Ford replaced MS-CAN with HS2-CAN on DLC

Hello,
I bought a OBDLink MX Bluetooth several months ago. The Forscan software works great with my old 2006 Ford Fusion and will pick up the modules on both HS-CAN and MS-CAN. Thanks for developing a neat program.
I bought a new 2015 Ford Fusion Hybrid last month. I also buy the Service Information when I buy a car. I noticed the Forscan software does not list many modules. It does not find the ABS module, for example.
I looked at the wiring diagrams showing module communications. The car has three HS-CAN buses and one MS-CAN bus. A gateway module is used to interconnect the buses. There are a lot of modules! The MS-CAN bus is replaced by HS2-CAN bus on the DLC. Here is the pinout for the DLC:
Pin Name
3 HS2 CAN +
4 Chass Gnd
5 Sig Gnd
6 HS1 CAN +
11 HS2 CAN -
14 HS1 CAN -
16 VBAT
I do not know if this implementation is only used on the Ford Hybrid and Ford Plugin Hybrid.
I was able to access the HS2-CAN bus by using a terminal program to set the correct MS-CAN Protocol Preset on the OBDLink MX, then using the STPBR 500000 command to change to the faster baud rate. I was able to see data on the HS2-CAN bus using the terminal program.
According to the Ford service information, the gateway module handles communications between a diagnostic device connected to the DLC and HS3-CAN/MS-CAN buses. So supporting the HS2-CAN bus will let me see all the modules with Forscan.
I am suggesting Ford HS2-CAN support as a future feature of the software. I am willing to beta test.
