Function of this part

The engine control module (ECM) is the electronic brain of the engine. It reads information from sensors and commands fuel delivery, timing, and other actuators to keep the engine running properly.

Why this part matters

Without a functioning ECM, the engine will not start or will run poorly. A correct, working ECM is essential for performance, diagnostics, emissions control, and protecting the engine from damage.

About the brand

Mack is known for building tough trucks and components for construction, vocational, and highway fleets that need reliable performance day after day.

Great valet tray!
Color: Brown
I needed something to help me keep my personal items organized, and saw this valet tray. I like how it looked and bought one. Then a bought a couple for my kids for Christmas presents, then a few more for around the house. We all like them because it feels good to be somewhat organized. I would definitely recommend them.

Total Game Changer for Your Desk Space!
Color: Black, Color: Black
I decided to finally foray into the desk mat space, and my only regret is not doing this sooner. This particular mat is not only an instant upgrade, visually, for my desk, but also gives me a convenient place to tuck away those couple papers/cards I always need to have within reach. It goes without saying, my favorite part of this is the high quality wireless charging piece. Aside from eliminating an extra cord, it helps minimize the clutter and lets me charge my phone AND AirPods simultaneously. This is the first of many I will be purchasing, as it is the PERFECT gift for anyone with a desk.

Honestly, this is pretty nice!
Color: Black, Color: Black
At first I was a little disappointed in the design of this device because the mat and the charger are two separate pieces; but the magnet that is connecting them together is pretty strong, so I ended up not minding it. The magnet in the charger is pretty strong too, though, so the whole thing tends to lift up when you pick up your phone - this is my first MagSafe charger, so perhaps that is standard with these, I wouldn't know. As you can see in the picture, this isn't your standard mouse pad. It's leather on one side and felt on the other (you can pick which side you want to face up, which is a nice design feature, I suppose). It's smooth and wipes off easily but really collects fingerprints and hairs. It's also a good size. Not too big, not too small. I was a little worried because it's smaller than my older mousepad but I haven't suffered for it. I may even prefer this smaller size if I'm being honest. I'm not sure if I like the feeling of the leather side against my arm/wrist, though. The mouse has no problem reading it but it's just not very soft. I do notoriously dislike change though so maybe that's just a me problem LOL. All in all I'm happy with this and would suggest it!
