hello, i am new to using an mpvi1 and when you go to read a vehicle, most of the times it just brings up a drop down menu with all the ecu's listed on it and you have to select which ecu you have, then it will go ahead and read. Is there a way i can use to tell which ecu i have? Im having trouble identifying the ecu im hooked up to. I never realized there was so many until i saw that list haha, Thanks in advance guys
