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.

E40 ETHANOL BLEND

Ready to experience an absolute torque monster!? Mixing regular 91/93 pump gas and E85 at a 40% ethanol content (E40) creates a blend that stays within the safe limit of fuel delivery for the factory injectors. This allows the E40 calibration to produce the full torque output available from the twin-turbo V8, resulting in an insane 862ft-lbs of torque that translates to a pull with seat slamming g-forces.
An ethanol content sensor kit is highly recommended for blending E40.

104 RACE GAS

In areas that do not have readily available ethanol or track enthusiasts with accessable race fuel pumps, the included 104-octane race gas file also succeeds in a considerable jump in power over regular pump gas. Sunoco GT260 Plus 104 octane is used to develop this tune and is highly recommended for the best results.
104 Octane option included with Stage 1 and Pure 900 Hybrid.

BRAKE BOOST

Commonly used in roll racing, Brake Boosting allows you to build extra boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" or extra surge of power.

AUTOPROTECT

Even with the best tuning, unreliable fuel and mechanical failures still pose a risk to any engine. iE AutoProtect is your last line of defense against engine damage. If trouble pops up, AutoProtect lowers boost and power to keep your engine safe against damage. When conditions return to normal, power automatically restores. Our unique error code is triggered so we can help pinpoint the problem.

HARDWARE GUIDE

iE 4.0TT tuning suites are designed to work seamlessly with optional or required hardware options. While Stage 1 doesn't require any hardware upgrades, adding our intake, turbo inlet, and intercooler upgrades will result in increased airflow, lower intake air temperatures, and quicker heatsoak recovery for additional power increases.

TUNE UPDATES
Your tune purchase entitles you to free updates to any tune revisions, new octanes, standard features, or software updates. In the event the original vehicle manufacturer issues an ECU update, this will also be included to you through iE at no additional charge.

POWERLINK VINS
Have multiple cars in the family or friends that are also ready for an iE Tune? Your POWERlink Flash Tool can be used on up to 5 different vehicle VINs. Tunes sold separately.

TUNE REGISTRATION
Once a tune purchase is applied to your vehicle's ECU, the tune is permanently registered to the vehicle and non-transferable to other vehicles. Tunes can be transferred to a second party in the event of vehicle transfer of ownership only.

REQUIRES V4 IE POWERLINK
The Audi MG1 uses new and updated flashing protocols to read and write the ECU and TCU information. Older V3 POWERlinks do not include the required internal hardware need to flash the B9 3.0T calibrations. If you are purchasing this tune with an existing POWERLINK, please be sure your serial number on the back begins with V4.

Important Notes:
-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.
