Stage 1 Tune
Jackal Motorsports Stage 1 is designed for stock vehicles and vehicles equipped with basic bolt-ons such as an intake or cat-back exhaust.
Recommended setup:
- Stock vehicle
- Aftermarket intake
- Cat-back exhaust
Expected gains: 20-30 HP
The Stage 1 calibration is designed to provide improved throttle response, stronger power delivery, and increased performance without sacrificing everyday drivability.
Stage 2 Tune
Stage 2 is designed for more extensively modified naturally aspirated 4.2L V8 vehicles.
Requirements:
- Full exhaust system
- High-flow catted or catless downpipes
- Ported intake manifold
- Headers recommended
Expected gains: 35-50 HP
The Stage 2 calibration is optimized around the increased airflow provided by the upgraded exhaust and intake system.
Stage 3 Tune
Stage 3 is intended for heavily modified naturally aspirated B6/B7 S4 builds.
Requirements:
- All Stage 2 modifications
- Bosch EV14 550cc fuel injectors
Expected gains: 50-60 HP
The calibration is designed around the additional airflow and fueling capacity of the Stage 3 hardware.
Stage 3+ E85 Tune
Stage 3+ E85 is designed for full bolt-on B6/B7 S4 builds running E85.
Requirements:
- Full bolt-on modifications
- Upgraded fuel pump
- Upgraded fuel filter
- Bosch EV14 550cc fuel injectors
- E85-compatible fuel system
Expected gains: 60-70+ HP
E85 tuning allows Jackal Motorsports to optimize the calibration around the increased octane and fueling characteristics of ethanol.
Full Custom Tuning
Jackal Motorsports provides fully custom tuning for B6/B7 S4 applications that go beyond traditional naturally aspirated Stage 1-3 configurations.
Custom tuning is available for:
- Supercharger conversions
- Turbocharged builds
- Custom engine combinations
- High-performance fuel systems
- Specialized track and street configurations
Jackal Motorsports has worked with major supercharger platforms and provides custom calibration designed around the specific hardware and characteristics of each vehicle.
Full TCU Tuning
Jackal Motorsports offers full remote TCU flashing for B6 and B7 Audi S4 models, providing transmission calibration alongside the ECU tune.
The TCU tuning is designed to improve transmission behavior and complement the increased power and torque provided by the ECU calibration.
Jackal Tuning Cable & Remote Flashing
ECU flashing is performed remotely using the Jackal Tuning Cable and Jackal tuning suite. The system provides a convenient way to flash your vehicle without requiring an in-person tuning appointment.
Jackal Motorsports also provides solutions for specialized applications, including immobilizer-related issues and manual transmission swaps.
Once you purchase a Jackal tune and cable, you can freely switch between the factory calibration and available staged calibrations without paying additional flashing fees.
Proven B6/B7 S4 Performance
Jackal Motorsports has developed and tested high-powered B6/B7 S4 4.2L V8 applications, with reported performance figures that demonstrate the potential of the platform.
Jackal reports its shop car producing more than 760 WHP and achieving a 5.09-second 60-130 MPH time on an E30 blend.
A customer B7 S4 is reported to produce more than 1,000 WHP while achieving a 60-130 MPH time in the mid-4-second range.
AMTuned's shop car reportedly holds a 10.71-second @ 134 MPH 1/4-mile record while running Jackal Motorsports tuning.
Jackal Motorsports also reports a recent naturally aspirated manual B6/B7 S4 1/4-mile record of 12.86 @ 106 MPH using its Stage 1 93-octane calibration.
These reported results demonstrate the development potential of the B6/B7 S4 4.2L platform when paired with the appropriate hardware and calibration.
Optimized for Your Vehicle
Jackal Motorsports tuning is not designed around a generic one-size-fits-all approach. ECU calibrations are optimized around the vehicle's modifications, fuel type, operating temperatures, and intended use.
The goal is to provide stronger performance without unnecessary timing pull or compromised drivability.
From daily commuting to spirited street driving and track use, Jackal Motorsports focuses on creating smooth, predictable power throughout the entire RPM range.
