Welcome to MMR PCM; Power Control Module. A plug-and-play increase in power for F-Series M-Cars. Removable and undetectable.

Maybe your F-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 fueling 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.

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.

Really impressed!
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
I use this brand as my daily body sunscreen and love the smell, so I was tempted to buy this lip balm. I'm so glad I did! It smells great, and my absolute favorite thing about it is that it seems to last all day. I wear it with a light lip liner and my lips stay soft and moisturized after a long work day, 2 meals, etc. It does have a bad taste, but not nearly as bad as other brands I've tried. If you do the lip stick trick with your finger its unlikely to get in your mouth, unless you bite your lips. So its been a great protection against lip biting as well.

Funny after taste
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
Usually love Hawaiian Tropic products but this lip balm has a weird taste. The spf is good, if you don't mind the taste.

Hawaiian Tropics highly recommended for sensitive skin.
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
Love this product. This is my first summer using it. I was not disappointed. I have super sensitive skin, and can’t use most products. One thing I did notice was a few times I would get a small pimple or blackhead along the lip line. The dermatologist said it was clogged pores, but no reason not to continue using it. I have tried a few other brands and had more breakouts/ blackheads. So I keep going back to Hawaiian Tropics.
