The PowrPro Black tuner uses the latest smart chip and accelerometer technology to continuously read the bike?s EFI delivery every time the motorcycle accelerates in order to optimise the air/fuel mixture for optimised performance. With its Continuously Variable Tuning (CVT) (patent pending) technology, the PowrPro black will yet again revolutionise motorcycle fuel-injection tuning. Even more so because now it includes the option for fine-tuning non-acceleration fuel via Bluetooth technology and a smart device based app.
