there are a couple people in the group making them (it's an open source design). can't help with discord but I suggest joining the FB group for dongles: https://www.facebook.com/groups/522090229588939This looks like an awesome tool. Too bad the macchina a0 is out of stock everywhere. Is the discord server or slack channel still active? If someone could invite me to those i'd appreciate it.
What sensor(s) or other hardware are needed to run a flex-fuel setup?
