I have a simple question but maybe not possibly simply answered. So many threads here with issues of error codes, shutdowns, etc. with some of the Bosch controller and display systems available with derestriction devices. I have a Gen II Trek Rail 7 with the simple Purion display. I use a VOLspeed tuner with no issues whatsoever.
Now, I know VOLspeed says their unit will not work with the "Smart System" and such, but I've been wondering why the Purion setup works fine with the VOLspeed and Speed Box units. I've even had my Rail hooked up later to the Bosch software system to eliminate that battery conservation option if you have a headlight...which I don't and won't. My VOLspeed unit was hooked up when this was done, and apparently the update software didn't notice or react.
So, is it just internal components in the motor, the display model/design, or what that causes the Bosch update to kind of "catch" the presence of a tuner? It seems the simple Purion setup is immune to this. When the bike was new at the beginning of the year, I had all the maximum possible values set at that time and only went back later to do the headlight battery conservation option removal.
And along this line, why is the Flow App, Smart System, etc. so important? For me, once the system values are set to max, I can't see any other reason to reconnect to the Bosch software. That battery/headlight deal I did was actually kind of unimportant to me, but it gave me a chance to see if the tuner would be noticed. I get that owners can play with their personal parameters at will, but is this a big deal? And understand I'm not being judgemental toward those who want to play with such things, but it seems like it opened a can of worms for those who want to add a tuner.
And maybe I'm missing some level of awesomeness with these more sophisticated, newer systems that are available now, so understand I'm not claiming to be some kind of guru in this issue. And maybe my Purion display/system will self destruct tomorrow like the message device in all of those Mission Impossible movies and TV shows.
