ECU Upgrades

APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU. APR’s EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU.

The engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR’s Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes ignition timing, cam timing, lambda and more to produce higher output!

APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world.

Acceleration Enhancements

Beyond horsepower and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.

Speed Limiter

APR’s ECU upgrade increases the vehicle’s top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun.

Increased Fuel Economy

APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved.

Making good better
The stock exhaust system has crimped tubing that obstructs exhaust flow, and robs horsepower. We fixed that. The AWE Tuning Touring Edition Exhaust and Downpipe was designed using CAD modeling software to produce smooth gradual bends, eliminating flow interference.

Sound Perfection: AWE Tuning 180 Technology™
As exhaust gases exit the engine and flow into an AWE Tuning 180 Technology™ equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

APR – EXHAUST

RSC™ or Reflective Sound Cancellation allows for maximum exhaust gas flow while completely eliminating unwanted in cabin sound resonance known as “drone”. Reflective Cancellation bounces the undesirable sound waves into each other to attenuate the wave and eliminate the low frequency tones that create drone. Each RSC™ muffler is tuned to eliminate specific, undesirable sound frequencies allowing only the engine’s true and desirable exhaust note to be heard and improving performance.

APR- TURBOCHARGER UPGRADE KIT

The APR Turbocharger Systems features many upgrades over the factory equipped turbochargers, making it an excellent upgrade. The CNC-machined, billet aluminum compressor wheel and higher flow exhaust turbine wheel expand the turbo’s efficiency range, allowing for higher output across a wider RPM range.

True to APR’s mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. Compressor surge is avoided to increase the reliability of the system without limiting the area under the curve typically experienced during a top speed acceleration run. APR’s endless pursuit of perfection has resulted in the most comprehensive turbocharger systems and tuning packages in the world.
