Unitronic Stage 1+ Performance Software is precisely calibrated for use with 93 octane / 98 RON fuel. It is the performance upgrade that will result in the most gains!
Unitronic Stage 2 TCU Performance Software is required to run Stage 1+ ECU tune. Performance Software for your ECU Box Code is subject to availability. 2019+ models may 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.

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.)
Full Staged Software Suite
Includes all Stage 1+ tune variants and all lower software stages as well.
Rolling Anti-Lag (RAL)
Unitronic is also proud to announce the addition of Rolling Anti Lag (RAL) into these new FLEX enabled calibrations. FUNCTION USAGE: Turn cruise control ON, but not activated. Hold down cruise control stalk downwards (decrease speed, -), then go wide open throttle WOT. You can do this with your left fingers, while both hands are on the steering wheel with ease. PRECONDITIONS FOR FUNCTION TO BE ACTIVE: 70degC coolant temp minimum threshold, more than 1000rpm engine speed, more than 30kph vehicle speed, and more than 45% throttle position. The function will be activated for 6 seconds maximum and can't be re-activated for 15 seconds refresh time. This function is very hard on the engine and its components - IT IS NOT FOOL PROOF. It's easy to melt an engine to the ground with it. Use it wisely and at your own peril.
Installation
Flashed directly through the (OBDII) Diagnostic port of your vehicle (15-20 minutes).
