The way I read the Euro 5 regulation the OBD reg 1 (On-Board Diagnostics, Version 1) is in effect as they could not agree to the version 2 regs. These regs mean the bike has to monitor the emissions stuff constantly and throw a fault if there is an issue. Sounds like maybe a tangled web if you try to mess with it either by disabling the emissions or replace the pipe with a cat-less pipe. There are a lot of geniuses out there when it comes to altering a Busa but I think this is going to really be a puzzle. It will be interesting to see if the aftermarket guys jump right in with PC5's and pipes. That's the thing to watch. If pipes are available then someone knows how to hack it.We know (official announcement) that the IMU in gen3, is Bosch. A Taiwanese site is giving the ABS as Bosch (in Chinese) [ 重車檔案 2021 HAYABUSA 隼 ]. We also know that the most recent ECU by Bosch are locked [ New 2020/2021 BMW/MINI Models Not Tuneable | Locked Bosch ECU - MANHART Performance ] due to (probably) requirement that people do not override the Euro5 regulations as well as possibly "requirements for autonomous (or semi-autonomous such as the adaptative radar rumored to be coming to the new version of the HS2X) driving". This change (June 2020) has been very low key at Bosch and not announced officially.
Does anyone has information on the ECU brand in the gen3 ?
