My Experience With Techstream

What follows is pretty much the review I posted on Amazon for this item. I know many on this board have had success with it but it wasn't the case with me.

Seeing all of the reviews where people could change dozens of options on their vehicles I was excited to get this and delve into the options on my 2014 Tacoma 4WD TRD Sport, such as changing the door lock sequences. No such luck. I installed the software on an XP Virtual machine on my WIndows 7 Computer. The install went fine and the adaptor was recognized and the light was green on the cable.

Upon plugging it in and running the software though, the light turned red and the software offered very few options for customization. (Nothing for door locks or overhead lights.) I tried reinstalling everything and changing some settings in XP. Same result. Tried it with the truck running and with it off with the key on. Same result.

As the update program doesn't work for the adaptor (can't reach the website) I figured that maybe since the Techstream software provided was version 9.10.037 that the adaptor wasn't up to it without updating it so I tracked down version 8.00.034 of the Techstream software and installed it along with the drivers. Same result. Light turns red and offers few customization options.

It might be useful for the money for doing a Health Check, adding a key, or reading diagnostic codes, but for me, it's disappointing when I've read all that people have been able to do with it. I'm returning it. It may just be that my truck is a 2014. If anyone has any suggestions, I'd be glad to hear them. I tried a lot of things and I am somewhat computer savvy. (Been building my own since 1986.) Or let me know if you have a 2014 and experienced different results. I may try a different one or one from a different company, but I'm not hopeful as I believe they are all put together by the same "clone" company in China.

 

There isn't a lot of changeable options on any of the Tacoma Model Years. Toyota doesn't provide any other options regardless of the software or adapter you use. It is coded into the ECU that way.

Going from Version 9.10.037 Software to Version 8.00.034 would actually be a down grade.

 

Got the same chinese adaptor from AliExpress, it was cheaper - $17.75
Same results.
I registered new transponder key to immo ECU. Also I can turn off seat belt chimes and register TPMS sensors. No door lock options or units change (I wanted to chage miles to kilometers).
