Stage 1 ECU
Description
Unitronic Stage 1 Performance Software is precisely calibrated for use with 91 octane / 95 RON fuel.
Performance Software for your ECU Box Code is subject to availability.
2022+ models require to have the hood opened during the flashing process.
Unitronic FLEX fuel enabled ECU Performance Software Calibrations are available for this platform allowing for seamless transitions between 100% gasoline to 85% ethanol and anything in between, without requiring an ECU reflash. This FLEX enabled Software is available for an additional fee and it covers all lower stages up until your highest purchased stage as well. UniFLEX Hardware is required in order to take advantage of these FLEX enabled calibrations. Please contact Unitronic or your local Authorized Dealer to learn more.
Unitronic Advanced Features (UAF) are also available for this platform. Thanks to proprietary ECU code, the Unitronic Advanced Features (UAF) Add-On gives unparalleled levels of control over Pops and Bangs, Launch Control Settings and Rolling Launch Control for true adjustability directly from the driver’s seat. If the vehicle is not equipped with UniFLEX, Unitronic's FeatureBox allows for seamless integration with the all-new UAF Control mobile app.
When purchasing this upgrade, please be prepared to provide Unitronic with the vehicle’s ECU ID, ECU Revision, VIN and Long Coding to ensure proper configuration.

Features
- Engineered with Strict Industry Standards
With over 10 years of experience with Bosch and Siemens engine management systems and calibrations, Unitronic is able to utilize its expertise, industry leading tools and equipment to ensure an optimal calibration; delivering maximum performance, while maintaining complete OEM-like reliability and drivability. - Extensively Tested Under Various Driving Conditions
Development begins using Unitronic’s in-house Maha Chassis dyno housed in an environmentally controlled cell; closely monitoring a plethora of operational data, utilizing industry leading calibration tools and resources. Beta calibrations are then tested in street and track scenarios, using multiple cars under various driving conditions. This engine calibration strategy ensures Unitronic Performance Software delivers maximum performance, OEM-like drivability and reliability anywhere in the world. Unitronic Performance Software is only released to its Clients once development is thoroughly completed in accordance to Unitronic’s strict standards. - Factory Safety Limiters Retained
OEM “fail safes” are retained within the ECU calibration. Close monitoring of all operation parameters ensures that engine operation stays within factory components limits, resulting in reliability. - Optimized Responsiveness, Smoothness, Drivability, and Comfort
Unitronic’s ECU calibrations are engineered to improve engine response and reduce low-end lag. Unitronic’s Performance Software has gained worldwide recognition and is well known for its broad powerband, with smooth power delivery, maximizing responsiveness and “area under the curve”, under normal and hard acceleration. - Optimized Maximum Output
Unitronic’s ECU Calibrators deliver the maximum power output while staying within the operational limits of the factory engine and drivetrain components. Specifically, this results in the highest engine performance without sacrificing the reliability of the engine, turbocharger, or other engine and drivetrain components. - Power Delivery Perfectly Optimized Throughout the Power Band
Aligned with the OEM strategy, the calibration is designed to offer a large flat torque plateau to provide a smooth and linear power band. Maximum torque output is achieved sooner and maintained longer which creates a broader torque plateau and greater area under the curve. This results in an improved acceleration and optimal engine operation. - Improved Fuel Efficiency
Optimized timing and injection in cruising condition allows for an improved fuel efficiency, under normalized driving conditions. - Ignition Timing Precisely Calibrated for Higher Octane Fuel
Engine calibration optimized to take advantage of higher fuel quality to extract maximum energy from the combustion. Therefore, when using a higher octane fuel, more power and better fuel efficiency will be achieved. - Speed Governor Removed
Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)

Stage 1 TCU
Features
- End-User Programmable with UniCONNECT+
Reflash your TCU from the comfort of your own home or garage. Within minutes (approximately 70-seconds to be exact on this platform), you'll be enjoying an entirely transformed driving experience. - Optimized D & Sport Modes
D-mode is optimized for improved performance while avoiding the tendency to target quick upshifts to higher gears. S-mode is optimized for faster acceleration in spirited driving. - Quicker Gear Shifts
Unitronic's TCU Performance Software calibration enhances the gear shift speeds making them up to 70% quicker. - Reduced Clutch Slippage
Unitronic’s TCU re-defines clutch engagement strategies to reduce excessive clutch slip in virtually all driving conditions. Users will notice the biggest improvements under light throttle driving conditions, but a more direct experience while driving full throttle as well. - Sailing Mode Disabled (EU/RoW only)
Disabling Sailing Mode keeps the drivetrain fully engaged instead of engaging virtual neutral and free-wheeling when coasting in certain drive modes at speeds between 55kph/35mph and 160kph/99mph. This provides the driver with a more engaged performance orientated feeling and driving experience. Sailing mode is inactive on most North American vehicles from the manufacturer.
