You do lose the ability to datalog with the Cobb, although the JB4 is still able to do it although it is slightly less advanced in that manner.
I got it now!
Thanks for your input.
I used to drive a 1992 3000GT VR4 and back then I was adjusting the boost mechanically but now everything is done by electronically... hence confusions came across...
I am going to order JB4 by end of this week. ^^
