各位好
在小弟上一篇的關於z的文章裡
小弟有提到
新的supra電腦  目前不可能可以調
目前沒有任何已知的方法去調電腦
而在小弟發文地當時   因為只有一個美國知名店家的口述
所以我還持保留態度

但是現在這件事情應該算完全爆出來了
所以小弟決定發文分享



而且影響到的不只是supra
目前確定的   還有生產日期在2020年起碼六月25號以後的m4跟任何b48   b58引擎

而依據美國當地的改裝廠互相交流
他們不確定是甚麼時候開始
bosch改變了他們的安全系統
目前他們能夠追到最早的車子
是2020年六月25號生產的

也就是   從2020年六月25號生產的bmw  包括Supra
包括上一頁有人發的新款的m4
起碼目前為止   沒有任何方法可以改電腦

而ecutek預期(ecutek為知名改裝軟體)
這個無法改動電腦的現象
會很快的衍伸到其他的車廠  包括賓士等等

接下來會有一封公開信
這封公開信我們可以看到這些調電腦同業的絕望
基本上   目前為止所有的方法都無法破解電腦的安全系統
比如obd   bench   甚至把ecu打開插針的方式
都無法破解

他們甚至絕望到提醒同業
如果你看到有任何人宣稱能破解
除非有第三方獨立機構證實
不然先當他在畫唬爛



以下為ecutek的公開信

EcuTek Announcement:
Locked Bosch Bootloaders
As you may have seen some news, I would like to clarify the issues present on
newly manufactured Bosch MEVD and MG1 ECUs.

We've been aware of a situation brewing in Bosch ECUs initially identified on
BMW platforms but potentially affects all Bosch Tricore platforms that are
currently being manufactured. We were unsure of the extent of these changes
and how it would impact our business and yours, but we are starting to see
affected ECUs out in the wild now.

Bosch have updated the security on their most recently manufactured ECUs that
means that "bench unlocking" is no longer possible. This issue has been seen
on MEVD17 ecus in BMW M4s manufactured in July 2020, and in MG1S024 ECUs in
B48/B58 cars manufactured late June, July and August 2020. The exact data of
the switchover is unknown but the earliest date we have currently is 25th
June.

The result means for newly manufactured cars:
No OBD unlock
No Bench unlock
No bootpin unlock (that's right even opening the ECU to get direct access to
the processor does not help)

Not just BMW will be affected, expect to see this coming to the likes of
Mercedes etc.

There are no tuning products in existence that can support these new ECUs,
it's an industry wide problem, not just an Ecutek problem.
The latest cars will NOT tuneable using an ECU reflash from any company, with
any tool.

Older cars are unaffected and will continue to be tuneable
The changes are to the lowest level Bosch code, pre-programmed by Bosch at
point of manufacturer (it is not an update to the BMW or manufacturer
specific bootloader). So this is not something that can be easily recognised
by the ID of the BMW software version, Calibration ID or bootloader version,
our best guess is that it affects cars from June 2020 onwards. Our current
information is that this new Bosch bootloader is not field upgradeable, so
that means that existing ECUs with the older Bosch bootloader cannot be
updated to the locked version with something like a dealer reflash (this is
good!)

Our long term approach is we're looking for ways to allow programming of
these ECUs, but it's a significant challenge which we don't quite know the
scale of yet. We are working very hard to find a solution to this and nothing
is being ruled out as a potential fix.

In the short term we intend to add the manufacturing date fields to our query
tools to try and allow tuners to know with greater certainty what they are
dealing with. Our plans for tuning products are already changing as a result
of this development, and you may see our focus change subtly to support more
existing vehicles on other platforms. We will continue to increase the
breadth and depth of our tools and features to really push what is possible
in the OEM ECU marketplace.

I realise this is not what you want to hear, but this is the reality at the
moment. I would urge tuners across all marques, using all software tools to
plan ahead when it comes to their customers and treat them fairly and with
respect. None of us expected this to happen and we are all affected in one
way or another. Be wary of anyone that claims to have a solution to this
problem, until it's independently verified you should assume it's still an
issue. When a company does have a solution, this is good news for everyone,
as we will know it's not impossible to solve."



這是一個非常巨大的消息
我很驚訝整個車板只有我在關心這件事情的發展xddddddddddd

而小弟發這篇文章
主要是想知道
有沒有人能夠提供其他情報的?????
因為從這封公開信來說
不只是bmw
未來可能其他所有車廠都會在短時間內跟進
甚至可能已經跟進了    只是我們還不知道


而對車主來說   最重要的事情可能是
2020年六月後生產的bmw都有可能會是新型的ecu
也就是無法調整電腦
所以如果你現在正要購買
而你未來有意圖改裝
可能必須確定生產日期


以上
希望有板友能夠提供更詳細的消息
我真的很想知道是甚麼改變
讓美國前四大改bmw的tuner全都如此絕望
甚至還讓ecutek發了給同業的公開信????
