IE's motorsport-inspired software completely retunes the ECU calibration on your 2.0T FSI (EA113) factory K04 turbo engine while retaining factory comfort and reliability. using industry-leading tuning technology and decades of race engine tuning experience, IE engineers completely reverse engineer the factory mapping and customize it to maximize performance for the enthusiast driver for the street and track. Your new software tune is easily uploaded to your factory installed ECU (engine control module) without touching a wrench in your own driveway. Multiple tunes are available to match your stock or installed aftermarket hardware.

IE Stage 2 ECU Tune

For customers looking to maximize the performance of the stock engine and turbo setups with bolt-on hardware, IE Stage 2 software fine-tunes the ECU calibration to match installed aftermarket hardware.  Stage 2 results deliver massive power gains across the powerband, fully realizing the engine and stock turbocharger potential. Includes 91, 93, and 100 octane switching.

Stage 2 required & recommended hardware

• Performance Downpipe (required)
• IE High Pressure Fuel Pump Upgrade (required)
• IE DSG Transmission tune (required for TTS)
• IE Cold Air Intake (recommended)
• IE Intercooler (highly recommended)
• Performance clutch upgrade (highly recommended)

Optional Features

IE Stage 2 Light

IE Stage 2 light software is for customers who have installed a downpipe required for Stage 2 but have yet to install an IE High Pressure Fuel Pump (HPFP). Installing a performance downpipe while running a stock or Stage 1 ECU tune can result in over-boost conditions, check engine lights, or "Limp Mode". Stage 2 light will increase power levels taking advantage of the downpipe change while keeping safe fuel operating conditions. This will increase power greatly over Stage 1, but not to our full IE Stage 2 High Torque file. Stage 2 light is included with the purchase of a Stage 2 file, once an upgraded HPFP is added, the user may upgrade to IE Stage 2 at any time at no additional cost.

Easy At-Home Tune Install

Required to flash your new tune, IE's DIY Flash Tool allows you to quickly upload your tune from your own garage or driveway. This OBD plug-in device is easy to use with a Windows-powered laptop and WiFi connection. Your new tool also includes the abilities to switch between multiple octane files (available separately), reading and clearing diagnostic codes, upgrading Stages, or flashing back to stock.  

Upgrading Tunes

Already have an IE Stage 1 tune and IE DIY Flash Tool? Upgrading to Stage 2 or beyond is easy! You only pay the difference in cost between the files with no additional or hidden fees. Once the required supporting hardware is installed, simply plug in your DIY Flash Tool and follow the instructions on your screen to purchase and flash the upgrade file.

Dynometer Optimized

After completely reverse engineering the factory ECU, our engineers use our in-house Dynapack DP42 dynamometer to perform repeated runs to test each change that is made to the software and confirm drivability in any situation. This ensures IE performance software delivers massive horsepower and torque increases across the entire powerband. Using our in-house dyno and advanced tuning tools, IE engineers have fully optimized every aspect of the factory ECU mapping on many different vehicles. This produces a tune that retains all factory like driving and safety protocols when needed, and an intense surge of power when you want it.

Removed Speed Limiter

The factory ECU speed limiter has been removed to make sure the increased power and torque can be used to its full potential on straightaways and drag strips.

Increased Rev Limit

With the significant power increase, the rev limiter is also increased to allow a wider powerband on all IE files. By increasing the rev limit, you gain a perfect match for the increased performance available from your new IE performance software tune.

Improved Throttle Response

To further increase the responsive feel of the car, IE engineers have carefully adjusted the throttle sensitivity. This offers a more connected feeling to your car with plenty of power available right beneath your foot.

Optimized Fueling

All IE tunes have been adjusted to run as economically as possible, dialing in air/fuel ratios to exactly where they need to be. With an IE performance ECU flash, it is common to see increased fuel economy under cruising and part-throttle driving.
