I thought that the cobb allows you to essentially dyno it anywhere anytime.. Based on ecu readings, etc. Plus you would then have access to clear codes and check settings on the go.
Whereas if you get a protune its always going to run in one setting you cant change and you also wont have the ability to read codes etc.
Also, if I got accessport couldnt I set several dyno maps and even get several protunes down the road I can interchange depending on driving conditions?
I feel like there are a lot of pros and cons to each. Or I just dont understand what the cobb accessport really is.
