  • How do I install Integrated Engineering ECU / TCU tunes on my VW / Audi?

    In order to install the tunes, you will need to also purchase the Integrated Engineering POWERlink Flash Cable, which you can find HERE.  You will be able to flash your engine and/or transmission with the software that is included with your POWERlink Flash Cable.


VW & Audi 1.8T Gen 3 engines are controlled by an advanced Engine Control Unit (ECU).  This powerful computer is loaded with complicated maps and routines from factory to optimize vehicle efficiency over performance.  Tons of available power is left on the table and the calibration is not written to take advantage of aftermarket power adders such as cold air intakes, intercoolers, donwpipes and more.

IE's ECU upgrades replace these boring stock files with Motorsport ready tunes developed from extensive engineering.  Our leading ECU calibrators completely reverse-engineer the factory mapping and re-write new calibrations for ultimate performance without sacrificing factory comfort and reliability.  Each performance stage undergoes thousands of dyno tests, street analysis, track days, altitude testing and more -each test resulting in tweaks and revisions to the calibrations.  The end result is an obsessively tuned and optimized beast that will completely transform your vehicle to deliver that addictive power you crave.

IE's own in-house developed POWERlink cable and software gives you the freedom to quickly flash your car’s engine control unit (ECU) or transmission control unit (TCU) with your new IE performance tune.  The cable simply plugs into your vehicle’s OBD-2 port, from there simply follow the on-screen directions to quickly upload the tune. Adding horsepower is as easy as clicking FLASH NOW!  The flash tool also grants instant access to upgrade tune stages, switch fuel octanes, flash back to stock, perform engine diagnostics, read/clear codes and gather high-quality operating data via logging.
