  • Engineered with Strict Industry Standards: 
    With over 10 years of experience in Bosch and Siemens engine management calibration, Unitronic is able to utilized its industry leading tools and equipment to assure a calibration

  • Extensively Tested Under Various Driving Conditions: 
    Development begins using its in-house engine dyno housed in an environmentally controlled cell; closely monitoring a plethora of operational data, utilizing industry leading calibration tools and resources. Additional validation and results comparison are completed using its in-house Maha Chassis dyno as a second step of product development. Beta calibrations are then tested in race and street scenarios, using multiple cars throughout the world 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 an OEM-like drivability and reliability.

  • Engine Temperature Protection (Rev Limit based on Engine Coolant Temperature): 
    Engine speed limit protection active under warm-up to prevent potential damage when coolant temperature is not within operation range.

  • Optimized Responsiveness and Drivability: 
    Professionally calibrated to improve engine response and reduce drive-by-wire lag. Optimized torque curve for more low end torque and faster turbo spool.

  • Optimized Smoothness and Driving Comfort: 
    Due to the large flat torque curve, the calibration offers a smooth operation under normal and hard acceleration. This results in linear acceleration with constant torque without low end torque peak that will cause loss of traction and uncontrollable power surge, at the expense of high engine speed power.

  • Optimized Maximum Output: 
    Unitronic development team delivers the maximum power output while staying within the operational limits of the factory components used. Specifically, this results in the highest engine performance without sacrificing the reliability of the engine, turbocharger, or other engine 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 under cruising condition for an improved fuel efficiency.

  • Speed Governor Removed: 
    Vehicle speed limiter within ECU is removed. (If automatic, subject to transmission rotational speed limit)
