Im in the process of megasquirting my 78 280z but there is a couple of issues. Im trying to get it to run fuel and spark. So I tryed to flash the MS unit with the MS2/extra firmware but for some reason it wont work. I followed the instructions. Selected the correct COM, Turned off the unit, put the jumpers on, Turned on the unit but I always get the same message. Anyone know why I am getting this message? I can no longer communicate the the MS unit.
I followed the instructions here:
