APR Presents the MK7 GTI ECU Upgrade!
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the Generation 3, 2.0 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 & 18 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, valve lift, 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 1 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 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 100 AKI octane race fuel. The increase in power 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 ECU upgrade is the best power per dollar modification for the new 2.0 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.
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!
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.
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.
