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 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.
