I'm using my desktop right now I need a usb/serial adapter for my laptop. I've tried all the different com port settings and nothing. When I open up the ecu 32 program it says that I have to enter license and when I do (I'm using the license included in the read me file for the new software) and then it says verify if there is an engine control unit connected to the proper port. I'm beginning to think the controller is dead. When I use the Super Fueler 32 program and I try to get data from the controller I get this message "failure to connect to attached controller (no response)". Anyone know of a way to test to see if the controller is working? I'm going to uninstall and reinstall the software again on my computer and see if that does any good and pick up a new serial cable as well.
