There is no post anywhere, either here or on their crap explanation video. There is no technical data explaining how to use the x-series or why the settings are what they are.
#1 - If it doesn't connect or it stops connecting, disconnect, reconnect, etc. Do not mess with the settings internally. No Can-Bus vehicle will have issues other than the random connection issue.
Make sure the first ecu setting in the gauge controller is set to #7, set the other ecu setting (What the controller identifies as) to #4, this will never interact or overlap other ecu's
The can-bus system works as 7x* - * being the sub-computer in the network, 1 will be the ecm, 2 is transmission (unless its included into the ecm) 3 will be the fuel control module if the vehicle is equipped with one. So setting the controller to 4 will be perfect for any vehicle.
If you have also messed with the bit-rate, the maximum data rate is 1Mbit/s, but this is the raw rate, there are 46 "management" bits for up to 64 data bits. This reduces your net data rate to about 580kBit/s.
The bit-rate is something you will have to mess with because I can't really remember right now.
#3 Connect to the vehicle, but do not start a datalog.

#4 Click "Repoll for parameters" as shown in the photos

#5 add the wideband from the parameter list to your logged PID's, it will show up as a fourth, third, or second controller. But will always identify as 7x4

So, now that you know more than the company selling these apparently does, enjoy your new wideband.
