I just installed my race ecu and harness on my 13 ZX10R, but I can not get the ecu to read or write using the calibration tool. I reinstalled the driver and the software using the manuals instruction including changing the port to match the port on the laptop and I still can't get it to respond. The bike rides fine so I know everything is installed correctly. I am running Windows 8 and am wondering if that is my problem. Is anyone running the calibration tool on a Windows 8 laptop or have a possible solution to my problem? Thank you.
