So I brought a used AutoCal. I'll be using the same tuner to buy my tune (and send my logs to). So support should be fine
as well as linking the unit to a tuner.

I think with buying used I saved some money but complicated things. I have some newbie questions
until I receive the AutoCal then tune and hopefully some support from the tuner.

As I understand it the AutoCal has the original owner's VIN licensed to it forever?

I should be able to read my car as the second VIN on the AutoCal? Or do I need to purchase a VIN license to tune
my ecm+tcm?

My car would then be Read 2 on the menu (the original owner is Read 1 forever) ?

My stock ECM and TCM tune would then be what option on the menu to flash back ?

Can I erase all the tunes on the unit including the original owner's stock one to simplify things?


Thanks.. Sorry for all the newbie questions.
