ADDITIONAL TUNE FEATURES

ETHANOL FUEL
Flashing the E85 fuel map allows easy fill-ups at the pump without mixing ethanol blends. This ethanol calibration delivers a massive increase in power over regular 91/93 pump gas while keeping mid-range power in check with the factory direct injection (DI) system and avoiding lean conditions, misfires, and power loss. E85 offers amazingly fast and consistent power delivery from the pump and is much less expensive than race gas.

Ethanol files are not available with Pure900 Turbo Tuning.

REQUIRES V4 IE POWERLINK
The Audi MG1 uses new and updated flashing protocols to read and write the ECU and TCU information.

If you are purchasing this tune with an existing POWERLINK, please be sure your serial number on the back begins with V4.

FITMENT GUIDE

• 2024 model years are equipped with a new ECU version and are not currently compatible. Our calibration team is working on expanding to the new ECU type. No ETA is presently available.
• Audi is currently implementing new security patches on the ZF8 transmissions that are being mated to the EA825 4.0T engine. These security patches are not specific to any particular model or year of vehicle. These security patches have not been fully cracked by the aftermarket and the cars require additional work for iE's calibrators to flash. If your car has this rare combination, you may experience a brief wait period to flash while our calibrators bypass the security patch.
• Not compatible with euro6 particulate emissions ROW (Rest Of World) GPF equipped vehicles.
