POWER CONTROL MODULE

INTRODUCING MMR PCM.

A plug and play increase in power for G-Series M-Cars. Removable and undetectable.

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!

PCM works on a standalone PCB, which communicates with the factory ECU. Developed by MMR's own in-house calibration experts over the past 12 months, it allows the vehicle to safely increase power and torque levels throughout the entire rev range.

Easily installed, and easily removed at any time without a trace.

Install at home, yourself.

PCM has a simple installation, providing you have a basic level of mechanical knowledge. The PCM unit sits in the engine bay using the provided carbon fibre mount and hardware, while the wiring loom is plugged into existing sensors in the engine.

 

Or for full peace of mind, all of our approved PCM dealers around the world can also install this for you, subject to labour charges.

Developed in-house.

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.

PCM vs ECU Calibration.

We're completely honest about this, the PCM calibration is not as sophisticated as a full ECU calibration.

 

To keep the car smooth, safe and reliable, PCM's power levels have to be kept lower than traditional ECU calibrations.

 

But of course, you'll love the power boost you get from PCM, combined with the drivability and efficiency gains.

PCM FAQ

  • What is PCM?
    PCM is MMR's latest tuning solution suitable for the latest G-Series M-cars such as the G87 M2, G80 M3, G81 M3 Touring and G82 M4; for both xDrive and RWD variants. PCM stands for ‘Power Control Module’ and is our way of adding more power and torque to your M-Car car, improving drivability and overall enjoyment out of the chassis. Expect to see exceptional power gains across both the high and low-output variants. More specific power and torque gains can be found on the individual product pages. Although some of these cars can now be calibrated using traditional methods, it comes at a premium and risk to warranty. 12 months of detailed development and testing in all environments has gone into PCM. It's easily installed, and removable without trace at any time. As we have developed PCM specifically for G-Series vehicles, the fitting and installation kit has been designed with the usual MMR attention to detail; rather than a generic kit that is held in place with tie-wraps and coiled-up lengths of wiring! The PCM itself is housed in a stunning billet aluminium case, finned to ensure effective cooling plus a beautiful carbon fibre mounting bracket to locate it securely in the engine bay. The full install kit includes a wiring loom made to the perfect length for the M-Cars cars.

  • Where to buy PCM?
    Any MMR Dealer anywhere in the world can supply your PCM unit. You can also purchase a PCM directly from MMR. To search our dealer map and to identify our approved MMR dealer, click the link below. With our dealer network's extensive knowledge, they will be happy to support and advise you on anything PCM and hardware related.
  • What PCM do I need?
    PCM has been carefully, and exclusively developed for specific G-Series M-Cars. For each engine type, a specific PCM unit is available. PCM does not work on any other car/engine type other than those listed.
  • Can I install PCM at home?
    PCM has a simple installation, providing there is a basic level of mechanical knowledge and hand tools available. The PCM unit sits in the engine bay, using the provided carbon fibre mount and hardware. While the wiring loom is plugged into existing sensors found at the top of the engine. For maximum peace of mind, our global network of approved dealers can also supply and install PCM for you, subject to their labour charges. PCM is also completely removable, with no changes to be made to the hardware or software of the original car. We also include a PCM blanking unit, which plugs into the existing wiring loom and removes the PCM calibration, without having to remove any of the installed hardware should you ever wish to temporarily disable it.
  • Is PCM removable?
    Yes absolutely. One of the best aspects of PCM is that it is completely removable, with no changes, cutting or drilling needed to be made to the hardware or software of the original car. We also include a PCM blanking unit, which plugs into the existing wiring loom and removes the PCM calibration, without having to remove any of the installed hardware.
  • Can I install the PCM with existing modifications?
    Yes, definitely. PCM has been developed with our performance hardware in mind from the start of our design process. Whilst PCM has been developed to work perfectly on an unmodified stock car, it has also been calibrated to self-adapt to take full advantage of any MMR hardware upgrades. The PCM will support hardware upgrades to your intake system in line with traditional Stage 1 modifications. Of course we've completed all of the PCM development in conjunction with our own class-leading hardware parts. But if you've chosen other-brand hardware, as long as it's still decent quality, PCM will still give power gains.
  • Can I install PCM 'on top of' a tuned ECU Calibration?
    PCM has been carefully developed to work with, and enhance, the ECU's factory calibration only. While it could be installed with a tuned ECU calibration, we strongly recommend against doing this, as the values in the PCM calibration have been set and developed in-house to work alongside the factory calibration. Running the PCM in conjunction with a tuned calibration would push the engine's parameters beyond its proven and tested limits. Therefore we cannot guarantee any results if a PCM unit is installed alongside any independently tuned calibration.
  • What fuel grade can I use?
    PCM has been designed to work with different fuel grades around the world, just like factory calibration does. Meaning it's perfectly safe, whatever grade of fuel you put in your tank. However, using a lower fuel grade will result in less power, meaning that a premium octane fuel is always advised for best performance and long-term engine health.
  • Talk to me about warranty!
    It's very clear - any tuning modification on your vehicle can invalidate your manufacturer's engine & powertrain warranty. So if your dealer sees the PCM fitted, then they'd be entitled to reject a warranty claim on the engine or drivetrain. Of course, PCM is fully removable. With it removed, the car is returned to true stock, but whilst PCM leaves minimal trace to the ECU, it's important to understand that there is no guarantee that this product is warranty safe and is installed at the customers’ own risk.
