Used TechStream software from V8 to v10 for years. Put something useful tips for you all. It’s mainly about using Techstream to customize settings on the car Scion FR-S 2013.

How to install mvci mini vci toyota 10.30.029:

-the Techstream cable from
A uk site. It’s here:
In fact, settings are supposed to be changed by going to the dealer. and there is a page in the owner’s manual that describes the settings. I just wanna try and do it myself and learn more about the car
– Cost and delivery
€25,free shipping from China, with one-week delivery

– easy to install
No, the install CD comes with a video of a walkthrough of the entire process. Includes how to install the driver, use the supplied software patch to disable activation, how to access the car.

-OS to run with

I installed Techstream software on Windows 7 32 bit on an older laptop and HP mini netebook

– not the genuine TechStream software
It looks like the actual Techstream, but just a copy of it. Cracked already, so runs without issues.

-ECUtek cable vs mini vci
1 Both cannot change the same settings. Mini vci has a chip for only flashing tunes.

2 mini vci cannot program ECU maps as the Ecutek cable, but this is for customizing settings only like a dealer would use.

– Torque vs Techstream
Torque is cool for monitoring live details from the car, logging and clearing error codes but not allowed to change settings on the car

– my FRS listed
the FRS for 2013 and 2014 was available in the drop down


-settings can be changed
A Bunch

Here are the screenshots of the main selection screen once it connects to the ECU

From here I clicked the customize settings


Here is the window that shows the settings for customization


select each one then click the right arrow at the bottom to continue to the following screens that allow users to change the settings

Wireless Control

mostly has to do with the remote keyfob

I changed the wireless autolock to off, I keep getting locked out when im dusting my car off in the morning

I changed the wireless buzzer volume which is the alarm chirp to 7, much nicer now, I can actually hear it

I changed the trunk unlock to a double tap instead of a long press


-The security screen is blank so has no options to change


-The Warning Customization

I shut off the passenger side seatbelt warning, hopefully this will disable the stop the cell phone on the seat from setting off the annoying warning


– Air Conditioner

Not sure what these settings do in an FRS but I can see doing something with the BRZ climate controls



This has something to allow for detection of the vehicle. Not Sure what this does


– Door Lock

Wish it allowed you to turn on auto lock on the car but it is blank


– Illuminated Entry

Allows interior lighting changes


– Light Control
Used this to shut off the DRL’S


– Display
This page is blank


What other features does the tech stream have

Has some pretty cool live monitoring of values from the ECU.


Also has some ABS and TPMS but I believe its for viewing only


-Another cool diagnostic feature I played with is being able to toggle the dash lights on individually to test functionality.
