HOW DOES CHIPWERKE PIGGYBACK MODULE WORK

The ChipWerke piggyback tuning module is a safe, plg-and-play, and reversible alternative to ECU tuning. It connects with OEM-style, quality connectors at the intake manifold boost sensor and turbo boost sensor of the EA211 engine in your Jetta 1.4T. ChipWerke intercepts and optimizes the stock signals to modify boost pressure, increasing horsepower and torque.

It works within the engine’s capacity and does not harm or strain components for extreme outputs, so ChipWerkeboosts power output while retaining OEM reliability. The mapping can be fine-tuned 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 climate conditions.

EASY PLUG-AND-PLAY INSTALL

The ChipWerke piggyback tuning module connects to the intake manifold and turbo boost pressure sensors of the 1.4-liter turbocharged EA211 engine. No drilling, wire splicing, or cutting is required.

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.
