The MMR Performance S58 Power Control Module is the performance upgrade BMW enthusiasts have been waiting for. Tailored for the G80 M3, G81 M3 Touring, G82 M4, and G83 M4 Convertible, it adds a serious injection of power and torque without disturbing the balance and refinement that make these cars such a joy to drive. From the first throttle press, you’ll notice sharper response, stronger midrange pull, and a surge in peak output that makes both road driving and track sessions more exciting.
By optimizing boost pressure, ignition timing, and fuel delivery, the module ensures the S58 engine breathes at its best across the entire rev range. The result is faster acceleration and more urgency whenever you want it. Yet it remains smooth and composed, working hand-in-hand with the factory ECU to protect the engine and keep power delivery consistent.
Installation couldn’t be easier. This is a true plug-and-play unit—no cutting, splicing, or coding required. It slots straight in, can be fitted in minutes, and just as easily removed, returning your BMW to its stock settings. Because it leaves the factory ECU untouched, it’s a warranty-friendly solution that gives you flexibility and peace of mind.
The module is also built with the same care and quality MMR puts into every product. Advanced software algorithms adapt in real time, operating within factory safety tolerances to keep things reliable under hard use. The casing and connectors are engineered to handle heat and vibration, making it as tough as the car it’s designed for.
To suit different S58 models, dedicated versions are available:
- BMW G80 G81 G82 G83 M3 M4
- BMW G80 G81 G82 G83 M3CS M4CSL 551HP
Whichever version you choose, the outcome is the same—more power, sharper responses, and an even more engaging driving experience.
For BMW owners who want to tap into the full potential of their S58 without compromise, the MMR Performance Power Control Module is the perfect upgrade. It’s plug-and-play performance that makes your M3 or M4 feel alive in a way that stock power simply can’t match.
| G8X M3 / M4 (Standard) | +100 hp / +100 Nm | Solid upgrade with smooth gains |
| G8X CS / CSL | +110 hp / +100 Nm | Extra kick for the high-output versions |
UNLOCK UNPARALLELED POWER, EFFORTLESSLY
Maybe your G-Series M-Car can’t yet be tuned via conventional methods or you’re concerned about the warranty. Well, whatever the reason, not everyone is ready to tune their car through traditional methods; the MMR PCM could be your perfect tuning solution!
WHAT PCM DOES
PCM works by using our in-house developed calibration running on our standalone PCB, which communicates in parallel with the factory ECU. This communication route allows the PCM to safely optimise a variety of electronic sensor signals in real time, interfacing between the engine controls and its sensors.
With multiple channels such as charge air pressure, ignition and fuelling controlled by the PCM computer, the result is increased power and torque across the whole powerband of the engine.
We have carried tens of thousands of development miles of rigorous testing on our in-house dyno, on road and on track with numerous calibrations, across multiple cars and different hardware installations, allowing us to find the sweet spot for engine performance, drivability and safety.
EVERYTHING YOU NEED
With 12 months of detailed development, our PCM is more than a ‘tuning box’. The kit is complete, including a perfect fit wiring loom made especially for the selected vehicle.
COOLED BY FINS
The unit itself is housed in a stunning billet aluminium case, finned to ensure adequate cooling plus a beautiful carbon fibre mounting bracket to affix it securely in your engine bay.

ADDITIONAL INFORMATION:

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
