Overview
APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. 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 ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. The software is installed to the vehicle's factory ECU through the OBD-II port, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

APR ECU Upgrade Stages
APR’s ECU Upgrades are available in multiple octanes levels. Each stage is fully compatible with an upgraded intake, catback exhaust, or other minor bolt on modifications. Each stage includes optimizations to the factory boost gauge making it react more quickly and corrections to the power and torque gauges to match the increased output. Furthermore, we’ve added left foot braking, removed the speed limiter, raised the rev-limiter and added a motorsport limiter, reenabled the exhaust crackle on modelse where it was removed (2019+), adjusted the factory exhaust crackle to protect the catalyst on Stage 1 and 1+ and enabled in more scenarios on Stage 2, optimized cold start, retuned the exhaust flap actuation for the best performance and sound in multiple modes, optimized high altitude mappings, retuned the throttle for better response, and completely optimized the driving experience for street and track use making for a much more enjoyable driving experience!
APR STAGE 1
The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications and produces 459-542 HP with 451-500 FT-LBS of torque. To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust, and various other bolt-on modifications all without requiring any new modifications to the ECU. This stage has optional high and low grip modes designed to reduce wheel spin and aid in 60 FT and 0-60 times depending on surface prep. APR recommends NGK heat range 9 (NGK-R7437-9) spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km.
APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI and E60-E85 Ethanol in North America, and 95 RON, 98 RON, 102 AKI, 104 AKI, 108 AKI and E60-E85 Ethanol in the Rest of the World.

Extreme Testing
APR’s ECU Upgrade has been full tested for the better part of a year prior to a public release. This includes summer and winter weather testing on multiple continents, high and low altitude testing, extensive track testing at multiple road courses, extensive drag strip testing and extensive road and daily driving testing. APR’s test vehicles are full instrumented with multiple sensors, including pre and post intercooler temperature and pressure sensors, pre and post turbine temperature and backpressure sensors, pre and post catalyst temperature and pressure sensors, and multiple pressure sensors throughout the intake system. APR test vehicles have seen over 700 HP in various configurations, on the stock engine internals, and have set multiple world records, including 10.5 second stage 1 quarter mile passes, and 9 second stage 3 passes.
