Description

Jackal Motorsports Audi B6/B7 S4 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:

• 25-70 HP depending on modifications and mechanical health
• Stage 1: 20-30 HP
• Stage 2: 35-50 HP
• Stage 3: 50-60 HP
• Stage 3+ on E85: 60-70+ HP

Hardware Required by Stage:

• Stage 1: stock cars, or catback exhaust and intake
• Stage 2: full exhaust, high-flow catted or catless downpipes and a ported intake manifold (headers help)
• Stage 3: all Stage 2 hardware plus Bosch EV14 550cc injectors
• Stage 3+ E85: full bolt-ons, upgraded pump and filter, Bosch EV14 550cc injectors

Transmission Tune Included:

• A complete full remote TCU flashing for both B6 and B7 (automatic cars) 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:

• Optional 2-step, burble and no-lift-shift, switchable from the cruise control stalk.
• 91/93 octane and E85 files available.

• Full custom tuning for supercharger and turbo kits.
