VCI J2534 Cable Fit for Toyota TIS Techstream - Latest Version V17.00.020, Car Diagnostic Tool Cable OBD2 Firmware V1.4.8, Scanner Adapter Diagnostic Cable Scan Tool Support Win XP WIN7 WIN10 32/64bit

I have a 2017 flex fuel tundra for my work truck/mobile office. I have had a hard start issue since it hit 80k, mostly cold starts in winter at first, then it just deteriorated over time.1 aftermarket and 2 Toyota oem fuel pumps from the dealer and 100k later, the problem persists. I started asking more questions and researching the ecu giving faulty high alcohol density numbers, and I never ran e85…ever. So once the number value on my scan tool hits above 60% alcohol the truck would barely start and once it warmed up, it went away, until the motor got cold again. Techstream is needed to reset this awesome ecu issue every 3-5k, so I bought this cable, downloaded the software to reset the value, now I can fix my truck and the hard start every few months without the dealer hitting me for 2 hours of labor to do something that takes 30 seconds now. WATCH THE VIDEO several times, no sound, or pause and walkthrough the steps exactly as shown, it will work. You will still need a obd scan tool, to verify some repairs, this software is not all in one, yay Toyota. Great support for the product, you can even mess with factory settings such as seatbelt, seat memory settings and other small but neat adjustments for user customization.

Cable works fine. I got a spare key and TPMS replacements to work for my 2008 Toyota Matrix.The software and included instructions are junk. I tried to follow the directions but it didn’t work. Had to deal with pirated software that triggers antivirus only for it to fail to work once installed and connected.There’s a video tutorial on YouTube that has necessary links that did work. It involves setting up a virtual machine to run Windows XP.

I took away only one star because the instructions are poorly written, But given that there is also a video that you can watch to figure it out, I do think it is deserving of at least 4 stars. You can tell, even though they may not speak the same language, that they are trying to provide a good service.I was able to get the software going on my laptop. I will try to amend their instructions to be clearer.On step 4, if the driver installs correctly, you probably don't have to worry about this step. I probably spent too much time on this step... I think windows had installed the correct driver for me automatically and all was good to go, but I uninstalled it and followed the video to make sure. I probably didn't need to do that. If your driver installs correctly, in device manager under "Ports (COM & LPT)" you will see "USB Serial Port (COM [your COM number, mine was 5])" and under "Universal Serial Bus controllers" you will see "USB Serial Converter". If you see those, I believe your driver is installed correctly, and you should proceed to the next steps. Under "Other devices" you may see "M-VCI". If you see this, the driver is not installed; it shows this part of the setup procedure in the video around 7:09 so you can follow along on how to do that. In fact, the entire setup process is shown in the video if you have a question on anything. You can test that I'm right by unplugging your device and seeing that device manager updates to remove the entries I mentioned, and that it adds them back when you plug back in.On step 5, it says "[...] please click Cancel directly; select area and VIM as 1.4.8 and close." What you need to do here is in the Techstream software click "setup" then click "VIM select", look for "Interface setup:" and click the drop down. At this point, if you were following the steps, then you have the option for "MVCI Autokent-X64 - 1.4.8" for the 64 bit version windows. Click that and click "OK". That will complete step 5.On step 6, you need to copy the correct patch shortcut to your desktop, either the 32 or 64 bit version, depending on your system. This is how you will launch the software and connect to your vehicle. There is one hang-up here that is not mentioned in the instructions. Apparently, there is a new version of Techstream available, so a dialogue box opens when you click the patch. It says "update now" or "update later". Don't make the mistake I did of thinking that this step is supposed to update the software, and that you're supposed to click "update now". It will just open a browser window to update the software, which you can't do without being a dealership or paying for the software. What you want to click is "update later". After doing so, you can link your vehicle. You click the patch every time you want to connect to your vehicle. That's all there is to it.

Running Windows 11 64 bit edition. I'm pretty experienced when it comes to any software. Been in the IT field for 10 plus years. The video included with the software is very helpful but doesn't help because the laptop they are demonstrating on is in a foreign language. So the techstream software installed easily but the driver for the cable was a pain. I was getting a Vim error whenever I opened techstream regardless of what I told techstream what driver to use. The included paperwork was only helpful for the first 3 steps and then became very unclear.In order to get the driver to work with the cable I found a registry entry on a Toyota Tacoma thread. It's called mvci_x64. reg. After downloading and installing it my cables led turned green. Unfortunately the techstream version that came with the cable did not include the tpms option for my vehicle. I have a bad sensor that isn't reading on my front left wheel. This is the purpose on why I bought this product. I want to program new tpms sensors in the ecu. However I was able to downgrade to an 8.0 version that I found online and afterwards it showed a tpms option. I'm happy with everything that was provided but for a person that isn't to tech savvy it could lead to a lot of bad reviews. I hope this review helped someone. There is a lot of information online about the software. If you are looking to program a tpms sensor and it's not showing up on this version of techstream I suggest you downgrade to an older version.

I needed this to read and reset my alcohol fuel density level in my Sequoia but it falls just short of being able to do that. This scanner will read all the cars parameters except for the Engine and ECT, and those are the settings I need to access. After a week of research I found that I need either 2.0+ firmware or faster hardware, ie Mongoose or more expensive readers.The seller was really good with getting back to me.

Good part

El CD no funciona. Pero me comunique con ellos y con el link se pudo instalar sin problemas. Solo se debe desactivar La protección de virus del navegador y del equipo durante la descarga y la instalación

Not working, broken CD, waist of time!!! Considering it's not the best price, ordered it cuz I need it fast!
