Oct 7, 2019
Full support for B58TU R4C9H6B5B is now added.
This ROM is found in cars with the B58TU engine (Supra, M340 and Z4 M40)
This means if your vehicle has been to the dealership and had a software update after 7 October 2019 then it is not supported at this time. With these new software updates, BMW keeps cycling the encryption which re locks the ECU with a method BM3 doesn’t have at the moment. However, they’re constantly working on these engine at the moment and with the mkV Supra sharing the platform and engine, we will continue to feel the love. Apparently the G29 M40i uses the same flash profiles as the mkV Supra. My ENET cable gets here Friday so I’ll find out for sure then. Got the VRSF downpipe and new NGK plugs today. K&N filter should be here tomorrow.
