AUDI PERFORMANCE PARTS: APR 2.5T EA855 EVO Stage 1 ECU Upgrade for Audi TT RS (MKIII/8S) / RS3 (Facelifted) (MKIII / Typ 8V)

Product Features:

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 451-506 FT-LBS of torque, depending on octane. Gains as high as 66-132 HP and 88-146 FT-LBS of torque are available throughout the power band. To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU. Upgrading the small factory intercooler is highly recommended on this platform.

APR "Lo Grip" Stage 1 modes are equipped with a features that help to reduce wheel spin and aid in 60 FT and 0-60 times on street tires and unprepped surfaces. However, for vehicles equipped with much better tires and surface prep, an optional “High-Grip” mode is available to maximize launching performance!

APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI and E85 fuel grades in North America, and 95 RON, 98 RON, 102 RON, 104 RON, 108 RON and E85 fuel grades in the Rest of the World.

Please note, our 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.

  • Program switching allows the user to cycle through up to four different engine calibrations and operating modes all without the need for external hardware.
  • By selecting stock mode, the ECU calibration is reset to the factory calibration.
  • Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a specialty tool.
  • Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features will appear completely invisible until a user specified 2 to 4-digit security code is entered.
  • APR's octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.
  • When activated, Anti-Theft prevents normal operation of the engine even if the factory key is used. The vehicle will be completely immobilized until a user specified 2 to 4-digit security code is entered.

APR EMCS Programs and Features

APR’s Enhanced Modular Chipping System, (EMCS), brings selectable programs and features to the factory ECU, without the need to purchase external hardware switching devices. EMCS has the ability to completely rewrite the entire operating map data within the ECU, giving each program mode a completely different set of calibration changes. On this platform, this is contrary to the industry norm of capping limits, using multipliers, only swapping portions of a base calibration, or relying on knock activity to lower output. APR’s EMCS features and programs modes are activated via the factory OEM cruise control buttons, and optionally through APR Mobile. The vehicle’s cruise control will function normally while driving.
