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).
