Tuning solutions for your BMW
We recently had this awesome 2021 BMW 840i in for tuning and dyno testing. We’ve already conducted extensive development on these, so already know what the 3.0 B58 is capable of. After a quick installation of our 3 channel module, it was up on the rollers to see what gains had been made.
This G15 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.
Dyno Test Results:
POWER 358HP >>> 431HP
TORQUE 564Nm >>> 722Nm
Now delivering just over 430hp with an additional 158Nm 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.
