Hello!
I've ordered a VAG-Com Cable with FTDI chip to use FreeSSM. After some researches, I've found the following compatible models:
Legacy®/Liberty®/Outback®/Baja®, Impreza® (incl. WRX + STi), Forester®, Exiga® and Tribeca® starting with model year 1999 up to model year 2009.
Model year 2010 is already supported, too, but some Measuring Blocks may be missing and some Diagnostic Codes may not be displayed as plaintext.
I'd like to know if someone with 2011 or higher LGT model could use FreeSSM succesfully. I've ordered a VAG-COM cable, but I think it won't work because FreeSSM uses ISO 14230 protocol (KWP2000) and 2011 and higher Subaru models uses ISO 15765-4 protocol (see Subaru bulletin on https://obdclearinghouse.com/Files/viewFile?fileID=1594)
