Alright Charles, here you go:
Hardware Needed:
Tactrix Openport 2.0 Interface - either the name brand version for $169:

or one of the Chinese knockoffs for $50:

Additionally, you are going to need a 6 pin to 16 pin OBD cable, in order to connect the Openport 2.0 to the OBD connector on the bike. Here is one that should work:

You will also need a computer running Windows 10, either a laptop or desktop, preferably a laptop, unless you have a desktop set up in your garage and a really long USB cable to connect the computer to the Openport 2.0 device.
Software Needed:
HUD ECU Hacker - which is free and available here:

This will let you read the EFI map and download a copy from the ECU.
As far as connecting it up, you:
1.) Plug the 6 pin to 16 pin cable into the 6 pin RX3 OBD port.
2.) Plug the 16 pin connector into the Openport 2.0 device.
3.) Plug a USB cable into the Openport 2.0 device and plug the other end into one of the USB ports on your computer. It appears that the connection between the HUD ECUHacker software and Openport 2.0 device is sensitive to which USB port that you use on the computer, so you may have to try multiple ports until you find one that works.
From this point on, I'm not too clear on the further steps needed. It appears that you can read, copy, and send out the OEM EFI map to a tuner who will, for $30, adjust it per your instructions, and send you back the modified copy to be uploaded into the RX3's Delphi MT-05 ECU. But I'm not sure here, and it appears that this part has not been done successfully yet. I'll update this once we know more.
Hopefully this is enough to get you started.
