Bluetooth odb2 readers

Generally OBD readers don't work with Supra. Most Jspec supra's are Japanese-OBD1 which are next to impossible to connect to unless you have specific gear. Many have tried and failed to connect, and even when you do connect the refresh rate on the data is so slow that it's annoying to read data whilst driving. Late facelift Supra's are OBD2 so you might have some luck with that.

Has anyone ever plugged in a DLC2 adaptor into the under dash port and got any useful data with a handheld scanner?

Well the under dash port is just parallel wired with the one in the engine bay. So if the 3 or 4 wires that the protocol uses are presented on the right pins on the adaptor and the hand held scanner you have reads from the diag port in the engine bay, then it will work.
