Dennis, thanks for the heads up. I run the "MVCI Firmware Update Tool" program to check the firmware version without running Techstream. It reported the version number 1.4.1. If I unplug the cable, it shows N/A. When I hit the "Device Info" tab, the red light on the adapter would turn to green momentarily. I did some more reading on the SC forum and then followed a link over to PriusChat. My impression is for some vehicles, the version 2.0.4 may not fully work either. I ended up ordering a Tactrix Openport 2.0 adapter/cable directly from their store. Hopefully it will resolve my problem.

 

1.4.1 is the firmware version. I have 2 cables with that exact version that I have been using.

 

I got the Tactrix adapter today. Download the driver and installed it. Run the Techstream. In "Setup" tab, select Open port 2.0. It connected to vehicle without any problem; no problem for doing the Data List in the Tire Pressure Monitor System. Here came the test to update the ID. After entering 5 ID's, it came back right away with the message "ID update complete". What a difference! No more communication error. My "old" MVCI 1.4.1 adapter (bought 2 months ago) can do ECU data read, but not ECU data update. I highly recommend the Tactrix adapter if you experience the same problem that I have. According to ChampanF from PriusChat, the cheap clone adapter problem is because of bad quality control. Some people would have no problem, but some are not so lucky. Just for reference, the Techstream I tried is 10.30.029. I think newer version should work with this adapter.

 

 

I just got mine today and I can't get past the registration Key. Oh Boy.

 

Good to hear. I bought the same one from this seller last week. Should be arriving any day now.

I'll try to see if I can run the software on a Windows 10 64-bit. And to see if it works on a 2013 LS. I'll report back.

 

 

Did you read the install notes that came with the CD??

 

Yes, I did. It installed but, the registration key doesn't work.

 

Does this version have a .exe file on disk to copy to PC programs folder?

 

You need to unzip the main menu.exe file and the key.exe file and drop them into the tecstream bin file. It's not hard but a PIA. Make sure those two files are unzipped. The read Txt file will tell you which exe file it wants you to replace it may be one or it might be both. When you drop it in the TS bin file it will ask you if you want to replace the existing one. Say yes. After you have the TS loaded to your laptop and you plug in your cable to the laptop and you get the message that "your computer has not been modified" it is telling you that you are trying to run 32 bit firmware on a 64 bit machine. That means that you would need to go in and change the registry which is something 90 percent of folks do not know how to do and should not attempt. If it only asks for the main menu.exe file to be dropped in then then the Key file will show what the key code is. It will 46 or 47 numbers mostly 1's. When you get the message that you are showing plug in the key and hit OK not register your software. Hope this helps. You can use WinZip or Winrav (I think it is winrav) not sure to unzip the files.

Bought from this same seller for my 2nd set of MVCI + TIS. V13.00.022 could not work. V12.xx.xx works the same way as V10.30.029 but not fully functional. It can clear code, read ECU data but always have communication error when doing ECU data update/configuration. It will be interesting to know if it works on yours.

 

 

I contacted the seller and I'm going to return it for a refund. I'm done with this version.

 

This is where my problem is. The key, which shows the - and the rest of the numbers, the key is not taking. clicking OK doesn't do anything. Looks like the wrong Key here. Thanks for your help.
