. Just wondering, considering the changes that can be made to displays and other settings on the newer bikes... I would assume it's of critical importance to maintain good voltage to ensure update coding is not interrupted/corrupted. Even on my 2010 parraffin model, maintaining correct voltage is a bit of a PITA but learned to live with it now.

I took a different approach: I spent $180 on a LiFePO4 battery (and specialized charger), in part to solve the GS-911 issue, especially if I need to use it on the road. But my point was why increase the minimum voltage required to begin with, when it wasn't a problem before. Seems stupid having to either buy a new lithium battery, new charger, or both, for something that was never a problem. Seems crazy, so just want to know why it was done, if not too much to ask.
Anyway, I already asked that question via the link provided above, since that guy didn't want me to post here, so I won't come back. If they lower the voltage again, great. If not, then it is what it is. Take care.

Maintaining a minimum voltage when performing diagnostics must be a fairly common thing as there are battery chargers having a specific "power supply" mode just for that purpose. My Optimate 7 has this mode.

What explanations??? I haven't seen any. On my other thread, I asked about issues with a lithium battery, and just mentioned a reason to buy it is because I couldn't use the GS-911 anymore with it. But I'm asking here why the voltage was increased, since nobody has ever reported a voltage issue on the BMW forums I follow.
But guess will ask at that link, and see what happens. But if there are any explanations here, I'd love to read them.

Just saw a video of a transmission calibration with a GS-911 where the threshold was 12.0V (software version 2502.3). Just like me, the guy had his battery fully charged, and after also hooking up a charger, his voltage dropped to 12.4V almost immediately as well. The difference is he could do everything. With 12.5V, it aborts everything. So why did you guys increase it, and by that much??? Never had an issue with the GS-911 for about 3 years with the lower voltage. Don't even remember what it was the minimum, but it was never triggered. Now I can't do squat with an AGM battery, PLUS a charger.

Hopefully it can be reverted back to 12.0V. Or at least 12.3V, which should be fine with a charger connected. Please let us know. Thank you.

It would be best to lodge a support ticket with Hexcode https://www.hexgs911.com/contact-us/ as the explanations of the reasons for maintaining voltage have not satisfied you & continuing to post on the forum will not ewsolve anything
