Firmware needs updating. Good news is it's an easy job. Bad news is the eTube software you need is Windows only.
And you'll need a computer interface. Which battery/Junction A are you using? If you're using the EW-67 Junction A you'll need a PCE1.
Problem solved - too many beers, I’d put the 6770 front mech on, replaced with 6870 and it’s alive!!
Cheers all, Matt
