APR Stage 1 ECU Performance Engine Tune For 9Y Cayenne Turbo GT 4.0T EA825

Unleash the True Potential of Your Porsche Cayenne Turbo GT

We're thrilled to introduce APR's Engine Control Unit (ECU) Upgrades for the powerful 4.0 TFSI EA825 engine found in the Porsche Cayenne Turbo GT! With up to 795 HP and 864 FT-LBS of torque, this upgrade transforms your car into a performance powerhouse, delivering exhilarating power and unmatched driving excitement.

Power. Precision. Protection.
Our new ECU software is the result of months of meticulous engineering and real-world testing, far surpassing the typical aftermarket solution. By equipping our development vehicles with high-speed data loggers, turbo shaft speed sensors, thermocouples, and other precision instruments, we fine-tuned hundreds of parameters and corrected countless protection models across multiple octanes to achieve flawless performance, enhanced safety, and unmatched reliability. We're so confident in its reliability that we even offer an optional factory term-limit matching limited powertrain warranty with APR Plus!

What does that mean for you?
It means blistering acceleration with gains of up to +171-181 AWHP and +209-212 AWFT-LBS over stock, depending on factory output, with just tuning alone, delivering a rush of power that transforms your driving experience. We recorded 2.x-second 0-60 mph sprints that will drop your stomach and pin your back to your seat like never before! You'll enjoy smooth, linear throttle response and a torque curve that feels endless, providing relentless pull across the rev range. Race-proven features like brake boosting and speed limiter removal unlock new levels of control-perfect for track days or spirited driving. All of this is backed by advanced safety routines that ensure your engine remains protected, even under the most demanding conditions.

Performance without compromise
Our ECU upgrade includes advanced safety features that go above and beyond by correcting modeled sensor data within the ECU and enabling and calibrating new protection routines. We've optimized turbocharger protection by monitoring shaft speed and respecting overspinning limits, excessive exhaust backpressure, and unstable pressure ratios. Low-speed pre-ignition (LSPI) protection prevents engine damage in high gears. Thermal management actively reduces power to prevent overheating of critical components, lowers cooling setpoints in sport mode, and reduces power until your oil reaches the proper temperature. Fuel system optimization ensures safe, reliable operation within critical fueling limits. Additionally, drivetrain shock protection optimizes torque delivery to reduce stress on critical components. The result? Massive power gains with the confidence that your engine and drivetrain are protected for the long haul.

Enhanced Driving Experience
We didn't stop at raw power-APR's ECU upgrade enhances every aspect of your driving experience. To truly experience the sound of this engine, we've increased the standing RPM limiter, allowing higher revving in neutral and park while enabling the exhaust crackle in this mode. Optionally, you can enable even louder exhaust sounds with more aggressive burbles, pops, and bangs in all scenarios-or keep it stock for a more refined experience.

Furthermore, we've added left-foot braking and brake boosting for greater control on and off the track, while the speed limiter removal unleashes your car's full top-speed potential. The Auto Start/Stop memory ensures your preferred setting is always ready, putting you in control every time you start the car, and it disables automatically in sport mode. Finally, we've removed the cap on the boost gauges so you can see the full range present at higher power levels!
