LO400 Turbo Software

The most elegant ECU Tuning option available.

Driver Motorsport‘s LO400 Hybrid Turbo software is a complete solution. Here are a few reasons why:

  • Only a HPFP Upgrade is required, all other fueling components remain stock (Stock Injectors & Low Pressure Fuel Pump)
  • The ECU manages boost pressure and retains all OEM safeguards, no need for an external source of boost control (ex: Electronic Boost Controller).
  • All files are completely compatible with pump fuel, no need for Water/Methanol injection to reach our power figures.

Driver Motorsport‘s LO400 ECU file provide an easy upgrade path for any customer whose car has the typical Stage 2 bolt ons. They can simply bolt on an upgraded turbo, reflash their ECU and enjoy new found power.


The LO400 turbocharger is created using a genuine Borg Warner K04 fitted with enhancements to create a more efficient turbocharger. By building off of the stock turbocharger, reliability is increased.

The LO400 Turbo utilizes all genuine auxillary components such as the N75 valve, wastegate actuator and all other parts required to run this turbo. This improves reliability and consistency from turbo to turbo using hardware designed to last the life of your engine.

Driver Motorsport’s LO400 ECU file is only for use with the CDLx engines found in the Golf R, Audi S3, Audi TTS and Cupra R. These vehicles come equipped with an engine that has improvements to it’s fueling and rotating assembly that make it better equipped to support the additional airflow these turbos produce.
