APR 1.8 TSI Generation 3 ECU Upgrade for the MQB Platform

Posted on September 3, 2014 – 9:00 am

Achtuning is pleased to present APR’s release of the ultimate engine control unit (ECU) upgrade for the Generation 3, 1.8 TSI engine as found in the MQB platform vehicles.  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.






The Continental SIMOS 12 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 in-house 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 from idle to redline. APR’s ECU Upgrade increases turbocharger boost pressure and optimizes cam timing, ignition timing, lambda and more to produce higher output. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to ensure a powerful ECU upgrade without derogating the engine’s drivability or reliability.

APR’s ECU Upgrade will provide an excellent leap in power and torque while retaining OEM knock control sensitivity and other built in safety features. The result is safely achieved power, optimized for various fuel grades found around the world. We call it Performance Without Compromise!

APR Stage I ECU Upgrade

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 334 ft-lbs of torque and 247 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 129 ft-lbs of torque and 90 horsepower. The increase in power directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices, APR’s engineers conducted several acceleration tests. During the 60-120 mph sprint, the APR Stage I equipped vehicle finished 11.6 seconds faster!

APR’s ECU upgrade is the best power per dollar modification for the new 1.8 TSI engine and takes the vehicle’s performance to similar levels typically reserved for higher output, sporty models, without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent vehicle.

Acceleration Enhancements:


Beyond power 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, drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating.

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 / Brake Boosting:


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. As is with all features APR adds to the ECU, this feature may be removed upon request.

Clutch Protection:


APR’s standard Stage I ECU Upgrade offers a large increase in low-end torque, which may overpower the factory clutch. While APR did not experience clutch slip at the advertised torque levels and even higher, others may due to clutch health and driving style. APR recommends upgrading slipping clutches, but has also created special software designed to deliver the same peak horsepower with a cap on low end torque to reduce or eliminate slipping. These specific files are available with various torque caps set lower than the standard Stage I ECU Upgrade. 

Torque Management:


Torque management plays a big role in how the vehicle feels and preforms, especially during moments of low gear, rapid acceleration. Typically front wheel drive vehicles 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 minimize wheel spin and maximize forward acceleration so the driver can focus on enjoying the additional torque and power on tap. We call it Performance Without Compromise!

APR Stage I ECU Upgrade Calibration Report

170 & 180 HP | 184, 200 & 207 TQ – Stock as reported by VAG
179 HP & 207 FT-LBS of torque – Stock as mesured and estimated at the crank by APR
239 HP & 321 FT-LBS of torque +82 HP @ 4,050 RPM / +117 FT-LBS of Torque @ 3,150 RPM – 91 AKI / 95 RON
247 HP & 334 FT-LBS of torque +90 HP @ 3,050 RPM / +129 FT-LBS of Torque @ 3,950 RPM – 93 AKI / 98 RON

- 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 VW. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades.
– Reported wheel figures measured on APR’s in house Dynapack Dynamometer with a US Spec 2014 Audi A3 Sedan DSG, using SAEJ1349 correction and an average of multiple runs. Crank figures estimated based on the measured wheel figures. Results will vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, and other modifications.

The APR Development Difference


APR DirectPort Programming:
APR’s patented DirectPort Programming is now available for the Simos 12.x ECU! Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicle’s OBD-II port. This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!


APR ECU Explorer:
APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates. These tools are also limited to a small, specific list of variables. APR’s ECU Explorer is capable of logging every variable found within the ECU. It’s capable of logging well over 100 variables at once with data rates as high as 100 samples per second. Synchronous data logging is available for fine-tuning.


APR ECU Composer:
APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies. ECU Composer takes calibration to a new level with APR’s Quick Flashing. APR’s Calibration Engineers can reflash the ECU in seconds rather than waiting lengthy periods of time between each flash.


APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR’s Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR’s engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this allows APR to make turbo upgrades operate as if intended by the OEM.
