APR ECU UPGRADE STAGES
APR's new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. This upgrade makes the engine more powerful and more exciting. APR has extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by the APR engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with their new high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning, APR has created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.
The result of this work is nothing short of astounding. Not only have APR increased power, they’ve added many safety routines to ensure the engine and components are protected under demanding scenarios. Additionally APR has added features to enhance the driving experience.
APR has recalibrated the exhaust flaps to reduce backpressure and create consistent turbo spool characteristics. Sound characteristics are improved too, especially during free-rev, which sees its limiter raise in park and neutral. We’ve added a feature to enable exhaust crackle, which mimics much of the behavior of the RS models without being over-the-top and obnoxious. This enables during free-rev, downshifts, and lifting off the throttle. It’s optimized and includes safety routines to ensure component protection. Through proper torque management and ECU code changes, we’ve removed the requirement of a transmission tune to achieve full torque. APR has also optimized launch control for a better take-off and enabled boost building on the line. Additionally APR has defaulted the start-stop feature to the off position, removed the speed limiter, added left-foot braking or brake-boosting, and configured the ECU to send the correct calibration to the dash for the performance gauges.
To protect the engine and components, APR has spent a considerable amount of time tuning safety routines, some of which were not active from the factory. The ECU will protect the engine should the exhaust flaps fail as back pressure becomes too high. The optional exhaust crackle feature will turn off should components get too hot. The engine has advanced LSPI protection to prevent the engine from damage when being lugged in the tallest gears. Excessive intake air temperature, which is common on a dynamometer, will cause power to reduce to protect the engine. Furthermore, APR has added and calibrated protection routines for turbocharger pressure ratios, shaft speed, exhaust pressure, intake air temperature, coolant temperature, oil temperature, lambda, fueling system limitations, and more. All of this and more gives us confidence to offer an optional limited powertrain warranty through APR Plus!
APR Stage 1
The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 384-435 HP with 499-557 FT-LBS of torque depending on fuel grade. Gains as high as +86-144 AWHP and +137-214 AWFT-LBS of torque are available throughout the power band, depending on fuel grade and factory output, making the vehicle exceptionally quicker in all scenarios. For even more power, this stage is compatible with normal bolt-on hardware modifications.
APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, and 104 AKI in North America and 95 RON, 98 RON, 104 RON, and 108 RON in the rest of the world.
APR Plus
The APR Plus ECU Upgrade is the first step towards making more power, and it includes our limited powertrain warranty. This simple upgrade requires no engine hardware modifications, and produces 384 HP with 499 FT-LBS of torque. Gains as high as +86 AWHP and +137 AWFT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.
The APR Plus ECU Upgrade matches the performance of our Stage 1 ECU Upgrade (91 octane). To get even more power, you can add any of our other Stage 1 compatible products and still be covered under the APR Plus warranty! If you're not interested in the APR Plus limited powertrain warranty, and want even more power, check out our other Stages.
