This Remote Cable Downshift Blipper is a modular system that is specifically designed to integrate with all Pro-Shift System Gearshift Control Unit's Downshift Delay and Auto-Blip outputs, with the exception of the Pro-Shift PSU System.
The unique patented design of this Throttle Blipper provides variable "blips" which are engine rev related to provide seamless, clutchless downshifting, all at the touch of a button.
Gen 5 just needs a flash to unlock the auto blipper down shift. Nels unlocked it on my ECU for free. FTECU wanted $300 to unlock it, plus the price of their flash lol.
