@m750 - You're absolutely correct, probably should have checked that before I raised the issue here!!

Oh well the dongle will work with my wife's car at least.

Awesome app, and thanks for the fast replies


EDIT
@m750 - Hunting around on the web I found this in a Mitsubishi forum

Today I have borrowed one of generic OBD key. It is possible to get MUT communication (requests, commands and actuators with it)

Here is little how to
1. Open COM port of BT key, e.g. COM6 via HyperTerminal or write simple application
2. Set baudrate to 19200
3. Send ATSP0<CR><LF>
4. Wait for reply OK - (Bus Init..... OK)
5. Send A0<MUT ID><CR><LF> e.g. A032
6. Parse reply E0 <value> e.g. E0 80, so value is 0x80
7. Use formula to get the scaled value

Sure, the logging speed is slow, baudrate 10400, but the ELM based toys are really cheap.

The formula referred to comes from this table How much is involved in creating an MUT reading section/version of pyOBD? I'd be happy to help
