Hi, I was faced with a choice a chip to unblock my Trek Powerfly FS9 2016. Since last year i ride with sensor on the crank, I had maybe 3-4 times error 503 (If I good remember) and after reset (turn off and turn on) error was disappear. I want to install chip because I want to register proper distance and speed on central computer.
Really, I don't know wich generation of bosch I have - I suppose 2nd generation.
I can buy speedbox 3 or speedbox 2 in similary price - but I afraid about 'reset procedur' in version 3 after each stop (I read about 'reset' procedure in case used speedbox 3 and bosch 4nd generation and I don't know If it will be similarly in my case)
