A91 & Recent 2021 Impossible to Tune / ECU manufactured after 2020/6 is locked? [WARNING: NO POLITICS]

[Kiwi Greg]

I cant wait for the locked ECUs to finally be unlockable without shipping because I want to tune and do power mods just as well but it feels like 80% of you guys here act like this is the worst thing in the world and that you are only driving your supra at the drag strip.

I wouldn't say its the worst thing in the world, but if you have driven tuned VS non-tuned back to back you would start to understand why

Honestly I'd go buy a 2020 ECU if I knew 100% someone could code it to work properly in my vehicle without issues.

I believe that has been attempted and it didn't work.

I believe I read someone who attempted a different B58 ECU but not Supra for Supra. Not sure if you've seen one that was like exact ECU or not. I've heard people say it could be coded if it was the same vehicle, but no idea what kind of work that requires.

I still keep my hopes up, really hope there is a solution.

There will be eventually.

I'm running a megasquirt on my turbo e30... is anyone running full standalone or is it too risky at this point?

Think I know the answer already, but 06/06 ECU seems to be a no-go on tuning. Correct?

Seems to be varying statements on when it starts, seen 6/1, 6/21, 6/25, 7/1. Only way to be sure is to send it in.

6/1/2020 is the cut-off date AFAIK. I have not seen any post-6/1 ECU that is unlocked. I have a 7/1 build date and I am not even bothering to send it to anyone.

6/21 here...just sent it off to check, only cost me shipping, no big deal. better than assuming since it's never been "officially" confirmed as far as i'm concerned.

Thought @Marshall@ViscontiTuning confirmed the cutoff. Keep me posted on your journey here... I am pissed I missed the potential ECU cutoff date by 5 day lmao.

I THINK the confirmation is that they haven't seen one they could unlock from that date on so far. I never heard anyone say "confirmed by BMW or confirmed by Bosch".

^^^^^ Thank you kind sir!

Please enlighten me.

people keep saying the 21 are locked but can be unlocked by benching it? Or am I just retarded and it cannot be unlocked even if it was benched?

They're saying that 21 after June/July ECU production date can't be unlocked by benching. Prior to can. IE, you have a MY2021 with a 05/20 ECU then you're good. The ECU build date hardly ever matches the car build date. For instance, my car was built in August 2020, but the ECU is 6/21/20

Bench unlock is for almost all GR Supra whether '20 or '21. (I've heard a report that very early models didn't even needed bench unlocking but cannot confirm) However, ECU dated in June (still unclear but some time around 6/7/20) and after is hardware locked and cannot be unlocked at this point in time. As I understand, this is not limited to supra but for all cars using Bosch ECU. And dates varies for different cars.
