Technical Features

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 Audi A3 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.
