3.Difference between Techstream software LITE  and Techstream FULL

Have you ever been confused with Toyota TIS Techstream : Techstream FULL and Techstream LITE. Go on reading and get the answer yourself.
Full TIS Techstream vs Techstream LITE:
Toyota Techstream is sold in two “flavors”.
Full Version: The first is the Full TIS Techstream package which is essentially Toyota selling you a Laptop with the Techstream software preloaded and a special cable.
Lite Version: The other flavor is Techstream Lite. Techstream Lite is where you supply your own laptop and buy their special cable, and software, and you’re good to go. Their cable is very expensive, that’s why most users here would just have gone on http://www.careucar.com/ to buy it instead, essentially getting Techstream Lite to function on their computer for way less than the official route.
Comparison in details:

(just for reference! It’s talked about the genuine Techstream kit)
Device that is compatible Techstream software:
Most users of this forum would access this software by purchasing a cheap Chinese knock-off of the cable (called MINI VCI) used by Techstream. This cable is usually bundled with a version of the software, although there’s a good chance that you will find a more updated version on Torrent sites.
But, this mini vci with techstream is not allowed to do ECU programming and key making.
In short:
Mini vci techstream: customerization coding
Vxdiag vcx nano toyota: customerization, ECU programming and key programming
Attention to Chinese knock-off mini vci:
There mainly are two kinds of Techstream cable- Xhorse mini vci cable & clone mini vci.
If you would want to reset immo, or make customization to cars, need at least 2.0.4 FW with PCB design & chip security improvement and VPW support.
But the cheap copy v1.4.0 FW support only CAN but not K line VPW protocols. Also, there is no parts for v14.0 cable on PCB.
Special setup for mini vci cable from China:
Here is where gets is confusing for some.
In order to use the software with Chinese mini vci cable, you have to edit an ini file after install. The file is named “IT3System.ini” and it resides in the “Program Files\Toyota Diagnostics\Techstream\Env\” directory. The specific line of that file you have to edit is “TISFunction = 0”.
