GS-911 / Re: Why was the minimum voltage increased from 12.0 to 12.5V???
« Last post by botus on Today at 12:01:56 PM »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
