Hi, Yes you can attach the car to your laptop via this cable and the eurocharged software, Eurocharged can even do it remotely for you direct from the states or you take the ECI file from your car using the software save that to your computer send it to eurocharged and they send you a remap and you flash it to your car. Its all pretty straight forward provided you follow the procedure carefully.
I also have a 64mmEurocharged Supercharger pulley and SL55 airboxes for sale both for £500 or £350 for pulley and £150 for boxes. Them with a remap would transform your C32.And cable thrown in FOC
