"with a off board you can scan but its all dead info, like the cars not running, but it will show everything your scanning and values"
So you cannot scan? You're saying you can scan but itll be like cars off so technically you cant scan.
U asked if i had another car to test i replied earlier that yes i had to use my Daytona500 to tune the top swap.
I need the obd2 port to work for inspections AND to scan and tune again this is going to be a build car why an offboard is ruled out as not an option at all, whats the point in having an offboard when you can't scan the car with it?
