APR Stage 1 ECU Tune
The APR Stage I ECU Upgrade is the first step towards making more power!
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.This simple upgrade requires no engine hardware modifications, and produces 305-328 HP with 371-382 FT-LBS of torque. Gains as high as 78-97 HP and 95-110 FT-LBS of torque are available throughout the power band. Optionally a low torque version of Stage I is available that puts less stress on the factory clutch.
APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for the new 2.0T engine. The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 381 ft-lbs of torque and 316 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 114 ft-lbs of torque and 87 horsepower. Even higher figures were achieved using race fuel. For those looking for a more modest bump in horsepower and torque, lower output software is available. In both cases the increase in horsepower and torque directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices and the local IHRA certified drag strip, APR’s engineers conducted several acceleration tests. During the quarter mile sprint, the APR Stage I equipped vehicle crossed the finish line 1.094 seconds quicker, with an exit speed 13.3 MPH faster!
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, valve lift, 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 – 305HP/ 371 Ft-lbs of Torque = 78 HP Gain over stock / 105 Tq over stock
Stage 1 – 93 Octane gas – 316HP/ 381 Ft-lbs of Torque = 87 HP Gain over stock / 114 Tq over stock
Stage 1 – 100 Octane gas – 328/ 382 Ft-lbs of Torque = 97 HP Gain over stock / 125 Tq over stock
To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU. APR recommends properly gapping the factory spark plugs to a tighter gap (Ex: 0.024" ±0.002" or 0.6mm ±0.05mm), properly installed and torqued (Ex: Per the manufacturer's specifications), and maintained with a shorter changer interval (Ex: 10,000-15,000 mi or 16,000-24,000 km).
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.
APR Exhaust Crackle
Enhance your exhaust note just like Audi’s latest RS models! The APR Exhaust Crackle, lovingly called “pops and bangs” by many, adds a distinct crackle to the exhaust note upon lifting off the throttle, gear changes on a manual, decelerating, or while free revving at a stand standstill. This optional feature is available at no cost, at the time of flashing, for most compatible ECUs at stage 2 and higher stages. For convenience, the feature is only enabled when the vehicle is placed into sport mode or while free revving the engine. Lastly, for safety, this feature has built in hardware protection limits, and will only function when it’s considered safe to do so. (Please note: MK7 GTI video shown)
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.
