Features

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Speed Governor Removed
    Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)

  • Improved Fuel Efficiency
    Optimized timing and injection in cruising condition allows for an improved fuel efficiency, under normalized driving conditions.

  • 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.

  • Tune at Home Option with UniCONNECT+ cable!
    This platform is supported with Unitronic’s UniCONNECT+ cable, empowering you to tune your vehicle from the comfort of your own home or garage. The cable and associated software allows you to install, and upgrade, your new Unitronic ECU tunes, flash back to stock file in addition to reading and clearing DTCs. This is a perfect option for people who like to be autonomous or who don't have a Unitronic Authorized Dealer nearby!

  • I wholeheartedly endorse Unitronic's software upgrade for the Tiguan. Opting for stage 1 has brought me immense satisfaction, as it truly revitalizes the vehicle. The fuel efficiency has dramatically improved, with an impressive mileage of 28mpg on my commute back from work, which is quite remarkable considering I typically achieve around 21mpg at best.

    Furthermore, the noticeable increase in horsepower is remarkable. The Tiguan now possesses ample power for passing maneuvers, eliminating the need to forcefully accelerate as I did before. Without a doubt, this upgrade is a fantastic investment for your Tiguan, and I highly recommend it.
