im using a giga ware usb to serial adapter to load my ems on a windows vista computer and the computer isnt reading the sub port to ecu connection any ideas

 

what ems do you have??

 

make sure the USB to serial adapter is Vista approved. when I got my USB to serial adapter I made sure it had Vista drivers before I ordered it. once it's installed and working right you just treat it like a normal COM port. when you open the AEM Pro software don't select USB, select the COM port that the USB to serial port shows up as.

 

thanks that was probobly the problem and im using aem ems
