Alabama-based tuner
APR has unveiled its new APR Plus and Stage 1 ECU upgrades for the VW Group’s
5.2-liter FSI V10, which means they’re compatible with models such as the Audi
R8 V10, V10 Plus and RWS, as well as the Lamborghini Huracan LP580-2 and
LP610-4.
APR’s Stage 1 ECU
upgrade was designed to offer more horsepower and torque without impacting
driveability, whereas APR Plus offers a limited powertrain warranty on all APR
Stage 1-upgraded vehicles running on 95 RON fuel. By installing the Stage 1 ECU
upgrades to the 5.2-liter V10 engine, you will see an overall performance
increase of 104 HP and 86 Nm of torque.
Other improvements
include support for left foot braking, speed limiter removal, a raised 9,000
rpm rev limiter, fully adjusted thermal management, optimized throttle, intake
and exhaust flaps, lambda control, port/DI splitting, cam phasing, more
aggressive ignition timing and an update to the factory power and torque
gauges.
The Stage 1 upgrade
also allows for on-demand ECU program switching (up to four modes), which
includes a reduced-speed valet mode and quiet cold starting. Moreover, it
allows the engine to run on 91 AKI (95 RON) and 93 AKI (98 RON) gasoline and
E60-E85 ethanol fuel.Unfortunately, no straight line performance figures were
released, although we can imagine that those 100 extra horses will make the
already very fast R8 and Huracan a little bit livelier.
