Your Top 7 Mercedes Tuning Questions Answered 

You know you want your Mercedes Benz to perform at its best, but as you’re doing your research, you might not know exactly where to start. Never fear, here are some of the top questions we encounter when working with our clients on Mercedes Tuning.

  1. What exactly do you so with Mercedes tuning?

No matter what model your Mercedes, there’s this device called the ECU or ECM under the hood of your car that we’ll carefully remove and run through special diagnostics to determine what we can do to improve engine performance. By remapping your ECU ECM, we can increase things such as boost pressure, change your spark advance timing and calibrate a new torque curve.

 What the heck is an ECU?

It’s your electronic control unit, also known as an engine control module (ECM), an embedded system that controls your car’s engine. This is the technology that helps your engine run. And by making strategic tweaks to your Mercedes Tuning file, we can make your engine run to its fullest potential.

  1. What do you mean when you say that my Mercedes is depowered?

Car manufacturers are able to tweak engine power more easily through the ECU ECM. Especially when a new series comes out, the manufacturer is thinking long term, and wants to be able to increase performance specs each year without drastically changing the engine. This means, especially if have an older model, your engine has likely been depowered. The exciting thing about this is that we can make your car run better, without expensive upgrades. The power is there, it just needs to be set free with Mercedes Tuning.
