MERCEDES-BENZ CPC UPGRADE

Description

NOT ALL CPC UPGRADES ARE CREATED EQUAL!

Just like a tune, anyone can raise boost, raise torque limiters and dump fuel to make a vehicle feel fast. Is it reliable? Will the engine last? Will the vehicle perform? What are you really getting for your money? The AMR Performance CPC Upgrade for the 2019+ Mercedes-Benz supported vehicles is the most advanced CPC upgrade on the market. Our engineers spend time and test every intricate part of the software in real world conditions to ensure the upgrade we give you out performs competitors!

Our CPC upgrade is a direct drop–in replacement and addresses some key limiting factors such as speed limitation, boost limitation and torque limitation. With these factors in factory settings, your vehicle is not performing at its full potential. With the bonus of our engineers unlocking those key factors, we, in the AMR fashion take it one step further by increasing engine cooling, increasing intercooler cooling, 100% exhaust valve opening and much more giving your vehicle the edge of the competition’s upgrade!

What is a CPC? What is CPC on Mercedes?

The CPC Module, also known as the Central Powertrain Computer, was introduced as early as 2015 in the Mercedes-Benz turbo vehicles. Though added to these vehicles’ at an early date, Mercedes-Benz was starting to set the vehicles up for future limitations. In the 2019+ Mercedes-Benz (which includes pre-2019 E-Class) line-up, the CPC started to really shine as it limited not only vehicle speed, but also horsepower, torque, exhaust valves, HUD unit and in some vehicle’s even boost. Though the ECU can be “tuned” and enhanced, setting the ECU’s parameters to even max would not allow the engine to perform as the ECU was told, the CPC overrides the ECU giving the restrictions it was told to be given by the manufacturer. 

What does a CPC do? How does this effect aftermarket tuning the factory ECU?

This starts to make things a little trickier for the aftermarket tuning shops. These limitations and additional equipment added to the vehicles, in this case the CPC, are “new technology” in which standard generic tooling is not available making the ability to tune these vehicles properly and hit these high gains we are use to seeing in the past, difficult to say the least. Fortunately, AMR Performance, with our in-house engineers, are able to research and develop these “answers” in-house.

Can you just reprogram the one that is in the car?

Unfortunately, you can not. Reason for this is because Mercedes-Benz has what is called “One-Time-Programming” sector also known as OTP zone. This area is a one-time program area which CAN NOT be programmed over or re-written. This area is equipped with coding that checks the bootloader, application and calibration section of the CPC to prevent against tampering. If they all do not match to the required calculation, the vehicle will not operate. Anyone who tells you different, is just trying to selling you a myth. The most they will be able to do is change small variant coding changes (nothing to do with power or limiters) using Mercedes-Benz cloned tools that have ZERO effect to power, torque, boost, limiters, etc… whereas a full replacement from us will allow your vehicle to be fully unlocked to gain all benefits that once was not achievable.

For this unprogrammable reason, we start off with a new blank CPC module. This gives us the ability to write our own bootloader, application and calibration section. Giving us a blank canvas and allowing us a “no limit” style programming which our AMR Performance engineers love to do!
