Stage 1 delivers a significant increase in power and torque while retaining the factory hardware, making it an excellent option for completely stock D5 A8 and A8L vehicles.
ECU Tune Features
- Significant horsepower and torque gains throughout the powerband
- Improved throttle response and acceleration
- Optimized boost control and ignition timing
- Refined torque management strategies
- Smooth, factory-like drivability
- OEM safety strategies retained
- Stage 1 compatible with completely stock vehicles
Jackal Motorsports calibrations are developed using extensive data logging, dyno validation, and real-world road testing to provide consistent and reliable performance improvements.
AL552 TCU Tune Included With All Stages
Every Jackal Motorsports ECU tune for the D5 Audi A8/A8L includes a complete AL552 TCU calibration at no additional cost.
This is not simply a torque-limit increase. The Jackal Motorsports AL552 transmission calibration is engineered to work together with the ECU tune, allowing the engine and transmission to operate as a properly integrated powertrain.
The result is faster transmission response, improved shift behavior, and enhanced drivability while maintaining the comfort expected from the Audi A8 and A8L.
TCU Tune Improvements
- Increased clutch pressure for stronger, more consistent shifts
- Faster shift speeds under acceleration
- Optimized AMAX launch and AMAX shift behavior
- Improved shift points for better drivability
- Enhanced torque capacity for higher power levels
- Smoother gear changes during normal driving
By calibrating both the ECU and TCU together, Jackal Motorsports ensures the entire powertrain works seamlessly to deliver improved performance without sacrificing comfort or reliability.
Stage 1 Tuning
Jackal Motorsports Stage 1 is designed for completely stock Audi D5 A8 and A8L 3.0T vehicles.
The Stage 1 calibration delivers substantial horsepower and torque gains while retaining OEM hardware and maintaining smooth, factory-like drivability.
Stage 1 Crank Output: 407 HP / 472 TQ
Stage 1 Wheel Output: 335 WHP / 387 WTQ
Stage 2 Tuning
Jackal Motorsports Stage 2 is designed for vehicles equipped with common performance upgrades such as:
- Upgraded intake
- Upgraded intercooler
- Downpipe
Stage 2 is designed to further increase performance by optimizing the ECU calibration around the additional airflow and cooling capabilities of the supporting hardware.
Stage 2 Performance: TBD
Stage 3 Custom Tuning
Stage 3 is a fully custom calibration built around your specific hardware configuration and performance goals.
Rather than using a generic staged file, Jackal Motorsports can tailor the calibration to the modifications installed on your D5 A8 or A8L, making Stage 3 suitable for more extensively modified vehicles.
Flashing Options
Jackal Motorsports provides convenient options for tuning your Audi D5 A8 or A8L.
Jackal Flash-at-Home
Use the Jackal Motorsports Flash-at-Home platform to install your calibration remotely without requiring an in-person appointment.
In-House Dyno Tuning
In-house flashing and dyno tuning are also available at the Jackal Motorsports facility. An appointment is required.
Both flashing options allow for safe calibration installation, updates, and tuning adjustments while maintaining OEM ECU integration.
Luxury Refinement Meets Performance
The Audi A8 and A8L are designed to deliver a premium driving experience, and Jackal Motorsports tuning is developed with that character in mind.
The goal is not simply to make the D5 A8 faster. Jackal Motorsports focuses on delivering stronger acceleration, sharper throttle response, increased torque, improved transmission behavior, and smooth power delivery while retaining the refined driving characteristics that make the A8 a flagship luxury sedan.
