Hi, the circled connector is USB to allow for firmware updates.
You will want to uninstall the LED display and ECA you currently have wired to the GM ethanol sensor.
The GM ethanol sensor itself you will keep, as the Motiv ECA will plug directly in to it.

Is there any way to use LED display with motiv ECA??
the insatll guide said...
Motiv ECA pins are going to black connetor of DME. it means original factory connector?? or jb4 black connector?? or doesnt matter??
No way to use LED, however you ca now log E% in MHD.
This must be wired to the stock DME connectors. However, if you are using a JB4 as well you will need to contact @Terry@BMS for support.
MHD / Motiv only supports using the ECA with flash only.
If using the Motiv kit with the JB4 you wire it up per Motiv's directions, and then we have special JB4 firmware and BEF that reads the E85 content off the ECU via CANbus. The wire going to large black #10 isn't needed/used in our implementation. Connections can go on the OEM harness as they are easier to reach that way.
I've been running Motiv Flex Fuel since this past summer. As winter came, I ran the tank back down to E10. Weather is pulling back up and my car is together for now, so a few drives this week, filled up at Sunoco E85 and my Fuel-IT BT app says we're back up around E55 at the moment.
I want to thank @jyamona for superb work on this, along with others that helped him along the way (I know a few names but surely not all so don't wish to list any). Jake this thing just flat out works like a champ. No fuss no muss. It's a non-trivial upgrade to put together. I know it was a bit of a long road once it was working, to get to initial release but the wait to get it all right was worth it. Job well done and I just want to say once again, thanks!!

I concur wholeheartedly. I am so spoiled with flex fuel and the ability to just add and go.
I wish more people would get it to justify continued investment in the DME platform.
@jyamona, curious if you have a roadmap for any other features this year? I know getting to the flex fuel launch was a long road, so I understand apprehension about giving any timeline, but a sneak peek of anything you have in the world would be great.

Thanks for the kind words guys, glad you all are enjoying it! Hopefully more continue to try it out and enjoy the benefits.
Is there a limit to the flex capability? This may have been covered before.
Assuming there is a fuel system that covers the needs obviously, but is the system able to adjust for E60+? Say all the way up to E90?
No limit to the functionality at all, it can adjust from E0 - E100.
I cannot imagine why anyone running ethanol would not want to have this on their car, to be quite honest. The convenience factor is great, not to mention that you just don't have to care what comes out of the pump. It's a slam dunk purchase decision.
