Tuning solutions for your ECU locked BMW
We recently had this awesome brand new 2025 BMW M240i xDrive in for an installation of our tuning module. We’ve conducted extensive development on the 3.0 B58, so already know it’s tuning capabilities. After a quick installation of our 3 channel module, the driver was back out, already experiencing those instant performance increases.
This G42 is also another example of a 2021+ BMW facing the tuning limitations due to the locked ECU, and currently has no way to read or write the ECU data. This means that while traditional remapping is impossible, our tuning module offers the perfect solution here, providing fantastic gains without requiring a traditional ECU flash. This has the added benefit of being traceless once removed for warranty purposes.
POWER 374HP >>> 430HP
TORQUE 500Nm >>> 630Nm
Now delivering 430hp with an additional 130Nm of torque, we have not only lifted those peak figures, but we really delve into where those gains are applied. Now pulling much harder right through the revs, we’ve significantly reduced turbo lag whilst providing much improved consistency across the entire rev range, really transforming how it now feels out on the road.
