For all of you that have a Mercedes CGI turbocharged engine in your late-model Mercedes – engine codes M270, M271EVO and M274 – Carlsson has announced that it now offers CB kits to help bump power by up to 28 percent.

The base CB kit is an adapter plug that goes between the vehicle wiring harnesses and the factory ECU. This little nugget of joy communicates with the various electronic systems within your Benz, assessing the driving situation and conditions, and making adjustments to optimize power.

There’s no need to worry about reliability when you install this kit, as it includes safety checks that help prevent damage that some other tuning kits may cause. First, the CB kit waits for the engine oil temperature to reach 50 degrees Celsius (122 degrees Fahrenheit) before the performance boosts activate. Secondly, the CB kit closely monitors the limits of the CGI engine (oil temperature, coolant temperature, etc.) and drops the ECU to its normal performance if these limits are reached.

This kit’s improvements range from a 24-horsepower gain in the A 180 and B 180 to a 42-horsepower gain in the A 250 and B 250.

For those that want some extra power from the M271EVO engine lineup, the CBS kit is available too, which adds a larger and freer-flowing intercooler to the base CB kit. The power increases from the CBS kit range from 35 horsepower in the C 250, E 250 and SLK 250 to 45 horsepower in the C 180.

When you purchase this kit, Carlsson further shows its dedication to keeping your Benz running by taking over the manufacturer’s drivetrain warranty for two years or 100,000 km (62,137 miles).

Carlsson Releases C-Tronic CB Kits For Mercedes-Benz Four-Cylinder CGI Engines
- image 507528

Performance-Plus for Mercedes-Benz four-cylinder engines: Up to 28 percent more performance with Carlsson C-Tronic CB kits

  • Adaptor plug with integrated control unit
  • Plug & Drive design for easy installation
  • Up to 28% performance increase with TÜV approval

Fast and easy installation, maximum performance and reliability are the principles underpinning the new Carlsson C-Tronic CB performance kit. Capable of extracting up to 28 percent more power from the four-cylinder CGI engines, these "Plug & Drive" units can be installed in under five minutes.

Each Carlsson CB kit comes as an adaptor plug with integrated control unit, enabling the unit to be mounted between the factory ECU and its input wiring harness. Communicating continuously with the vehicle’s electronic system, the CB unit optimizes performance by assessing the current driving situation, then adjusting parameters and variables to match its pre-determined performance maps.

To maintain full engine protection, the Carlsson mapping will not allow the enhanced performance to be used until the engine oil temperature reaches 50 degrees Celsius.

At the other end of the scale, should the oil temperature or other high load parameters reach pre-ordained limits, the CB unit automatically reverts to the standard ECU’s protection settings. Thus, while the Carlsson CB kits guarantee maximum power output under ideal conditions, they also ensure that the factory mechanical safety limits are never exceeded.

Carlsson offers the C-tronic CB kits as CB and CBS variants for the Mercedes-Benz four-cylinder turbocharged M271EVO, M274 and M270 engine family with full German TÜV approval, and the three-year Carlsson component warranty. In addition, Carlsson takes over the manufacturer’s warranty on the engine, gearbox and drivetrain for up to two years or 100.000Km, from date of first registration.

To keep the intake charge temperatures low for optimum performance, the Carlsson CBS Kit comes with a larger, more efficient intercooler unit.

Owners can also rest assured that in addition to being covered by German TÜV approval, vehicles upgraded with the Carlsson CB kits also continue to meet Euro 5 emissions standards.
