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 optimize 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 aluminum case, finned to ensure adequate cooling plus a beautiful carbon fiber 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.

Features:

  •  Significant increase in power and torque.
  •  Simple installation.
  •  Removable and undetectable.
  •  Constructed from Billet Aluminum.
  •  Anodized in signature MMR Gloss black.
  •  Engineered and hand-assembled in the UK.
  •  Calibrated in-house by MMR.
  •  Vehicle-specific loom and bracket.

Classy button shirt for dress up or casual occassions
Color: White, Size: XX-Large
I love the COOFANDY button down shirts!! They are soft, fit well, perfect length, maintain their color, and can be worn for casual or a fancy night out on the town. I’ve bought (4) of these so far.

Comfort
Color: Grayish Blue, Size: X-Large
The only thing I would change about these shirts and I've bought 9 now is the extra button they give you comes on the tag and not on the shirt like I'm used to so I lost the buttons. And I have a shirt that's missing a button now. But overall definitely a good shirt fits how you would expect. And is not cut overly short like a lot of dress shirts are nowadays
