i have Techstream already set up and working with the OP2.
i just thought of something; about 2 months ago now the dealership replaced my engine ECU under warranty as the remote starter that they had installed for me fucked a bunch of shit up

they still owe me $600

that could be why ECUflash isnt reading a VIN.
where would i go in techstream to set a vin for the ecu?
thanks.
