APR Stage 3 ECU Upgrades are now available for the 2017-2018 2.5 TFSI EVO as found in the RS3 and TTRS. MY2019 ECUs to follow.
This stage is available for multiple setups, and are all designed around using a drop-in turbocharger upgrade. Stage 3 has specific software for the TTE700 and GTX3582 drop-in turbo upgrades. Both require a APR TCU Upgrade, race DP exhaust system, midpipes, 980cc port injectors, turbocharger inlet system, intercooler, and 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. The TTE700 requires the included wastegate actuator. The GTX3582 requires the included turbosmart wastegate actuator and MAC 3-port solenoid. A proper 500 LPH+ @ 6 bar LPPF is required to run E85, but the stock LPFP is ok for all other fuels.
The TTE700 produces 576-713 HP with 523-536 FT-LBS of torque. the GTX3582 produces 581-740 HP with 511-555 FT-LBS of torque. RHD vehicles without the turbo inlet will experience reduced output. In all cases, torque is kept flat to aid in component longevity.
This stage has a optional high and low grip modes designed to reduce wheel spin and aid in 60 FT and 0-60 times depending on surface prep. Additionally this stage is available with optional exhaust crackle modes. The more aggressive modes increase the length, duration, intensity, and operating modes of the exhaust crackle. Aggressive modes are only recommended with testpipes.
APR Stage 3 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.
Please Specify which Turbo Upgrade you will be using when ordering.
Please note, the E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself and follow our switching guide. For maximum safety, especially on vehicles that see road course use, or long autobahn top speed runs, 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. DO NOT remove or unplug the exhaust valve actuator motors. Doing so will cause the ECU to greatly reduce output.
