I've just started looking at this issue, never mind how confusing their "Vehicle Service Information Read Me.pdf" is (it has been deliberately obfuscated so that you can't cut and paste from it - nearly every word in the document is a separate image of the word with over 200 on the first page alone).
It looks to me like they have swapped the columns "VCI Device Name" and "Manufacturer". So yes, they seem to be specifying the Opus IVS made "Mongoose-Plus" Toyota3 variant with BlueTooth (MFC3-BT).
It looks like there are two versions of Lotus diagnostic software available, please correct me if I'm wrong: older "Lotus 20/20" which supports Emira, Evora & Exige, and "EmiraDS" which seems to be Emira specific. I don't know why they specify the BlueTooth version when there is an equivalent wired version. Is there any other difference? Other than $120 on Amazon and $210 on the Opus IVS web site.
Now here is where I am getting into the weeds. The "Read Me" mentions that to use "EmiraDS", the "pass-through device" (think "computer to SAE J2534 adapter (OBDII)")
must support "Diagnostics over Internet Protocol" (DoIP). This threw me for a loop because OBDII is primarily a CANBus interface. But there has been a movement in the industry to get past the 1 Mbps (upto 8 Mbps in some cases) speed limitations of CANBus. So they have adoped 100 Mbps Ethernet as the new, high speed interface in amended ISO 22900-2. How is this accomplished?
"Four data lines and an activation line are defined for vehicle access via free pins at the standard OBD connector."*
The inclusion of DoIP requires significant new hardware in the car, including an edge processor and an Ethernet MAC switch. This new technology will allow much faster data transfer for upgrading firmware (upto 100x). However, it brings with it SSL encryption and certificates, meaning that as the owner of the car, you don't own the data. So you can forget about making a J2534 to RJ45 cable and plugging into your home network. The reliance on 100Mbps Ethernet makes the preference of a Bluetooth interface odd, in that anything less than BT 5.0 is limited to 3 Mbps, and BT 5.x is good for only 50 Mbps, half the 100 Mbps Ethernet interface. A wired USB 2.0, which runs at 480 Mbps seems like a better choice.
