    I saw references to Mini VCI and Techstream in a number of posts. It got me interested in getting a set as well.

    Just to get the terminologies right, Mini VCI is the USB/OBD2 cable right? Is it a specifically configured cable for Toyota? Or any generic USB/OBD2 cable would work?

    Techstream is the Toyota diagnostic software right? Is it a separate purchase or "download", or it comes with the Mini VCI cable? And if updateable, how to update to the current version? Or stuck with whatever version that comes with the cable?

    Also, is it finally 64-bit Windows compatible? Or still need to setup a virtual machine running 32-bit Windows?

    Thanks in advance for your inputs.

    VCI cable goes from USB to your car's OBD2 port The software I don't know about the virtual machine business but there are versions that run on most of windows My version is for Windows 7 on a CF-19 Panasonic dealer computer which I do not have a login for Toyota and so you will not get the automatic updates for your given car when you plug it in it will still try to warn you that you have old firmware on any of the myriad of computers usually it doesn't take too long to get this running on whatever you're trying to run it on it seems a laptop is best and older one or what have you speed will not make any difference whether you have the latest and greatest laptop or an older one you'll probably find the older one is best for this as it's going to be sitting in the sun and on top of a car and on the seat and generally that sort of thing you don't need the latest and greatest machine.

    Yeah, that's the thing, it seems Windows 7 is the latest version that is compatible with Techstream. If using newer Windows, then need to install VMware or VirtualBox just to run Windows 7.

    Feels like a clumsy setup: install Techstream on Windows 7 on VMware on Windows 11.

    I actually have an older laptop, let's see if it can be revived, very handy if it can run Windows 7 32-bit, will be prefect for this.

    Yes my CF19 Panasonic toughbook thingy is Windows 7 I do want to say it's 64 bit I think and it's on a my goodness equivalent of a core duo but none of that matters once tec stream is running. It overtakes the machine if you will text dream I don't think it's capable of running blazing fast like when you go from one window to the next and various things You're not going to make that go fast like you're playing a game or something like that and I don't think they would be a point to that you would go through things too quickly and miss stuff. Or something to that effect so I don't think blazing speed and whatnot is truly important so if you have to run it in VMware I guess so be it I guess running and VMware like running a windows emulator in Linux you know can slow down the computer but if the program you're running is already slow to boot and you're not looking for blazing speed then I guess my point is it pretty much doesn't matter. I would just rather have it on a junky old laptop that I don't care about it sitting in the sun for a minute or being on the hood of a car or sitting on seats and dashes possibly getting drops from knee height under the car floor or even the garage floor etc.

    I have two of the three you have in the original that came with the dealer computer that I have I mean I guess the newer one there could be faster I guess you mean faster between the car and the and the computer I don't see how that would make a whole lot of difference to be honest because text stream software is not fast by nature I mean but anyway yeah they're very cool

    Thanks for suggesting Openport, the original is quite dear, but the ones on Amazon looks more affordable. But that's just the interface right? I still need Techstream and the whole shebang of Windows 7 business?

    I think the confusion on 32-bit vs 64-bit Windows is not about Techstream, it should run fine on either architecture, as long as it is Windows 7. It is about the hardware driver, apparently some cables don't supply a 64-bit driver, so they are limited to 32-bit Windows 7, others do work on 64-bit Windows 7.

    fast even just doing the initial check or loading. I say the mini vci takes 30-45 seconds to click around and through, whereas open port would be 15-20 seconds. Like the hardware is better and can communicate with the Prius and computer faster.

    don't believe the hype... I never ran into an issue on windows 10 64bit.

    I just have a separate laptop with triple boot win 7, win 10, and ubuntu. the 7 32bt is needed for the software and hardware I use to make ecu changes so I put techstream and all else there

    If amazon has "affordable" versions of openport, then they are clones - knockoffs. Be aware. Don't know how they work.

    Please please please don't fall for that. The price on a real Openport 2.0 at Tactrix's web site has stayed $169 ever since I bought mine several years ago, even while other prices go up. That's hardly "quite dear" for such an article (the DrewTech one that Toyota endorses is close to $500) from a company that still exists, in the US, and actively develops and supports its product.

    If you see them significantly cheaper on amazon, there is no question you are looking at counterfeits.

