The ChipWerke piggyback tuning module offers an alternative to a permanent ECU remap. It connects to the boost pressure sensor of the EA888 Gen 2 engine in your Audi A4 2.0T. ChipWerke recalibrates the restrictive factory sensor data to increase the turbo pressure. The modified signal improves the horsepower significantly. With ChipWerke Stage 1 tune, you’ll get 45 more HP over stock; with supporting bolt-on mods and custom Stage 2 tune, up to 35% increase is possible. ChipWerke improves power output throughout the RPM range and delivers better 0-60 times without compromising OEM drivability. It is untraceable and causes no TD1 or other diagnostic flag risks.

HOW DOES CHIPWERKE PIGGYBACK MODULE WORK

The ChipWerke piggyback tuning module is a safe and reversible alternative to permanent ECU tuning. It connects to the factory wiring harness to alter the readings from the 4-pin boost sensor of the EA888 Gen 2 engine. ChipWerke intercepts and optimizes the stock signals to modify boost pressure, increasing horsepower and torque.

It works within factory parameters and does not permanently alter the stock ECU, so ChipWerke boosts power output while retaining OEM reliability and daily driveability. 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 altitude changes.

EASY PLUG-AND-PLAY INSTALL

The ChipWerke piggyback tuning module connects to the Audi A4 2.0T’s 4-pin boost sensor at the front right of the EA888 engine compartment, directly on the pressure pipe. It intercepts the factory wiring harness with OEM-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.
