In our latest dyno test we had the pleasure of tuning and testing this incredible 2024 BMW G87 M2. It goes without saying that it’s always great fun when we have a true ‘M’ car up on the rollers. As you can see, this was no different, as the G87 definitely has super unique styling.
Having spent considerable time with the S58 engine previously, we already know what an absolute masterpiece this engine is. We know it generates some pretty impressive numbers from stock, so know the tuning potential here. After an installation of our 3 Channel Pro Petrol chip tuning box, it was up on the rollers to see what the engine could achieve.
Now as you’ll have seen in some of our recent videos, the recurring issue that all 2021+ BMW drivers are facing, is the tuning limitations due to the locked ECU. This 2024 G87 M2 is no different and currently has no way to read or write the ECU data. Whilst ECU unlocking is now possible, the method in order to complete this, is still quite extensive. Firstly removing the physical ECU from the vehicle, then securely shipping this across to your chosen company, waiting for them to process the unlock, securely shipping it back, and then reinstalling back to the vehicle. Only then can you start to look at remap options. Obviously this is a risky and expensive service, especially when considering you may have many years of warranty remaining. This is why our tuning module offers the perfect solution, providing fantastic remap quality gains, without requiring a traditional ECU flash. This also has the added benefit of being traceless once removed for warranty purposes.

Firstly, we complete a stock run with the car at a completely stock level of mapping, to see what the car was running from factory. You can see from the dyno graph above that power and torque levels are elevated, showing 498hp with 650Nm of torque, instead of the 460hp and 550Nm which BMW quote. However this isn’t too surprising, when running 99RON fuel we would always expect to get a little bit more than those stock quoted figures.
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 498hp at stock, up to 607hp with the box. If you take a look at the dyno graph below you can see how we change that curve (dotted red and blue lines). We give real consistency here, bringing that extra power in as soon as possible, whilst holding it for as long as possible throughout the entire rev range, adding that +109hp at its peak, really transforming how it feels out on the road.

Torque also saw some impressive improvements. At stock the engine produced 650Nm and now 784Nm with the box. If you take another look at the graph (solid lines), you can really see where we have applied those gains. Again looking across that whole portion of the mid-range, you can really see exactly where its lifted, adding the +134Nm extra at its peak, delivering that increase exactly where it’s needed.
