Description

Jackal Motorsports Audi B8 S5 4.2 V8 ECU / TCU Tune

Available through United Performance

Jackal Motorsports writes its calibrations from the ground up rather than reselling an off-the-shelf map — every file is validated with data logging, dyno work and real street testing before it reaches a customer’s car.

Performance:

• Up to +30 WHP / +50 lb-ft over stock

Transmission Tune Included:

• A complete ZF6HP transmission calibration ships with the ECU tune at no extra cost — not a torque-limit patch.
• Progressive launch control, enhanced AMAX shift behaviour, rolling AMAX in Sport and Manual, smoothed shift logic for daily driving.
• If your TCU is locked, Jackal supplies the file free once an unlock is available.

Notes:

• Launch control, plus optional burble and 2-step switched from the cruise control stalk.
• ZF6HP TCU tuning for faster shifts and better drivability.
• Jackal holds the record for the fastest JHM-supercharged B8 S5 V8 quarter mile at 11.26 @ 126 mph — full weight, stock motor, manual car.

Fitment:

• Audi S5 B8 4.2 V8

Flashing:

• Flash at home with the Jackal tuning cable, or book an in-house flash by appointment.
• Buy the cable once and switch between stock and any purchased stage free, for life.
