APR Stage 1 ECU Tune
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5 TFSI. 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 on early ROW models and through APR's CCD on newer models. 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
Gains over Stock
Stage 1 – 91 Octane gas – 459 HP / 451 Ft-lbs of Torque = 66 HP Gain over stock / 88Tq over stock
Stage 1 – 93 Octane gas – 476 HP/ 470 Ft-lbs of Torque = 86 HP Gain over stock / 108 Tq over stock
Stage 1 – 100 Octane gas – 516 HP / 498 Ft-lbs of Torque = 106 HP Gain over stock / 137 Tq over stock
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.
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.
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.
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.
Torque Management
Torque management can play a big role in how the vehicle feels and performs, especially during moments of low gear, rapid acceleration. Typically front wheel drive vehicles can suffer from excessive wheel spin during these moments due to the massive amount of torque on tap from the ECU upgrade. APR’s ECU Upgrade uses advanced torque management routines to help minimize wheel spin and maximize forward acceleration so the driver can focus on enjoying the additional torque and power on tap.
Race Fuel Information: Higher octane fuel typically allows APR’s engineers to create more power and torque by achieving greater ignition advance. However, on this application, APR’s engineers were able to achieve MBT, or minimum spark timing for best torque, on 93 AKI fuel with the IS38 turbocharger and APR downpipe. MBT is essentially the point where greater ignition advance no longer results in more power and torque. By using APR’s upcoming Ethanol Flex Fueling upgrades and Ethanol fuel, greater peak power was achieved due to the fuel’s highly oxygenated nature.
30 Day Money Back Guarantee
All APR ECU Upgrades include a 30-day money back guarantee with no questions asked. If for any reason the owners is dissatisfied with the APR ECU Upgrade, they may return to the place of purchase for a full refund, provided they are within the 30 day period from the time of the initial purchase. **Refund is on ECU Software only, there is a labour fee applied to flash the vehicle back to factory
IMPORTANT PRICING AND AVAILABILITY DETAILS: Availability and ECU Compatibility: Stages, programs, and features may not be available for all ECUs.- ECU Revision Notice: Multiple ECU revisions exist for each platform. APR software may be temporarily unavailable when factory updates are applied. An APR dealer can check availability in person, or over the phone if the ECU boxcode/revision is known
