This is from OV's website.
How it works -
We will provide you with our reflashing software that you install onto your computer.
Using the provided OBDII cable and USB License key, you will connect to your vehicle and run the software
From there you will download your stock ECUs data (Engine and transmission Data)
Then, we will send you a modified version of this data, which we have tuned.

OK, so you can hang on to your stock data at least. I think that leaves open the possibility of reverting back to it if need be. I wonder if TTI will offer the same functionality.

Hello
The ECU communication protocols of the RC200T and IS200T are the same.
ECU control module has a fuel octane decision is mainly from the engine knock sensor and road driving calculation engine load and etc..... then detect the occurrence of knocking level.
If we put 98RON tuned file but you use 95RON so the knocking situation has increased but the protection mechanism is immediately involved to protect engine and reduce the risk of failure, About this protection mechanism We raise the standard for durability.
I hope everyone knows what I mean

Tony, is the reversal process back to stock an option with your re-flash?

And am the First one in the Middle East
waiting for my tools and will also keep you guys posted.
I will be going for stage two since I got all bolt-ons including DownPipe (On the way), so my results will differ from Sheddy
Thanks to TTI for working with me on this one and also thanks to TTI UAE

When we connected OBD port and read out the ECU that's your stock data,you can use it for return to stock too via our tools.

I wonder if the TCU tune will simply incorporate higher line pressure for faster shifts. I think this is what it boils down to for the IS-F which apparently uses the same transmission but different tuning for more civility. Could be wrong..
