Jackal Motorsports ECU & TCU Tuning for Audi B9 S4, S5, and SQ5 3.0T
Available through United Performance
Maximize the performance of your Audi B9 RS4 or RS5 2.9T with Jackal Motorsports ECU and TCU tuning, engineered for substantial horsepower and torque gains, sharper throttle response, and optimized transmission shifting. Offering Stage 1, Stage 2, and fully custom Stage 3 calibrations, each tune is developed through extensive real-world testing and tailored to your specific hardware and fuel setup. Designed for both street and track performance, Jackal tuning enhances turbo efficiency, power delivery, and drivability while maintaining long-term reliability for your twin-turbo 2.9T Audi.
At Jackal Motorsports, we donโt chase numbersโwe chase results. Our Stage 1, Stage 2, and fully custom Stage 3 tuning solutions for the Audi B9 RS5 are developed through extensive testing and real-world validation, with a focus on refinement, drivability, and long-term reliability.
Stage 1 โ 93 Octane
An upgraded intake is strongly recommended for Stage 1. Improved inlet flow reduces restriction ahead of the turbochargers and increases available airflow, while also enhancing induction sound and throttle response.
While not required, an upgraded intercooler has the largest impact on real-world performance. The factory RS5 uses a water-to-air charge cooling system, which can quickly heat soak under sustained load. Improving charge air coolingโwhether through an upgraded air-to-air solution or an enhanced water-cooled systemโsignificantly reduces intake air temperatures, allowing the engine to maintain boost, timing, and power consistently rather than tapering as heat builds.
For owners focused on repeatable performance rather than short bursts, the intercooler is the single most effective hardware upgrade.
Stage 2 โ 93 Octane
Stage 2 requires an upgraded intake, high-flow downpipes, and an intercooler. At this level, airflow and thermal control are no longer optional. Increased cooling capacity is critical to sustaining higher load and power without instability, excessive heat, or power falloff during longer pulls.
Stage 3 โ 100% Custom, Tailored to Your Exact Setup
Stage 3 RS5 tuning is not a one-size-fits-all file. It is a fully custom calibration built around your exact hardware, fueling, and goals.
Stage 3 is intended for vehicles running upgraded turbochargers, HPFP, injectors, and supporting fuel system modifications, and supports 93 octane through E40.
Custom Stage 3 tuning is available for:
- Upgraded turbochargers (hybrid and full-frame)
- Upgraded HPFP
- Upgraded injectors (including Spool Performance)
- Custom or one-off fueling configurations
Fueling limits are respected, injector operation is kept within safe ranges, and torque delivery is carefully shaped to ensure clean, reliable performance. All tuning is validated using real street dataโnot just dyno pulls.
Proven Stage 3 performance on E40:
โข 9.92-second quarter mile
โข 2.35-second 0โ60 mph
Full AL552 TCU Tune โ Included at Every Stage
Every Jackal RS5 tune includes a complete AL552 TCU calibration, not a partial or patched file.
- Progressive Launch Control
- Enhanced AMAX shift behavior
- Rolling AMAX in Sport and Manual modes
- Second Gear Launch option
- Smoothed shift logic for daily driving and performance use
TCU tuning is included at no additional cost. If your TCU is currently locked, a file will be provided free of charge once an unlock becomes available.
Proven Performance
Jackal Motorsports holds the current stock turbo quarter mile record for the B9 and B9.5 RS5, running 10.51 @ 130 MPH.
These results, combined with our single-digit Stage 3 E40 performance, demonstrate Jackalโs ability to extract real-world performance while maintaining stability, drivability, and reliability across both stock and upgraded turbo configurations.
More Than Just Power
At Jackal, every calibration is about balance. We maximize output without sacrificing safety, pursue performance without compromising reliability, and enhance drivability without adding unnecessary complexity.
