Came across a website today that has some interesting info regarding OBD2 ELM327.

I have a ebay knock off bluetooth OBD2 ELM327 v1.5, according to this website that version of ELM327 doesn't even exist. Although in Torque Pro adapter status it states version 1.5
So what chip is it actually running?
