Audi B8 S5/S4 3.0 TFSI ECU Performance Software and Power Pulley

VF-Engineering and HEX TUNING have developed an ECU Tune that has achieved outstanding results with the supercharged 3-liter V6 TFSI engine found within the current generation of S5 and S4 vehicles with Simos 8 EMS. This current generation of adaptive and intelligent ECU manages the engine health and output, constantly adapting the engine parameters during changing environmental and load conditions. This capability allowed VF Engr / HEX TUNING a sizable and yet safe latitude to implement and alter several parameters within the engine’s performance envelope including:
• Enhanced partial throttle/full throttle response


• Optimized air/fuel ratios
• Enhanced torque management
• Enhanced transmission/shift response


• Recalibrated variable valve timing


• Optimized boost management and wastegate control


• Limiters and governors raised/and or removed


• Designed and Made in California, USA.

The revised software is loaded via HEX TUNING’s proprietary module, which connects through the Audi’s OBDII port. The module then plugs into a standard laptop computer and the HEX interface does the rest.


HEX software is augmented with VF-Engineering’s supercharger Power Pulley, a beautiful piece that’s been carved from aircraft-spec aluminum and balanced for optimal, high-speed rotation.

The VFE Power Pulley provides significantly increased supercharger air flow and helps create substantial gains to both HP and torque. VFE’s Mustang MD500-AWD chassis dyno recorded an additional 83 ft-lb torque and 108 HP using less-than-ideal 91 octane fuel (but standard for CA).
In less than two hours the S5 is transformed from a GT car to a genuine, fire-breathing GTS.
