okey so here's what i happened i don't know why but it did

before i purchase the ecuedit basic i already download a free trial software.then i purchase it and got my registration key which i enter on the registration column and the external sensor doesn't work.so i decided to uninstall the ecuedit software and download a new one.guess what everything work's and it will ask you on the download if you are using a extenal sensor if "yes" check the box and it resumes downloading.to connect using your LM1 or any other wideband connect the serial cable that goes to the wideband unit and the USB cable on your laptop you can choose which ever COM port you want same with the tactrix cable and click the ecuedit icon on your desktop
click the subaru/mitsubishi icon and click on the external sensor,choose innovative SDK for LM1/LC1 users then click the sensor type and choose one of the following available sensors then restart the program.
click subaru icon-connect to ECU from there you can choose which software you want to data-log if you wat to use the graph right click on one of the colored box on the right and choose parameters.
hope it help's for the beginners like me.
