You can use Manual mode without a device attached - just send your setup to the bike & leave the screen at home. I changed Manual Turbo settings to 80/100 & kept it in Turbo.I read the manual last night for it .. all the confusing icons and options all now make perfect sense and are actually really well thought out and entirely logical ! To get the most out of it and avoid initial confusion, it's definitely an RTFM app.
I didn't spend much time appreciating the "auto" and the graph settings of the manual . Did you leave all that on default or did you change things ? You said 80/100 ?
Are you using the phone on a mount and taking any info from (I think it suggests gear changes an things, especially in the extended 6/9 speed mode) it or just stuffed in pocket and using it as your power control brain ?
In Extended Manual & Auto you need the device attached and yes I have a Blackview BV6000 on a Quad Lock Out Front mount.
I haven’t tried the Automatic Power Mapping or Zone Variation yet but will report back. If you want to just ride then maybe don’t bother with any app but if you want to explore & adjust parameters to suit your terrain & riding style then there’s nothing better.
