The ChipWerke piggyback tuning module is a plug-and-play tuning solution for the BMW M4 that connects to the two easy-to-reach sensors of the S55 3.0-liter engine. It works alongside and does not touch any settings of the factory ECU to improve boost pressure. ChipWerke’s Stage 1 tune delivers an extra 70 HP, and a custom Stage 2 is available upon request for your supporting bolt-on mods. ChipWerke is completely untraceable when removed and does not cause any diagnostic or reliability problems.

WHY CHOOSE CHIPWERKE PIGGYBACK MODULE

Significant Power Increase

ChipWerke’s Stage 1 delivers a healthy extra 70 HP. It unlocks faster acceleration and more linear power delivery across the whole rev band, while reducing turbo lag.

Untraceable Performance Mod

ChipWerke does not make changes to the stock ECU. It leaves no traces or diagnostic flags on the factory DME, so it is untraceable when removed.

Better Fuel Economy

Factory ECU remains unaltered, meaning you get a hassle-free performance upgrade while OEM safety measures continue to function as normal.

Extensive Customer Support

ChipWerke comes with two years of manufacturer’s warranty and extensive USA-based after-sales support for total peace of mind.

HOW DOES CHIPWERKE PIGGYBACK MODULE WORK

The ChipWerke piggyback tuning module connects to the factory wiring harness to alter the readings from the S55 engine’s 4-pin boost and 4-pin intake manifold sensors. 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 within factory parameters, 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 S55B30’s 4-pin boost pressure and intake manifold sensors underneath the engine bay cover. 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.
