Porsche Cayenne (9Y0) 3.0T EA839 V6 APR ECU Upgrade (ECU-30T-EA839-9Y)

We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Porsche Cayenne (9Y) 3.0T engine with the Bosch MG1 ECU! Expect massive gains with up to 393-432 HP and 500-564 FT-LBS of torque on tap, depending on octane, from this simple software upgrade. Features: Delivers up to 393-432 HP with 500-564 FT-LBS depending on octane Max gains of +95-149 AWHP and +141-212 AWFT-LBS depending on octane Supports 91 AKI, 93 AKI, 100 AKI, and 104 AKI fuel grades Optional factory term limit matching limited powertrain warranty with APR Plus Standing RPM soft limiter increased Left-foot braking / brake boosting added Properly rescaled performance gauges Optimized launch control strategy for faster response and boost building Optimized driveline protection during launch Optimized thermal management and additional protection Optimized high-gear LSPI protection and turbocharger protection added Speed limiter removed Exhaust flaps recalibrated to provide better performance and increase sound during free-rev Exhaust crackle added while retaining temperature safeties (optional feature) Auto start-stop defaults to the off position No hardware required (Software only) Supports standard bolt on modifications Eliminated the need for a TCU upgrade to achieve full torque Free lifetime updates Direct OBDII port flash (No ECU removal) 30 day money back guarantee APR ECU UPGRADE STAGES Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve 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 our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we 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 we increase power, we’ve added many safety routines to ensure the engine and components are protected under demanding scenarios. Additionally we’ve added features to enhance the driving experience.   We’ve 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 an optional 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 with exhaust flap actuation, 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. We’ve optimized launch control for a better take-off and enabled boost building on the line. Additionally we’ve 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 we’ve 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 more we’ve 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 393-432 HP with 500-564 FT-LBS of torque depending on fuel grade. Gains as high as +95-149 AWHP and +141-212 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.
