INCLUDED OCTANES

Your IE tune purchase includes multiple fuel options that offer dramatic power increases. Using your IE POWERlink, switch between octanes as often as you like allowing you to run 91/93 pump gas or flash to our race gas 104 or ethanol files for a massive increase in HP & TQ in only minutes.

FULL E85

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.

E40 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 when running ethanol blends.

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.


ADVANCED MAPPING

The factory ECU calibration is full of regulations and compromises that limits horsepower/torque and dull the power delivery and throttle feedback. IE calibrators re-tuned the complicated mass flow modeled boost control mapping with advanced strategies to achieve precision boost request targeting that results in unmatched power delivery. The throttle mapping also receives a significant rewrite to deliver a linear and predictable throttle feedback. These refinements result from months and months of fine details that dramatically improves your conneciton to the car with a much sportier and precise feel.

BRAKE BOOST

Commonly used in roll racing, Brake Boosting allows you to build extra turbo boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" and leg up on the competition.

EGT OPTIMIZATION

Exhaust Gas Temperature (EGT) is the measurement of fuel mixtures exiting the exhaust and is used to determine the health of the fuel/air mixture entering the engine. IE engineers have spent countless hours adjusting boost air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for ultimate engine safety without sacrificing power on all octanes.

MAXIMIZED OUTPUT

This is not a simple dyno tune. IE's in-house calibration systems were used to reverse-engineer the factory ECU mapping on a professional OEM motorsport level. This grants our calibrators access to every ECU mapping parameter and the ability to add custom programming as necessary. Additional sensors and data collection systems are added as required to completely realign all safety protocols and sensors for the new max-performance ECU tune. Every tune parameter undergoes months of testing on our in-house dyno systems that utilize the world's only Sea Level Generator developed specifically to verify tune operations in any condition. Confidently drive from LA to Pikes Peak with power that will keep you smiling every mile!

DIRECT PORT

The IE POWERlink is a powerful direct-port tool that plugs directly into your vehicle's OBD-2 terminal. This grants instant access to flash and upgrade tune stages, switch fuel octanes, turn on/off features, flash back to stock, perform engine diagnostics, and record logs with the built-in data logger from the comfort of your own driveway.

OCTANE SWITCHING

All IE 4.0TT tunes include multiple octane options. Using your IE Powerlink, you can easily switch between calibrations for different fuels and unlock different power levels. Depending on the Stage, choose from 91, 93, 104, E40 and E85.

UPGRADE STAGES

Your POWERlink cable allows you to upgrade stages for matching hardware, switch between them, and flash back to stock as you need. Once you purchase a stage you also own all of its features, octanes, and any stage under it.

TOGGLE FEATURES

Simply plug-your IE POWERlink to quickly toggle between optional features such as launch control settings. The process is the same as adding a tune and can be turned off just as easily.

CODE READER

Pesky check engine light turn on? Save a trip to the shop and use your IE POWERlink to diagnose the problem. The easy to use code reader will pull up any trouble codes and once the issue is fixed, clear the code and get back to the fun.

DATA LOGGER

Verify the healthy operation of your engine using the built-in data logging function. Nothing is better than a piece of mind that your investment is operating optimally. First time data logging? This article will help show you the ropes: How To Data Log

IMPORTANT INFORMATION

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 IE POWERlinks do not include the required internal hardware need to flash the B9 2.0T calibrations. If you are purchasing credits with an existing IE POWERLINK, please be sure your serial number on the back begins with V4.
