So recently I've been using my tiptronic gear more than I should, gotta have that V8 pop!

Anyways, I was thinking about how hot the transmission was getting. Also how hot the engine oil, trans pan temp, trans torque convertor temp... etc.

I wanted to get a performance monitor screen, but that option was way too expensive, and the look just didn't fit the car, especially for the casual interior.


Searched here and there and found that the Toyota Techstream doesn'tgive trans temp and the readings I was looking to obtain.

So the alternative I found was to get an OBD2 communication hardware that would plug into the car and wirelessly transmit tons f data to your phone, whether iPhone or Android, was iPhone in my case.
You could either get a WiFi type transmitter device or a Bluetooth one. The Bluetooth transmitters I found to be very very slow and lags while transferring the data.
(For example, if you transmit RPM to your phone, you'll find that when you rev your car the gauge on the app will not be anything close to real life time readings. So I went with the WiFi transmitter.

I didn't get an el cheapo one because data transfer speed was my #1 priority in this experience.
So I bought mine off of these guys, it costed me $33.99 with free 3-day shipping. It's called "Vgate iCar 2 OBD2 reader ELM327".

Now to the trying it out part. You just plug the device to your car, look for it under WiFi in your phones' settings, and you'll be ready to go.

The second important part needed is the software which is what will take the raw data and code from your cars computers and sensors and give them a friendly and nice visual lay out.

My experience was with 2 different apps, of course there is a lot of apps out there, but these were the ones I cared to try after reading users reviews.

1- OBD-Fusion $9.99
This app is pretty cool because it allows you to enter your own custom PID's(Formulas made for your vehicle that would extract specific data)
This app was pretty great, a lot of visual gauges, and it offered standard data such as;
RPM
Speed
Engine coolant temp
Boost/Vacuum
etc.

It also had the feature of reading Check Engine codes and clearing them.
This app only lacked more performance oriented readings.

2- Dash Command $9.99
This app was pretty cool as well, only problem with it is that it doesn't support custom PID entries. But it had an awesome performance category. Such as:
0-60 times
Estimated horsepower
exhaust temperatures
etc.

They both had data logging that is very useful to record the data to review later.




It was challenging at first to find a custom PID that would pull out my transmission temperature. And after a couple of tries, I think I've managed to make it work, although I might need some confirmation from fellow people who'd know where about the trans temp should be on our cars.

This is the formula (custom PID) I used, that I got from a Toyota RAV4 user that I figured should work similarly. This is for anyone who wants to do this (that is if it is correctly giving the trans temp and not any other temp in the car.) Although I can confirm that it was always a different reading than engine oil temp, intake temp, engine coolant temp.







Anyone with a helpful comment regarding the AT temp please chime in, whether there is a pan temp, torque converter temp or just a one temperature for the transmission.
The trans temp that I was getting were around 140F and reached 190F after playing with the car for a bit.


What did you get on 0-60 times?!
thought you'd never ask!

It was my first time using the app, and I am not sure how accurate the data was.
I got a 0-60 in 6.6 sec, can't remember my 1/4 and 1/2 mile times.
And I was pushing 273 horses when I peaked at around 3,000 RPM.

This is very cool functionality ... nice discovery.

will this work with iPhone 6? I had the torque App on my optima but used an Andriod phone and the results were good. I had the layout on my phone then used a 7" China tablet that would show boost, engine temp, coolant , etc. it was great. I'd like to get something for the GS

I'm sure it would. I used an iPhone 6 Plus.

These are temps I got after a 15 min. Drive.

2 far right red gauges, upper one is in Fahrenheit.
Lower one is in Celsius.

so which app did you decide to go with? you mentioned two in the previous post

I went with #1, OBD Fusion. Since it has the custom PID entry, which you need in order to read AT information.

Hi, I am new to this forum. Please can some one help me. I have a 2001 3uz fe engine (I am pretty sure it is the engine of a Ls430). I am looking to use an OBD 2 reader for the temp, rpm, speed etc.

I need to know if an OBD 2 will be compatible with my engine AND if yes WHERE do I insert it???

Your help will be much appreciated

Legender

^^^ yes, OBDII (2) will work on your vehicle. Any standard reader from ebay will support your vehicle. The port for plugging into us underneath the dash, under the steering wheel. There is only one port like it so easy to find.

Hi,

Do you have the Mode and PID and Equations for setting the Transmission temperature for LS430? If so, can you update this thread?

Thanks,
