As a courtesy for prospective users and a small sign of gratitude for all the info found here, I made an overview of what's written here. If I'm wrong, please explain. As for ELM adapters, I guess price says all about quality.
The ELM327, with all its known advantages, is an amateur level adapter designed for OBDII family of protocols. It was designed so good so can be used more widely, but this doesn't change the fact it is an amateur level device, that has lack of some features that are very desirable or even mandatory to work in full with modern Electronic Control Modules (ECUs). This statement above is generally applicable to the "derived" adapters, such as OBDLink MX or ELS27.
ELM327 is not capable of auto switching. But you can mod the adapter for auto switch with a minature relay and some more components. This modification will work with FORScan only. Note that Bluetooth components are more reliable than WiFi.
STN1170 based adapters like ELS27, Obdlink MX or Viaken "ELM V3" use another microcontroller that has more inputs than the one in the ELM 327 chipset. Here one input is hard wired to HS-CAN and another input is hard wired to MS-CAN. Microcontroller switches between inputs automatically if data from one of these inputs is requested. FORScan supports the STN11XX chip with a built-in MS-CAN bus support.
Should work, high quality products:

China clones that should work (so called "good" clones). Both PL2303 or FT232 are good if not counterfeit. In case of china clones, FTDI is generally preferable as usually more stable.

Many say it works, but they don't claim to support MS CAN bus without modification
- iCar v2 WiFi, Bluetooth (v3 WiFi N) with power off EUR 18,99 or US $11.17
- BAFX OBD2 Apdater
- OBDLink SX ($29.95 but it doesn't support MS CAN bus)
- BB77102 Bluetooth only supports HS
- There's VintPro p/n VINT-TT55502 from the same company and site as bbfly, but it's chepear option without FTDI chips.
Not working or not supporting MS CAN bus. Cheap eBay/Alibaba/AliExpress clones will NOT display or WRONGLY display data for: EVAP, O2 and HO2, B1S1 Lambda data parameters.
- ELM327 v2.1 that's not a clone anymore, but it is also not ELM327 anymore and not really compatible:
http://forscan.org/forum/viewtopic.php?f=4&t=22#p840
- bad clone of ELS27 marketed as "ELS27 FORScan" product:
http://forscan.org/forum/viewtopic.php?f=4&t=1904
- Super MINI or Mini Bluetooth Wireless OBD-II (transparent blue)
- F-Super is not based on ELM327, It is also not compatible with ELM327.
There is a device out there that is called "F-Super2" that has some features of ELM327 but does not support all protocols. F-Super 2 might work with FORScan but also may fail in some situations.

What I don't get is:
1 Forscan covers 180 modules
http://www.forscan.org/modules_list.html. Do all those that work really work with all 180?
2 Do all those that "work" have full support., i.e. give OK or text (indicating supported) and not ? (indicating not supported) for all those commands in terminal, sent one by one:
ATI, ATPPS, ATPP2ASV38, ATE0, ATL0, ATH0, ATR1, ATST32, ATS0, ATAT1, ATCF700, ATCMF00+, ATI (as in
http://forscan.org/forum/viewtopic.php?f=4&t=1575)
3 What's the advantage for simple users of pricier diagnostic tools and pass-through?
4 How do simple Ford-VCM OBD software or complex IDS software compare to Forscan?
5. Why doesn't Forscan licence or protects "Forscan compatible" or makes it's own adapters so that when adapter says "Forscan" that we are sure it's fully supported.
6. Can PIC18F2480 + FTDI in those cheaper (good) clones fully work?
