This can be anything the ECU monitors examples include rpm, coolant temp, oil temp, inlet temp, air fuel ratio etc. The one you want is an ELM327 one.   They come in various shapes but with where its situated on the '86 you either want a short one or some sort of extension or its likely to hit your left leg when driving   The one I got was this one from fleabay (http://www.ebay.co.uk/itm/231164930452?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649) you can get cheaper ones but the £8 one I bought last time stopped working after about 6 months so I thought I'd risk a bit more this time   Plug in the adaptor   You can find the connector for it under the dash, look above where your left knee would be when seated and you should find it. Note the connector is shaped so you have to get it the right way round   Pair the ODBII device to your Android device   Power on your car to power up the dongle, I did it with the engine running so I knew it would have power. Go into your device settings and make sure bluetooth is on and search for new devices   Mine appeared at first as a HEX address a bit like a MAC address ie AA:11:22:33:44:DD but then updated to appear with the name OBDII   Select the device and it should ask you enter a pairing code, for mine this was 1234, some use 0000, check with your supplier if neither work   Start Torque   When you start Torque it will ask you to choose the bluetooth device, select the adaptor you paired above.   If you then select Realtime information the Torque App will start displaying data received from your car, rpm is the obvious one to check, press the go pedal and watch it rise !   You can configure the display to change what is shown, you can also modify what data is logged on a journey   There is also some point where it asks for setting up a profile for your car, it does this when you first use it but as mine is already setup I can't remember what it asked.   To reconfigure the display press and hold on any of the dials to get a menu that lets you delete, move, resize, change dial type   To add a new display press and hold on an empty area of the screen and you get a add menu   Oil Temperature   Although Oil Temperature is a normal ODBII PID our car doesn't use the standard one, it uses a bespoke one instead.   The Torque App can be configured to monitor this custom PID as follows   Open the Torque app and then hit the menu button.   Select "Manage extra PIDs/Sensors" (should be second from the bottom).

Hit the menu key again and select "Add custom PID".   Enter the following information   OBD2 Mode and PID: 2101
Minimum Value: -40
Maximum Value: 215
Scale factor: x1
Unit type: C
Equation: AC-40
OBD Header: 7E0 Hit ok. The oil temp parameter will now be available for logging and real time display.
