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!

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.

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.

Ie really came through

I am a long time car enthusiast and have tuned many audis over the years. I never ever review anything because I feel like I pay for a product I expect it to work and I absolutely don't owe any company anything to write a review and my time is valuable. However, this is the rare review I felt compelled to write.

I had take my 2022 audi sq8 to 3 different tune shops to chip and all of them failed to be able to access the ecu. They told me the ecu is locked and I wasn't able to tune.

I found integrated engineering online and I was very skeptical since there are so many tuners online most of which reselling tunes or subpar add on parts that sit between the ecu and the car. I emailed them to confirm if their tune would work for me. They said yes, I wasn't convinced, I sent them screen captures of my ecu sticker and ecu data from vagtool odb reader etc. They still said yes we can tune your car. I still wasn't convinced. I asked them if I got their tune and if it didn't work would they return it and not charge restocking fee they again said yes. I'm sure they thought I was nuts.

Well guess what it not only worked but it is one of the best tunes I've ever had!

Phenomenal tune and phenomenonal software. I used the app on Android platform and I was so scared I would brick my ecu and it took quite a bit through the various checks and uploads but in the end it worked. I cleared the remaining codes post tune and it was flawless first time out. The key to their tune I believe is the…

I have to say I was very nervous and skeptical of all of the performance tune upgrades, but ended up thrilled with IEs ecu upgrade for the 2022 Audi S8. Sound and acceleration are definitely noticeable in an awsome way! Definitely worth the $1500 and a "big bang for the buck" as well! Hoping IE will design some other upgrades for the 2022 S8 in the future.

Awesome!

The way the car should have been from the factory. I shouldn’t have waited 20,000 miles to do it!

IE Tune 2023 SQ7

Just do it already, pull the trigger, don’t hesitate. On 91 octane tune the car comes alive, no hesitation. On Dyanmic mode with your foot on the floor, it’s a beast that lets you know that there is now an alter ego of unlimited acceleration with pops and burble sounds when you let off. Daily driving in comfort mode is very smooth yet aggressive when pushed.

Stop thinking - buy it

This is my second tune I've purchased from IE. I applied the Stage 1 tune to my 2013 S4 a few years back, and loved it so I was excited to get the tune for my SQ7. The new bluetooth Powerlink made it super simple along with the app, and the whole process of applying the tune took about 30 minutes. And once I had the chance to check it out, I was blown away. The difference this tune made was astonishing - much more noticeable than the one for my S4. The shifting is crisper, the transmission is more aggressive, the exhaust is much more noticeable, and the power....it's always there. Buy this tune, you need it.
