Description
The Syvecs Plug-and-Play ECU Kit for the Audi RS3 8Y2 Facelift is a fully integrated engine management solution engineered specifically for vehicles equipped with the DNWC 2.5 TFSI engine.
Designed to interface directly with the RS3’s advanced electrical architecture, this kit connects to the factory wiring loom using a true plug-and-play solution, requiring no cutting, splicing, or permanent vehicle modification. Once installed, the Syvecs ECU integrates seamlessly with the vehicle, unlocking a vastly higher level of engine and drivetrain control while retaining all standard OEM functionality.
This solution is aimed at overcoming the increasing restrictions of modern factory ECUs, delivering motorsport-level control while preserving OEM drivability and system integration.

All while preserving OEM refinement, drivability, and vehicle system integration.
Based on the Syvecs S7 Plus ECU, the Plug in ECU integrates with all the OEM Audi Electronics but allows full control of the engine offering some of the following features:
- Live Tuning of every aspect of the engine’s calibration, including signals sent to the DSG.
- Full Direct Injection and Pump Control.
- 10 Injector Support with 5 x DI Injectors and 5 x Port Injectors.
- Option to Remove DI injectors (Very high HP applications)
- Ability to select desired engine map, boost level, traction and launch control levels through steering wheel buttons or External switches
- Fully adjustable Launch control with Anti-lag strategies and Ramp in Maps.
- Full Variable Valve Timing control.
- Flex Fuel control option.
- Cruise Control option. (Radar Control and ACC/Lim Function NOT Supported)
- Fully functional with every other control module on the car.
- Closed loop Lambda Control with OEM Wideband Sensor.
- Fully adjustable closed loop boost control with launch level adjustments and trims for turbo speed, air charge, engine coolant temp, exhaust gas temperatures etc.
- Monitor and trimming of exhaust gas temperatures with Syvecs KT8 and Ktype Thermocouplers.
- Built in data logging using a market leading analysis software of up to 8 hours, with data rates at up to 1000hz.
- Rolling Antilag / Pit lane limiter strategies, great for building boost on a roll.
- Configurable engine safety trips on important parameters like lambda, oil temperature, oil pressure, air temp, coolant temp and more.
- Anti-theft and valet modes.
- Super fast connection via RJ45 Ethernet port for live tuning anywhere in the world or even remotely if on track and connected to a wireless unit.
- Adjustable traction control strategies based on lateral g and individual wheel speed monitoring.
- 4 programmable target slip maps. An immediate torque reduction can be applied by the ECU via ignition retard or a fuel cut.
- Configurable Engine Safety Trips on all important parameters such as oil temperature and oil pressure.
- Fuel pump control of both main, and sub pumps, as well as relative fuel pressure monitoring and limiting in the event of fuel pressure dropping on boost.
- 4 different Pedal to Throttle Angle maps with multipliers for different parameters e.g. speed. Again adjustable via steering wheel buttons.
- Configurable individual cylinder closed loop knock control, to suit any cylinder modification with adjustments to frequency, windows for listening and gains for each cylinder. Ability to trigger full cylinder shutdown in severe knock conditions.
- Change torque reduction levels on shifts. Essential for very high power applications where the maximum reduction available via the stock ECU is not enough to prevent damage to components.
- Ability to change Torque ramp in after launch.
- Change throttle blip requests to match your torque band. Especially useful on oversized turbo installations.
- Run up to 7bar map sensors.
- Change injector dead times based on voltage levels for proper control.
- Change injector end angle to ensure injection point is properly calibrated.
- Ability to fit any type of external sensor to monitor and trigger safety trips from anything such as crank case pressure to damper position.
- Ability to use any size DBW throttle body e.g. Chevrolet LS7.
- Wet and Dry – wet and dry nitrous control with ability to drive solenoids directly and control n20 heaters via pressure monitoring.
- Ability to control any external vehicle features based on sensor inputs e.g. Adjustable rear wing linked to G force or exhaust control valves.
- Connect to external displays or loggers via a spare CAN connection - Check our TinyDash v2 - https://www.syvecs.com/product/syvecs-tinydash-v2-touchscreen/.
- View any input live with built in scope up to 1000hz.
- And much, much more!
FAQ's and Help
Q) Can i Remove the OEM SENT Map sensor
A) Yes. See the Manual for the kit here which explains how to change the Map sensor from SENT to 0-5v
Q) Do I control the OEM Intake Flaps?
A) Yes. This is set in Output Functions – Fan7 (Intake Flap). It's controlled Based on RPM vs Manifold Pressure.
Q) Do I control the OEM Exhaust Valves?
A) Yes. This is set in Output Functions – Fan8 (Exhaust Flap Control), Its controlled Based on Load vs DriveMode so you can open only in Dynamics mode.
Q) Do I control the Exhaust Cam Lift Solenoids?
A) Yes, we activate just the Power CAM.
Q) How is the OEM Coolant Switch Pump Controlled?
A) This is found in Output Functions – Fan2 (Coolant Switch Pump). It's controlled based on Engine speed and Coolant Temp.
Q) How is the Electronic Blow of Valve controlled?
A) This is found in Output Functions – Fan5 (Turbo Recirc). It's controlled via Throttle Angle, Manifold Presure and RPM.
Q) Do you use the OEM Egt sensors on Euro Models?
A) We don't support these currently
Q) Can I install different in tank pump?
A) Yes. The Syvecs communicates with the OEM Fuel Pump Ecu to allow PWM control of the pump so it can be adjusted to suit your new pump. This is found in Output Function – Fuel Pump - Fuel Pump PWM.
Q) Which of the original features will now not work?
A) Adaptive Cruise control and LIM, we only support standard cruise control.
Q) Can I use the OBD port still to log, read codes and clear them on other ecus on the car like ABS?
A) Yes. Via the use on VagCom.
