Note: 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.

C8 4.0T STAGE 1 ECU TUNE

IE Stage 1 C8 EA825 ECU calibration dramatically increases hidden performance with up to 828HP and 862ft-lbs! IE's advanced tuning platform releases hidden power, maximizes the drive feel, boost delivery, throttle response, and powerband to completely transform your 4.0TT engine into a supercar powerhouse. Engineered to operate on entirely stock hardware or with an upgraded intake and intercoolers for the most performance.

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!
