You should look what interface / hardware he hooks up on laptop and OBD of course. That is important, i think on that screen is just some dump tool to change mileage in dump.

No hardware, just laptop and usb to obdII connector
Couldn’t see name of program and couldn’t ask him
Thought maybe that was a certain software someone would of recognized

There is no such thing as USB to OBD2 connector, that is what i am trying to tell you all along. Thing what he plugs in is hardware interface, it can be simple and cheap as ELM327 (looking like cable which have OBD2 on one and USB on other end) and there is some software that works for mileage calibration with this "cable" but it is VERY limited and can do mostly asian cars.

What are you trying to achive anyway? If you want to do mileage correction no need to spy on his tool. Tools that are sugested before are proven to be good, AVDI, SMOK, diagprog4, enigma.... for cheaper and more limited solutions you can try FVDI and digiprog3

I want to be able to do mileage correction by obdII port on newer cars, 2010 and up to 2018 domestic vehicles since that what most people drive in US, mostly Ford Dodge Chevrolet Gm and some Toyota Nissan Mazda Honda Bmw
I have digiprog3 4.94 but only work on some older cars, and most I have to disassemble cluster, I want to be able to just connect obdII connector and change mileage easily like this guy does it
Thanks
