APR 1.4 TSI/TFSI (EA211) ECU Upgrade
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.4T (EA211)!
APR’s ECU Upgrades are the value modification one can make to the 1.4T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install.
APR ECU Options
APR’s ECU Upgrades support various octanes without the need for any hardware modifications. Each upgrade is fully compatible with an upgraded intake, catback exhaust, or other minor bolt on modifications.
APR Stage I ECU Upgrade
The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 175 HP with 249 FT-LBS of torque. Gains as high as 38 HP and 62 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios. For those looking for a more modest bump torque with the same peak horsepower figures, a lower output file is available. To get more power, the vehicle can be outfitted with an upgraded intake, catback exhaust, or other minor bolt on modifications without requiring any new modification to the ECU.

Stage | ROW Fuel | Max HP | Max TQ | Max HP Gain Over Stock | Max TQ Gain Over Stock | |
---|---|---|---|---|---|---|
- APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode. | ||||||
- Max increases are based on APR's actual measured stock values and not those reported by VAG. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades. | ||||||
- Reported wheel figures measured on APR UK's dynojet using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. | ||||||

Stock As Measured by APR | 95 RON | 141 HP | 195 FT-LBS | |||
APR Stage I (Low Torque) | 95 RON | 175 HP | 225 FT-LBS | +35 HP | +39 FT-LBS | |

APR World Class Calibration Expertise
Tuning 101:
The 1.4T engine uses a Bosch MED17 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, adjusting the air/fuel ratio, advancing ignition timing, and more.
A Better Engine Management System:
The 1.4T’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. 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.
