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.

READ THIS AND CHANGE YOUR LIFE FOR THE BETTER NOW!!!
33% of Americans are verging on type 2 diabetes and do not know it. This should make you run to get this book! Following Glucose goddess on Instagram and got her book as well. It is easy to read, with fun illustrations by the author. She has truly helped me so much with my insulin resistance and managing my glucose spikes. "Lifestyle optimization" is an essential for everyone. Why wait until you are diagnosed? These hacks are simple, fun, and super easy. Her audiobook is also out now and is read by the author!! Which is awesome. What makes this book even MORE useful though, is if you invest in a continuous glucose monitor (CGM) and have the app. I had the Freestyle Libre sensor. Each sensor lasts 2 weeks on the skin and logs your real-time glucose levels 24/7. Way better than doing the old fashioned painful and wasteful lancet and test strips. Although you can verify your CGM occasionally using the lancet, and see how accurate the CGM is. You can have a CGM prescription written for you if you INSIST at your nurse practitioner's. (NPs are WAY more open to this kind of experimentation and self-monitoring...I got the rebuff from the doctor, HA!) What is so sad is that the healthcare system is so broken that insurance will NOT cover a CGM UNTIL you have full-blown type 2 diabetes and are dependent on exogenous insulin delivery. OR if you are a type 1 diabetic and born without the ability to process glucose. Sad huh? The FDA wants you sick, fat, ugly, and miserable. We are MUCH better desperate customers then...willing and eager to take any pills to solve the problems! Let's not be proactive and encourage the PATIENT to take measures against type 2 diabetes, right? So there are MANY benefits of managing glucose. Fairly effortless weight loss actually. In this book she dives into nutrition science and the biochemistry of different sugars as well. She has so much credibility and science-driven data backed up by her own personal journey as well as many peer-reviewed articles. Thank you Jessie!

Really Good Book & Inspired Me to Take Action
Format: Hardcover
After I finished reading the book, I asked my doctor for a Continuous Glucose Monitor. For two weeks, I reduced my carb & sugar intake & was able to keep my glucose in the "steady" range. Then, I ate an oatmeal cookie without pre-eating any fiber or protein. BIG SPIKE! One cookie sent my glucose soaring. I can't even imagine what happens to my body when I eat 1/2 pound of candy. This book was written in a very understandable way & it inspired me to start tracking my glucose levels. I recommend reading this book. And there is definitely something about seeing the effect on your body when you eat sugar by using a CGM. It's an almost immediate visual telling you that you're inflicting damage on yourself. When you don't see it, you can pretend it's not really happening. When I saw that spike, I imagined my poor body trying to release all that insulin to remove sugar from my blood.

Great Book to Understand How Diet Impacts Blook Sugar and Health
Format: Hardcover
Life changing book that helped me understand how sugar and processed foods impacted my health. I verified the tips in this book with my own blood glucose monitor. The tips that she shared helped me reduce my glucose spikes and helped me enjoy a little snack from time to time.

Quality is as good if not better than the Brand name Water picks. This flosser is super powerful and gets the spots a toothbrush can’t! I would recommend it to anyone.
