This isnt all correct information.

Correct ... no such thing as an A91 LE. You have an A90 thats a LE and an A91 Edition .... 2 different things.

Incorrect ... A91's can be tuned depending on the ECU date. We've tuned multiple A91s that had an ECU date in May.
Yes exactly. The regular 2021's can be tuned after a bench unlock regardless of the date correct? A91's before 6/1/20 ecu date.

No, I believe any 2021 A90 or A91 with an ECU beyond June cannot be unlocked yet.

Ordered A91 edition Supra
No such thing as an A91 LE. 21 Supras can be unlocked after a bench unlock. The A91 special editions cannot, yet...

Depends on what you think LE stands for.
Launch Edition, or Limited Edition.
If you go by Limited Edition, the A91 is an LE. As is the Launch Edition obviously.

lol yea. i was referring to the fact that it's a limited edition since some people have the misconception that all 2021 models are A91s, which they aren't

A91 Supra
For any supra techs out there, how feasible would it be to take a and ecu with a build date before 6/20 and put it into a supra that has an ecu after 6/20?

I believe it is ANY B58 Supra with an ECU date after 6/1/20. It doesn't matter if it is an A90 or A91 cause there is no such thing really as an A91. The A91 is a gimmick for the 500 special black or Blue with the spoiler\stickers\stitching\keyholder.

So if you have the B58 Supra - A90 \ A91 \ A99 \ A100 \ A4000 or the newest A99999 - If the ECU date is after 6/1/2020 - You cannot be "unlocked".

I read today that the recent Audi ECU's haven't been cracked yet and they've been trying for years . Can anyone verify that?

They worked on the ECUs in the B9 S4/S5 for over 2 years before they were cracked. The B9 dropped in 2017 and the ECU wasn’t cracked until late 2019.

I have a 2019 S5 Sportback in the family and had a 2014 S4, so I have some familiarity with Audis.

Having said that I don’t know if the refreshed B9.5 ECUs are locked with protections similar to our B58 engines

Not possible. (That anyone has found yet.) - And i can promise that many have tried already.

I sent mine off out of curiosity to see if it was unlockable. I honestly expected the process to be unsuccessful as we have all discussed for weeks now. I heard back today that it is NOT unlockable. I have a 2021 A91 edition supra and my ECU build date is June 5th for reference.

Hopefully this is resolved soon

That’s tough, with time I am hopeful it can get cracked for all the newer ECUs :thumbsup:

I am curious if any of those piggyback options like JB+/ JB4 will work for you guys.

I've actually been following Spiguyver on youtube. He has a JB4 piggyback tune on his supra. I will be looking into that option over the next few months. The only issue is that I don't think you can clear CELs with JB4 tunes. I REALLY want to get a catless downpipe on this car, but it doesn't seem feasible at the moment.
