The 2021 Supra uses the same EPS rack but with different software tuning and I personally felt that it was noticeably better on-center than the 2020 rack. So, tuners of the world, is this something that we could update with a flash tune? I know M3/M4 guys flash/code the GTS steering+diff+ESC updates but I wasn't sure if it could be done in the same fashion on the Supra.

Anybody know more about this than I do?

Very good point. It also seems that the rear diff software can be flashed over as well if the diff part no stays the same.

I would want this also :)

diff/rack and damper software update.
Shouldn’t Toyota give it to us as a free update?

Why would they give it free? You aren't entitled to it. Every manufacture makes minor changes every year. Are they expected to give you the update every year? Thats the cons of being a first adopter.

Tesla does OTA...
If they care about customer satisfaction, they could at the very least offer it to those who want. Even at a cost, people would entertain the idea of upgrading to improved __Guff, fill in the blanks__ (if they've done simulations/tests to confirm it works with MY20).
This is a special sports car for Toyota (at least for some execs). They could do such things, for brand loyalty.

I would definitely pay if it was offered. But to expect it free is just being a little entitled.

That's the model we've been fed with, all along. I'll give props again to Tesla and hopefully GM, Ford and FCA said they'd follow suit. If it's just a software update, and if cars are more computer based than ever, like iPhone/Android/Windows/etc. and we get continuous updates/improvements in those to masses, I don't see why we'd think we'd consider this as being "entitled", rather we're entitled to get improvements as they come..

Maybe I'm paranoid, but I feel like OTA from Tesla is a bit like them pulling the wool over the eyes. They are trying to treat their cars like software, where the driver doesn't necessarily "own" the car, but is licensed to drive it. I'm not saying that they are directly related, but I'm just concerned that other manufacturers that would do OTA updates might try to apply that model. While I'd love to get updates where possible, I would not want it at the cost of losing actual ownership of the car and my right to work on the car.

The only reason why I mentioned to get it for free is that is is simply software and no hardware changes AND there have been reports the early models have dangerous handling at the limit/high speed.
This was the only reason why Toyota had to update these items.

beging Toyota and safety driven I would indeed think/hope the software upgrades would be foc.

For bmw updates it has to be hooked up to ista so at the very least you would need to pay the labor. This I would be ok with.
