Can't believe we're still waiting on the unlock. Especially with all the new M3's and M4's out there now unlockable as well. So ready to rip this piece of shit JB4 out and never look back.
For real I can’t believe this either looks like nobody is even trying to unlock the Supra ecuCan't believe we're still waiting on the unlock. Especially with all the new M3's and M4's out there now unlockable as well. So ready to rip this piece of shit JB4 out and never look back.
I thought all new released vehicles had the Bosch hardware lock. Did BMW revert back to a less encrypted ECU?Can't believe we're still waiting on the unlock. Especially with all the new M3's and M4's out there now unlockable as well. So ready to rip this piece of shit JB4 out and never look back.
Yea, I thought the same. Would be very odd if they did that.I thought all new released vehicles had the Bosch hardware lock. Did BMW revert back to a less encrypted ECU?

Last time I checked the BMW ECUs we’re still locked. There’s some click-bait out there that says the cars are tuned but they’re using JB4.Can't believe we're still waiting on the unlock.

Are you having problems with jb4 right now? Would you mind telling what they are? Because I’m thinking of getting it on my 21.Can't believe we're still waiting on the unlock.

~ Now $239.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.
~ Wow ... Dave at Burger Tuning was very kind and adjusted the purchase price back to $199 for me with an immediate $40 credit after purchase. Prior glitches have been remedied.~ JB Plus is Now $239.
I get a random CEL about once or twice a week, I clear it, and it's fine. I notice some weird down shifting jerkiness from 2nd to 1st. Overall yes the car still performs better than stock, but to me a JB4 is just a band-aid solution and we could be seeing much more impressive numbers with a real tune, not to mention I bought my car with the intention of putting a larger turbo in and other mods that can't be supported without a custom tune.Are you having problems with jb4 right now?

Thank you. I think I will enjoy the car stock for a while and make sure I don’t have any oil issues before modding it. It’s still pretty quick.I get a random CEL about once or twice a week, I clear it, and it's fine. I notice some weird down shifting jerkiness from 2nd to 1st.

That is the smartest thing to do.Thank you. I think I will enjoy the car stock for a while and make sure I don’t have any oil issues before modding it. It’s still pretty quick.
This is sort of right, but not exactly right. I'm a software engineer, I have been for 20 years. Hashing sort of works like this:Had a discussion about this with another IT colleague (works more on our security side) and although he did say that something could be "randomly" discovered, the likely hood of that happening without some type of "leak" from Bosch is HIGHLY unlikely. The level of encryption on that module is a minimum of 128 bit and would also require a "hash" (basically authentication code)from the ECU to enable access to the firmware.
We use something similar on our encrypted hard drives (laptops) and if an incorrect hash is used, the disk will effectively "brick" and all data will be basically lost. This method is used on higher level VPN's as well as VPN authentication tokens. Moral of the story is unless those details got leaked from Bosch.......you will keep waiting......the lack of effort from most tuners is not that they don't want to make money providing a tuning solution for the Supra, it's just that they know they are currently meeting their match.....not trying to be "debbie downer" here just hate seeing so many "hopefuls" on the forum......
