Re: [分享] 改裝界要出大事了

有一個可能原因(不確定) Bosch E/E 架構改變，從分散式ECU演變成DCU (Domain Control Unit) Big Organizational Change at Bosch https://www.autobeatonline.com/articles/big-organizational-change-at-bosch ECU->DCU https://i.imgur.com/Se0FVYE.jpg 這也跟大概2~3年的相關資訊符合 https://i.imgur.com/TcZW6LJ.jpg https://i.imgur.com/1vAIjGF.jpg 簡單講，原本整車上百個ECU，逐步整合成幾個區塊的ECU 原本專責控制引擎的ECU未來整合進底盤DCU 底盤DCU同時負責動力(檔位)/轉向/煞車和ESC等底盤功能 但不是不能調，是Bosch不輕易開放給Aftermarket調 有趣的是在車用電子/ADAS/線控這塊 Bosch這種超大型Tier1供應商的話語權可是比某些中小型車廠還大 至於有辦法取得Bosch的Protocol，能夠改的廠商也不是沒有 不過主要不是做動力(性能)方面的調整 而是把車線控化(Drive-by-wire kit)，供ADAS和自駕相關研究 [Dataspeed] https://www.dataspeedinc.com/ [New Eagle] https://neweagle.net/engine-control/ 有的是外掛模組或破解方式啦，不過當然就不一定是車主負擔得起的改裝了 ※ 引述《whitestripe (light me up)》之銘言： : 各位好 : 在小弟上一篇的關於新款的NISSAN Z系列跑車的文章裡 : 小弟在結尾有提到 : 新的supra電腦 只要你的車子生產日期是在2020年七月以後的 : 目前不可能可以調 : 如果有哪家店家說他已經幫你調了 那家店不要再去了 : 而這件事情不只是影響到SUPRA : 目前已經確定 BMW最大宗那幾顆引擎都一樣中獎 : 目前沒有任何已知的方法 去調整新的BMW電腦 : 而在小弟發新款Z系列文的時候 因為只有一個美國知名店家的口述這件事情 : 所以我還持保留態度 : 只有在文章最下面當補充 : 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 : 也希望有大大能進一步補充最新進展跟消息 : 目前有確定中獎的 : 是生產日期在2020年起碼六月25號以後的BMW m4 還有任何b48 b58引擎 : 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(我猜M3一定也一樣) : 因為安全系統的大幅變動 : 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 這些改裝同業的絕望 : 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25號後生產的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???? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 42.72.139.49 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/car/M.1600911256.A.9E1.html
