APR is pleased to present the ultimate engine control unit (ECU) upgrade for the high output 2.0T EA113 Engines! 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 on select models.
The ECU’s MED 9 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.
Motorsport Rev Limiter:
APR’s Motorsport Rev Limiter allows the engine to reach max RPM without the ECU slowing down acceleration nearly 150 RPM earlier. The result is more power to redline and a definable redline feeling as seen on Audi Quattro GMBH vehicles such as the RS4, RS5 and R8.
Left Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle's throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track.
APR’s Stage I ECU Upgrade is designed for vehicles with little to no modification. Expect higher peak numbers of 310 horsepower and 311 ft-lbs of torque, but also gains of up to +57 horsepower and +58 ft-lbs through the power band.
When running the intake specific software with a full high flow intake, more gains can be had. Expect higher peak numbers of 337 horsepower and 309 ft-lbs of torque, but also gains of up to +72 horsepower and +61 ft-lbs through the power band.
APR’s Motorsport Launch Limiter is an optional feature that eliminates turbo lag and provides a user adjustable launching RPM to aid in vehicle acceleration from a complete stand still. Simply hold the clutch and accelerator while the vehicle is stationary and the engine’s RPM will hold at a predefined limit while boost pressure builds using a “clean,” catalytic converter safe, strategy. With the vehicle stationary, handbrake applied and clutch disengaged, the driver can set the launch RPM by raising the engine’s RPM and pressing the brake pedal to set and save the desired launching RPM. With practice, this method can result in violent acceleration off the line!This feature is for manual transmissions only.
APR’s Motorsport No-Lift Shift is an optional feature that allows the driver to maximize acceleration by reducing power, boost and time lost during a gear change. With the vehicle above 20 km/h and the accelerator pedal held above 98%, during a gear change, the strategy activates. The throttle remains open and boost pressure is not vented, resulting in more power immediately after a shift. This is achieved using a “clean,” catalytic converter safe, strategy, while the ECU automatically sets the appropriate time necessary for a torque intervention, allowing proper syncro alignment. No end user adjustment is necessary. The driver simply focuses on shifting as fast as possible! This feature is for manual transmissions only.
