Description
Unlock the full potential of your Audi B7 RS4 4.2L FSI V8 with a Jackal Motorsports ECU Tune developed specifically for the B7 RS4 platform. Jackal Motorsports has tuned thousands of Audi B6/B7 S4s and RS4s worldwide, combining extensive research and development, real-world data, performance-shop collaboration, and customer feedback to continually improve its calibrations.
Jackal Motorsports focuses on more than peak dyno numbers. Each calibration is designed to improve power delivery, throttle response, drivability, cold-start behavior, and overall vehicle performance across the entire RPM range.
The Jackal RS4 tune is especially well paired with the GAS Omega intake for customers looking to complement the ECU calibration with an upgraded intake system.
Performance Gains
The Jackal Motorsports B7 RS4 tune provides claimed peak gains of:
- Up to +21 WHP
- Up to +20 ft-lbs
The calibration is designed to deliver improved power and torque throughout the RPM range while maintaining smooth and predictable drivability.
8500 RPM Rev Limit
Jackal Motorsports increases the rev limit to 8500 RPM, allowing the naturally aspirated 4.2L V8 to take advantage of its high-RPM powerband.
Optimized Normal & S Driving Modes
Jackal Motorsports provides refined driving maps for both Normal and S modes, with optimized throttle-input characteristics designed to make the vehicle more responsive while maintaining smooth operation.
In S mode, the exhaust flaps can be programmed to remain fully open, allowing the naturally aspirated V8 exhaust note to be heard more prominently during spirited driving.
Improved Throttle Response & Drivability
Jackal Motorsports calibrates the RS4 for improved throttle response and smoother power delivery throughout the RPM range.
The tuning is designed to eliminate undesirable driving characteristics such as harsh cold starts and jerky low-speed operation, providing a smoother experience during everyday driving while retaining the performance characteristics expected from the RS4.
Launch Control & 2-Step
The Jackal Motorsports B7 RS4 tune includes custom 2-step and launch control functionality, allowing drivers to optimize launches and add additional control during performance driving.
Optional E30 Tune
For customers running an appropriate ethanol blend, Jackal Motorsports offers an E30 calibration.
The E30 tune can provide approximately 20 WHP more than the 93-octane calibration, depending on the vehicle, fuel quality, modifications, and operating conditions.
De-Flapped & Flapped RS4 Support
Jackal Motorsports offers dedicated calibrations for both vehicles retaining their factory exhaust flaps and vehicles that have been de-flapped.
These calibrations are developed specifically around each configuration to ensure proper operation and drivability. Jackal Motorsports has invested extensive development time into optimizing both setups rather than relying on a single generic calibration.
Jackal Tuning Cable
The Jackal Tuning Cable provides the flexibility to flash your RS4 from home and switch between supported calibrations without additional switching charges.
Customers can freely switch between available files, including:
- Stock calibration
- 93-octane tune
- E30 tune
- Flapped configuration
- De-flapped configuration
This makes it easy to adapt your calibration when changing fuel, exhaust configuration, or other vehicle modifications.
Continuous Development & Free Updates
Jackal Motorsports continually develops its Audi V8 tuning platform by working with performance shops, customers, and its engineering team.
Software updates and improvements are provided free to Jackal Motorsports customers, allowing existing customers to benefit from continued development of the platform.
Proven Real-World Development
Jackal Motorsports develops its calibrations using extensive real-world testing rather than relying exclusively on dyno testing. Development has included data from city driving, highway driving, spirited driving, track use, and drag racing.
The goal is to deliver a calibration that provides stronger performance while remaining smooth and predictable during everyday use.
Jackal Motorsports also offers a 30-day money-back guarantee on its tuning.
