Remap Of Mercedes CLA 45 AMG

Remap Of Mercedes CLA 45 AMG

A brief review of AMG CLA 45 (C117)

This beautiful looking thing is a CLA 45  which is basically the same as A45, but it’s a bit more grown up. In fact, it’s for people who don't want to buy a racer hatchback but still want all that fun and performance. Lets kick off this review by talking about the engine because this is what makes the CLA 45 so special. Nowadays, the third generation of CLA(C119) is the most powerful 2.0 litre four cylinder engine in a production vehicle. With 421 horsepower and 500 newton metres of torque besides the turbocharger, that’s why it can produce all that power. capable of accelerating from 0 to 100 kilometres in 3.9 seconds which is so fast for a little four cylinder engine. This car is equipped with 4matic plus which means it drives all four wheels via an 8 speed dual clutch automatic gearbox. So whenever you see a 4matic plus you should know that it is a very special system for very special AMG’s. This one has electromechanical clutch packs to send exactly how much power this car needs to exactly which wheel and it theoretically sends up to %100 of the available torque to the rear wheels so it can be a %100 rear wheel drive. Furthermore, the way its traction control system works and the way this whole car feels, if you put it into ESP SPORT, it lets you slide out so much more than a normal car. 


What goes wrong with CLA 45  ?

  • Noises of rattling, buzzing, and squealing from around six separate spots inside the vehicle is the most frustrating issue
  • Poor shifting/clutch engagement and lurching at low speeds. It appears to be rough.
  • Unnecessarily harsh ride. This, in my perspective, exacerbates the rattling. A technician said.


AMG CLA 45 Engine and ECU

The newly developed AMG 2.0-liter high-tech engine, which is the most powerful mass-produced 4-cylinder engine with twin scroll turbo scharger, follows the legacy of its predecessor. The Mercedes-AMG CLA 45 4MATIC is powered by a 4-cylinder high-tech engine(M133 DE20AL) with 355 horsepower and 450 Nm that relesed 2013~2015 and managed by ECU Bosch MED17.7.2 .
