~ Yours is locked. The ecu would need to be stamped 5/20 or earlier.My apologies if this is clearly articulated here, but over the almost 50 pages of posts, Iām not quite sure. What is the cutoff date for the ECU (not build date of the car) for tunable or not? I have a July build and a 6-27-2020 ECU.

But many thanks for the fast reply.
You missed the cutoff by 27 days. The second option you have is a JB4 piggy back system.My apologies if this is clearly articulated here, but over the almost 50 pages of posts, Iām not quite sure.

Maybe I can scratch of the date, write in May, and see if that works.You missed the cutoff by 27 days. The second option you have is a JB4 piggy back system.

ECU build date cutoff still applies 05/31/2020. The DME unlock is required first for a certain range of tunable cars. The first 2020 Supras came with DME unlocked from the factory.Might be a glimmer of light for A91 & Recent 2021 Supra owners.
About 6:35 into the video - seems like it could be tuned.
Yes bump, can you expand? How is power delivery? Is it smooth? Choppy? Waste of time while waiting for tunability or totally worth it?Im currently running an JB4 but having some slight issues here and there.
Its a good alternative as of now.
Get a JB4. Its probably going to be awhile before it gets cracked.Any updates to this? Kinda itching to add power now. lol
I have a 2021 and just did the JB+ and while its obviously not going to be anywhere near as good as a real tune or even JB4, I can tell you 100% for $200 it is a tremendous value. Definitely wakes up the car.I have a locked 2021 and I am planning on doing a JB+ (not JB4) on my car and keeping it stock until the warranty is almost over...hopefully by then the ECU will be crackable and any issues with the engine will have been identified and be able to be fixed via warranty/recall/TSB.

That's really all I'm looking for until a true ECU Tune - I would do an ECU Tune along with downpipe, etc.I have a 2021 and just did the JB+ and while its obviously not going to be anywhere near as good as a real tune or even JB4, I can tell you 100% for $200 it is a tremendous value.
