Ive looked at some of these and found horror stories of the obd2 socket melting if used continuously with the Bluetooth transmitters. Make sure you do your research. It put me off and I'm looking to a scan have instead
This was just one of them http://www.pradopoint.com/archive/in.../t-22653.html?

I've heard some bad thinout the cheap ELM units and other cheapies from ebay.

Have a look here... http://torque-bhp.com/

I've gone with one from Scantool in the US as it turns itself off, so over heating is not an issue.

early days with scantool obdlink and torque app, but for those looking for transmission temps you need to add a custom pid. Seems also that PID codes changed about 2008 and you need a different pid code from 2008 on

I think this one is transmission oil pan and the second is torque converter atf temps (or vice versa) for pre-2008:
PID: 21D9
Long Name: Trans Fluid Temp 1 (or whatever you want to call it)
Short Name: TFT1
Max/Min: 220/-40
Unit: degC
Equation: (((E*256)+F)/256)-40

21D9
Trans Fluid Temp 2
TFT2
220/-40
degC
(((G*256)+H)/256)-40

I've also found this one, but not tested yet. I'm not sure it's right for pre-2008 vehicles.
2101
Engine Oil Temp
OilT
215/-40
degC
A-40

Also discovered that the range does actually matter for some error codes. For example, if the gauge fails for some reason some default to specific values (eg. -40degC or 220degC). But you can always change the display on Torque so it is right for the working range.

Any one found any more useful pids?

This on works on +08 models for Auto Trans Temp

21d9
Transmission Temp
Trans T
0/300
*C
(((((E*256)+F)*(7/100)-400)/10)-32)*(5/9)

You might want to change your temp range to -40 as when the temp gauge fails, the error value it returns is -40. So if you get that you know you've got a problem.

The formulas are different interpretations of how to convert the signal into the correct temp reading. I've been trying to confirm which one is "correct" but to no luck. Toyota will probably operate using degC so I went with the simpler formula as your formula is converting to farenheit and then converting back to degC. But have no idea which is correct

Engine oil temp doesn't work for me (2004), might on a post 2008 model

With the elm bluetooth unit and torque app can anyone confirm if you are able to get injector readings, egr, map etc or just basic reads

Dragging up an oldish thread, but I've just purchased one of these Bluetooth OBDII devices and am using the Torque Pro app. I can confirm these codes work with my 2008 D4D Prado.

Also have had no sign of the unit getting warm at all when plugged in... I tried the Torque Free app, but couldn't get any custom PID codes to work.. Definitely was worth spending $5 for the Pro version.

For anyone still looking, there is also an iPhone app called EngineLink that also allows Custom PID codes. Its about $7. It isnt as flashy as most of the others but I've tried it and it seems to work for Transmission Temp using the above codes.

Cheers,

Ryan

So this has got me interested does anyone have a recommendation or link to which unit to buy from eBay and which current app to use
