Integrated Engineering ECU Performance Tune – Audi B9 S4/S5/SQ5 Integrated Engineering

Your 2017-2023 Audi S4 or S5 is the home to a turbocharged 3.0L V6 powerhouse begging to be let loose. IE’s performance calibrations unleash your car’s full potential right out of the gate. Maximized for incredible power at home on the drag strip and road course while maintaining full comfort and reliability on your everyday commute. Experience IE’s Performance ECU Software yourself with a simple install that takes only minutes from the comfort of your own driveway.

IE Stage 1 & Stage 2 software brings track-ready ECU programming to your turbocharged 3.0L V6 engine while retaining factory comfort and reliability. IE’s own tuning technology suite is used to completely reverse-engineer the factory ECU mapping, allowing our software engineers access to realign all safety protocols and sensors for the new performance calibration. 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!

IE Stage 1 ECU calibration dramatically increases performance with up to 505HP & 585TQ, transforming your turbocharged 3.0L into a truly performance-classed vehicle. IE’s advanced tuning strategies leave no hidden power on the table and safely max out the factory turbocharger’s capability. Engineered to operate on entirely stock hardware and compatible with basic bolt-ons (intake, turbo inlet, intercooler) without the need to retune.

IE Stage 2 performance software is a complete engine calibration for full bolt-on stock turbo builds running an aftermarket racing downpipe and catalyst. The unique B9 EA839 engines are equipped with a smaller factory turbo and large stock downpipe with incredibly minimal exhaust restrictions. Using advanced calibration techniques, IE calibrators can extract full peak power on pump gas and ethanol fuels on Stage 1 and 2 downpipe setups. However, the required hardware upgrades for stage 2 will increase airflow, lower intake air temps, faster IAT recovery, and produce an overall more efficient and faster vehicle on the same power.

Stage 1 & 2 Plus ECU tunes are calibrated to support increased fuel delivery from upgraded HPFP (High-Pressure Fuel Pump) internals providing additional horsepower and torque through the mid-range of the power band. Acceleration dramatically improves with a 52HP gain in the mid-RPM (peak HP number remains the same) and up to 75ft-lbs of additional torque on E85! Our matching Stage 2+ TCU transmission tune (sold separately) also includes optimized shift points that double down on the intense pull through the middle of the powerband, further increasing acceleration and faster 1/4 mile times.

ETHANOL FUELS
E85 & E40 blend ethanol fuels are included with all stages and unlock the most performance potential from our ECU tunes. Ethanol contains tons of oxygen, burns cooler, and has a high resistance to knock. This provides more horsepower and torque than running conventional gasoline and is much less expensive than race gas.

IE calibrators spent many months developing and testing ethanol blends on the B9 3.0T engines in many climates and elevations. Results were consistent that full E85 runs very close to or beyond the limit of the factory direct injection (DI) fuel system in the mid-range but allows for more power up top. IE’s E85 calibration keeps mid-range power in check to avoid lean conditions, misfires, and power loss then ramps it up top for amazingly fast and consistent track times in a drag racing scenario. E85 is also great for easy fill-ups at the pump for daily driving without mixing blends.

E40 is an ethanol mix of E85 with regular pump 91/93 fuel creating a lower ethanol content fuel. E40 offers the optimal ethanol content for the factory DI fuel system in the mid-range of the power band. The lower content ethanol allows this file to create the maximum power output from 3000RPM-4000RPM, perfect for road course and track racing. E40 will also result in a faster feeling car in most street driving situations.
