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!

  • Review shared from Unitronic Stage 1+ ECU Tune (15-21 GTI)

    Awesome!!!!

    I just purchased the stage 1+ and I'm freaking in love! It had made an insane difference without taking daily driving abilities away. Shifting before 3 grand is smooth and easy and issues with just cruising. Then then you drop two gears and floor it and it pushes you back in your seat! I highly recommend the unitronic tune! Super easy to install and you're set!

    Buy It!

    Kicks ASS!! Simple but powerful!! Easy install and what a difference it makes. I actually get pushed back in my seat when boost hits at 4k. The low torque is incredible and the daily drivabiltiy is awesome!! Ive had the tune for 6months now and will be upgrading to 2.0 in a month or so. Just waiting for the downpipe..You can upgrade for cheap to from 1+ to 2. Just by the cable so you can do it yourself.

    I would high recommend this upgrade. and/or the 2.0

    amazing

    You WILL NOT regret purchasing this software for your MK7 GTI. It makes the car scary fast. Running with stock tires and engine/trans mounts makes it difficult to get the power to the ground without spinning the tires through 2nd and even third gear if you are on rough or wet pavement.

    I was a little worried about how the stock clutch would handle the increased power but so far so good. Will just have to cross that bridge when I come to it I guess

    Night and day!

    Low end torque is unbelievable, everyone who drove it went crazy!!! Top end is almost stock ish but that power from a dog is incredible, the car feels soooo different.

    Must have

    I was honestly getting frustrated with the lack of power in my MK7 GTI, to the point I was looking at M235’s. I decided to try out the Stage 1+ tune in hopes of falling in love with the car, and well, it worked. This tune completely changed the driving dynamics throughout every gear. Now the GTI isn’t just fun around corners, but can hold its own in the straights. Fall in love with your GTI again, buy this tune!

    Must Have

    I loved my car when I first bought it, but the fun eventually wore off as I got used to how it behaved. This completely changed my GTI, and I have fallen in love with it all over again. This is definitely a must have

  • Review shared from Unitronic Stage 1+ ECU Tune (15-19 Golf R)

    Must Have

    This is how the R should have came from the factory. If you're looking for gains, better response, and more smiles then this is it. Stage 2 next for me.
