Re: ECU interface for GSXR 1000 K9?
Well if you don't follow the schematic you are given how do you expect it to work?
Connect the red wire AND brown wire together,then (after) the red/brown join connect the 1kohm resistor and terminate that to the pin 29.
Connect the usb R232 5V cable to the PC,set up the com port correctly,and then connect all the wires to the ECU.
Finally turn on the ECU by connecting the +12V and ground to the ECU and you should be fine
