The process involves sending your ECU backup to Chaos Calibrations, who then build and deliver a custom tune for uploading.

Available features include adjustable rev limiters, throttle response adjustments, thermostat setpoint changes, and options for pops and bangs or launch control for manual transmissions. The tuning process supports Windows laptops or Android devices with a K+DCAN OBD2 cable.
