Recently purchased a Techstream version 10.XX.XX for a whopping $50 from Bulgaria
Its supposed to be 64x compatible instead of the dreaded 32bit. Windows XP
Working with Windows 10 ect..

What I can say is you can take a cheap MVCI cable ( given you have the correct drivers) and do the same thing as the $50 package.
I think the chips are even different in the inside. I took a little gander inside both and they are slightly different but both work the same. WIth his provided software.
You are pretty much paying for the software and it isnt working 100% or it was never working to begin with.
Running on Win10 now but its a 32bit program.
For all i know it could be a version 8 with the numbers changed to make it look like its a version 10.XX.XX

Expect partial functionality. Some things dont work like the generic OBDII
Will not do a ECU Reset without a code
Will not do a PCM or TCM reset

Will turn off DRL on 06 is250
Will monitor transmission oil temp along with some other monitors.
Will change some of the settings on the remote and lights some even said something about seat belts.
Will crash sometimes and does not like multi-graph views. ( i have a good computer with plenty of storage and ram)

Anyone else have any experiences?