    We have seen this movie before. The cheapest dongles you can buy that people use around here are the "XHorse" Mini VCI. I put "XHorse" in quotes because that was the original company, but no, people wouldn't spend the money on XHorse's Mini VCI when they could buy a counterfeit one for less, so the real XHorse was driven right out of their own business.

    Tactrix is one of the few we've got left still in business making their own product. If you want a dongle for less money, please buy somebody else's legit cheaper dongle, not a counterfeit Tactrix. Or buy a counterfeit Mini VCI, since that's the only kind of Mini VCI it's possible to buy anymore, so that damage is already done.

    no one has suggested any specific device, I will say... after going through two clones... DO NOT INSTALL THE LATEST VERSION OF OPEN PORT WHEN USING A CLONE, ONLY USE THE VERSION THAT CAME WTH THE DEVICE. Else, the one I purchased somewhere for a price good enough to go through two and buy another works fine for me.

    And please, unless you want us to reach the situation where there is no actual existing US company engineering affordable working dongles we can use, if you're going to buy an Openport, support the company that makes it and buy a real one, not a counterfeit.

    And if you want to buy a cheaper dongle, there are legit companies like VXDiag selling dongles that are cheaper, and there are other counterfeits like Mini VCI whose real makers already got killed off by people buying counterfeits, so that damage is already done and you aren't making it worse if you buy those.

    It's not just about supporting engineering and innovation, but also getting some level of after sales support. I wouldn't count on the Amazon seller to provide technical support in any way shape or form. I assume if there's an issue or unexpected error while using the original product, Tactrix would want to know and to do something about it in order to make improvements.

    By the way, is Openport universal? The eBay listing suggests it's vehicle specific.

    Yes this is where I have a problem The j2534 should be a j standard and not anybody's or manufacturers crap they have nothing to do with the j standard or shouldn't have and here in start the problems or perpetuate the problems everybody wants to own something or be part of it or some nonsense The j2534 should be Jay 2534 across the board the pin outs of the plug and everything should be the same. It doesn't matter anything else so how can these things all not work or semi work or whatever there shouldn't be any of that The standard is the standard the pin outs of the pin outs you can't just alter that because you had a good day at the office or whatever. To me that's a bunch of BS

    Only vehicle specific if you want to reflash ecu

    A USB cable is included with all models. Only specific older vehicles need a special reflash adapter. If you have one of the vehicles listed below, please use the drop down to select which plug you need added, or see our other listings.

    • OBD2 – Use for most modern OBD2 vehicles, inc:
      • Subaru BRZ, Forester, Baja, Legacy, or naturally aspirated Impreza models do not require a reflash adapter.
      • Mitsubishi EVO X, Ford Falcon BA BF FG, and more.
    • 01-02 Subaru WRX – Only required for 01-02 Subaru WRX
    • 03-04 Subaru WRX – Only required for 03-04 Subaru WRX
    • Mitsubishi – Only required for Evo 5 – Evo 9
    What OEM J2534 software does the Openport 2.0 work with?

    For more on what the J2534 standard does and doesn't specify, see this post (and maybe this one).

    J2534 is the specification of a Windows OS DLL and the functions in it that a software application (like Techstream) can call. The standard doesn't specify the dongle hardware, or how the DLL talks to the dongle hardware, as long as it does whatever it does and provides the right functions to the Windows app that is calling it.

    There are various hardware capabilities that the dongle may optionally have. J2534 specifies functions that the calling app can call to use those capabilities, and functions the app can call to find out which ones are and aren't available in this particular dongle.

    So if there's a dongle that doesn't support, say, K-line communications, and its J2534 DLL properly implements the "do you support K-line?" call and answers "no", then that is a J2534-compliant dongle, that doesn't happen to support that function. (If it were missing the "do you support K-line?" function, or if it answered "yes" when it doesn't, or "no" when it really does, then it would be noncompliant.)

    Tactrix grew out of the Mitsubishi / Subie tuner community originally, so the features supported by an Openport are chiefly the ones needed for those cars. Mine works pretty well for most things on my Gen 3 Prius, but it has some issues talking to TPMS. I've had more issues with it on a Gen 2, and I try to also bring a Mini VCI along if I'll be working on one of those.
