APR IS20 Turbo Upgrade
This ECU Upgrade requires the factory IS20 turbocharger, found on the MK7 GTI, and seperate ECU Upgrades are available for use with the factory downpipe exhaust system or a FWD Downpipe or AWD Downpipe.
With the factory exhaust downpipe it produces 274-306 HP with 308-326 FT-LBS of torque. Gains as high as 104-136 HP and 113-138 FT-LBS of torque are available throughout the power band.
With a FWD Downpipe or AWD Downpipe it produces 284-319 HP with 311-330 FT-LBS of torque. Gains as high as 114-149 HP and 117-145 FT-LBS of torque are available throughout the power band.
APR highly recommends the vehicle be outfitted with an upgraded intake and intercooler. To get more power the vehicle can be outfitted with a catback exhaust and other small modifications without requiring any new modification to the ECU. APR's TCU Upgrade may be required to prevent transmission slip, and is required to acheive a higher redline. 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 manufacturers specifications), and maintained with a shorter changer interval (Ex: 10,000-15,000 mi or 16,000-24,000 km).
APR ECU Upgrade Included Features
APR World Class Calibration Technique
Engine Tuning 101:
The 1.8T engine uses a Continental Simos 12 and 18 ECU for engine management. Basically, it’s a computer that tells the engine how to operate. Tuning software, like the APR ECU Upgrade, tells the engine how to make more power. It does this by running more boost pressure, optimizing the cam shaft positions, valve lift actuation, adjusting the air/fuel ratio, advancing ignition timing, and more.
A Better Engine Management System:
The 1.8T’s ECU is incredible. Without the driver knowing otherwise, the ECU makes intelligent adjustments to the engine’s operations to keep it running smoothly. Unlike ECUs found in many other makes and models, when properly tuned, the ECU eliminates the need for custom tuning to maximize output, even when weather conditions change dramatically.
How APR Differs from the Competition:
The ECU is powerful, but extremely difficult to master. Without mastery, the ECU must be simplified, removing what makes it so desirable. The result is an incomplete product that often requires end user adjustment to maximize output in limited scenarios. On the contrary, APR’s Engineers spent years mastering the ECU to unlock its full potential. With complete access to the thousands of maps, tables and variables within, as well as a high-level understanding of how it works, APR’s Engineers were able to take advantage of everything the ECU has to offer. Power is maximized in nearly all scenarios, eliminating the need for end user adjustments. High performance operational modes are enabled and calibrated to deliver smooth daily driving, with a snappy and responsive throttle during moments of spirited driving. Mastery of the boost control system makes for an impressively predictable driving experience as the turbo spools quickly, delivering instant power, while torque-by-gear helps with traction control and protects the engine from being lugged out in tall gears. Lastly advanced high-output protection routines are enabled, allowing the ECU to make constant adjustments to airflow and fuel to cool and protect the engine, all without the driver knowing otherwise.
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.
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.
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.
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.
