It's good they have found a way to unlock them. Makes me wonder what Toyota is trying to protect or if the trans/certain other points are unable to be fully controlled

It likely has little to do with Toyota and more to do with Bosch trying to protect their intellectual property and fixing a security flaw that has existed for a year. Bosch is fairly active in trying to secure their computer technology.

Maybe they were talking about A91s like the one in this video making 700+HP



"Here at Titan, we were able to unlock a couple of A91s already. Unleashing all the power that these 2021 Supras have. We got this A91 to push over 700+ HP with a 670 torque all boost! No nitrous. Check it out!"

i dont think people know A90 vs A91 means nothing. A91 is just the 1000 unit special edition. ALL others are still A90 supras. So A90 or A91 doesn't matter. its the build date that's all that matters in terms of the new Bosch locked ECU or the others. and there are some A91s with tna early build date

wow a race shop like Titan can't even differentiate between an A90 and A91... And 700+HP ain't nothing new for this platform

Its confusing. And the marketing teams dont always work with tuners and arent in the know of all terminology. It happens all of the time. It didn't help that toyota at one point referenced 2021 as A91's...
