For all you 3rd gen owners(unconfirmed) out there and you beams owners (confirmed)......

YOU CAN NOW USE YOUR OBD2 PORT!

Who wants to know how??

Are you guys ready?

it started with some internet research on communicating with jdm ecu's and the protocols they use. Apparently, even though they have the same plug, they are not obd compliant. As the research contined, I found a guy who had found a way to get his import 2jz with vvti to work and I thought there is no reason why this wouldn't work also work for us.

So, I should preface this by saying that this will not make your car readable by emissions testers where it would otherwise fail, but gives you, the end user, the control. For $28 you can have this fully operational

Step 1: go out and buy an OBD2 Bluetooth adapter. In this case, the one I purchased was this one from Amazon the Bafx PIC18F2480 - http://www.amazon.com/BAFX-Products-PIC18F...=obd2+bluetooth

Step 2: Purchase the 5$ app "Torque Pro" from the google play market for Android. (For you apple guys, the App Store does not have this exact app on there so I am unsure if any of the steps after this are valid) Any android powered tablet or phone should work here.

Step 3: Inside of the app you can create car profiles for different vehicles (This app is incredible and is by far the most useful thing I've ever bought as an app because this app and the adapter can be used on ANY obd2 car) In the vehicle profile at the bottom of the profile page is a line that says Very Advanced ELM327. There is a line in that section to add text. The following text should be added to that line:

ATIB 96 \n ATIIA 13 \n ATSH8213F0 \n ATSP4 \n 0100

Once that is complete, hit SAVE and go back into the app. The app is now configured to see the JDM ecu's (that code changed the searching frequencies and some other protocol stuff in the app to be able to read the JDM ecu's)

With the app configured and your OBD 2 adapter plugged into the port on your car, you can now read all of you engine data with the the Torque app. Insert vehicle parameters to get HP and TQ estimations, Fuel economy, timing advancement, speed, the list goes on (really really nice app)

There is also a check engine light portion of this app where you can scan the ECU for codes so it becomes a scan tool as well.

Evidence of it working


So, are we to the point where we can pass emissions testers? No.
But we can better troubleshoot our cars, and even do some rudimentary tuning because the possibilities of the app are INCREDIBLE. Add A/F ratio stuff you name it.

Hope this works as well for you fellas as it does me!
