Tuning solutions for your ECU locked BMW
We recently had this awesome BMW M340i in for an installation of our tuning module. As you’ll have seen from several of our recent posts, the recurring issue that all 2021+ BMW drivers face, is the tuning limitations due to the locked ECU. This G20 M340i is no different and currently has no way to read or write the ECU data, without removing the physical ECU and shipping off to be unlocked. 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 387HP >>> 441HP
TORQUE 500Nm >>> 745NmDyno data pulled from our testing of the M340i, gave the figures above. Now delivering a much stronger 441hp with an extra 245Nm of peak torque from quoted figures, lifting it to 745Nm. We bring those gains in sooner, right down from those lower revs, whilst really opening up that midsection, giving improvements right

95 RON and 99 RON fuel is something that is debated heavily in the tuning world. It’s not always clear if there is a huge difference between them, meaning you could be missing out on certain benefits.
In its most simplest terms, RON is the octane rating which serves as an indicator of fuel stability. It’s a measure of the fuel's ability to resist "knocking" or pre-ignition within the engine. Knocking happens when the air-fuel mixture in the engine ignites too early or unevenly. This can reduce efficiency and, over time, potentially damage the engine. With higher octane rating fuel, the fuel is more resistant to this unwanted combustion.
In the video below, we test the real-world performance difference between 95 RON and 99 RON fuel on two BMW G20 330e models. One is running 95 RON, and the other 99 RON. Both are tested at stock, and then again once we have installed our 3 channel chip tuning module.
Looking at the stock dyno graph below, we can see that the 330e running 95 RON produces

Tuning solutions for your Abarth
As always, it’s great to see these hot hatches pull up at Bluespark HQ. This 595 was shortly back out on the road, after a quick installation of our Pro Petrol module, giving it that awesome lift in power and torque.
POWER 145HP >>> 172HP
TORQUE 206HP >>> 300NmNow delivering 172hp with an additional 94Nm 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.

Tuning solutions for your ECU locked BMW
We recently had this 2023 G20 BMW 330e in for an installation of our 3 channel pro petrol module. As you’ll have seen from several of our recent posts, the recurring issue that all 2021+ BMW drivers face, is the tuning limitations due to the locked ECU. This G20 330e is no different 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 292HP >>> 399HP
TORQUE 420Nm >>> 617NmDyno data pulled from a recent test of a similar G20 330e using the exact same engine set up, gave the figures above. Now delivering a much punchier 399hp with 617Nm of torque, bringing those gains in sooner right down from those lower revs, whilst really opening up that midsection, giving improvements right across

In our latest dyno test we had this incredible 2025 VW Golf R in for tuning and testing. We’ve already conducted extensive development on these, so already know what that 2.0 TSI engine is capable of. After quick installation of our 3 channel module, it was up on the rollers to see what gains had been made.
This MK8.5 Golf is also another example of the later VAG vehicles, which face 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 testing before and after shows healthy gains across the rev range, with a significant increase in power and torque, really transforming how it feels to drive.
Peak power was significantly increased, as we were able to lift it from 331hp at stock,
