So, I'm just starting to get into tuning. I want to make sure I understand some things before I jump into it.
So, HP tuners suite program is a free download that you can use to tune or just check readings in your car. However, you will need a way to access your car's ob2 port. This is the part where I'm kinda confused. Does the ob2 scanner only work for certain cars or is it the program that has the info for all the different cars ecu's? If I'm not mistaken you have to buy an obd2 port that works for your specific car and the reason that the HP Tuners port cost so much is because it can access a wide variety of different cars.
