HOW DOES CHIPWERKE PIGGYBACK MODULE WORK

The ChipWerke piggyback tuning module connects to the intake manifold and boost pressure sensors of the 2-liter turbocharged M274 engine in your Mercedes-Benz C300. Unlike permanent ECU tunes, ChipWerke only intercepts and optimizes the stock signals to modify boost pressure. It increases horsepower and torque without making any extensive and permanent changes, keeping OEM reliability and driveability intact.

ChipWerke works without overwriting the stock ECU, boosting power output while retaining OEM daily driveability and reliability. The ChipWerke’s tune can be adjusted with seven preset levels (-3 to +3) easily via the mobile app to optimize the power increase for your driving style, varying fuel quality, or altitude changes.

EASY PLUG-AND-PLAY INSTALL

The ChipWerke piggyback tuning module connects to the W205 C300’s boost pressure and intake manifold sensors underneath the engine bay cover and beneath the intercooler mount. It intercepts the factory wiring harness with top-quality plugs, so no wire splicing, cutting, drilling, or permanent modifications are required. The guide included in the package shows specific installation instructions for your vehicle.

The basic things to consider in all applications are as follows:

Turn off the engine and wait for it to cool down. Leave the driver’s door open for 15 minutes while keeping the keyfob at least 35 feet away from the car to ensure the ECU shuts down completely.
Locate where you want to mount the module. Make sure that it is away from the areas that tend to heat up relatively more.
Make sure the ChipWerke harness is not overly stretched and is protected against water.
Make sure that plugs are securely connected in place and that there are no unused plugs left.
