I'm looking to avail myself of the functionality of Techstream on my '03 Tundra and '02 sequoia.

Is anyone aware of what the differences are in the various versions of Techstream? It looks like they're not simply releasing newer versions and obsoleting the older ones, but keeping the older ones available.

Is there a product out there that anyone can recommend for viewing/editing some of the nuts and bolts of the computer settings in these 2 vehicles? One of the things I need to modify is the tire size since I'm currently traveling about 3.3% faster in my sequoia than the speedometer is reporting.

Thanks in advance for any insight you might be able to share.

I don't have any recommendation but I'd like to hear what you find. When I tried to get techstream a while back it required a 32 bit machine which I don't have. My neighbor keeps an old laptop just for this purpose so I used his instead. It was really helpful when I was debugging my evap code. If you find something that works with a modern laptop, let us know.

I just did a quick google for techstream and win10 x64 and see that there are lots of links for how to do it. I mustn't have researched much when I failed before since my neighbor had it working.... Not sure what version he has but it's got to be 10+ years old and was still pretty useful.
