From what I have read one of the major advantages to the JB4 is that it has the ability to use the ODBII to gain access to information about the car. I think the quote below from their site explains it. As far as I know there is no wireless interface that the JB4 can use to get this information so to connect it you would need to run the cable.
I think I read somewhere that if you don't use the ODBII connection you would be limited to MAP 1? I will try and find the discussion where I saw that so don't quote me on that yet.
"Unlike other tuning systems the JB4 includes a fully programmable CANbus system, upgradable firmware, and data logging capability. CANbus allows the JB4 to take in to account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those in to the performance mapping. It can also read/delete fault codes, incorporate unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lucubration, and drop to a low boost map if the engine starts to over heat, run lean, excessively knock, or over
boost."
Snipe I got all mixed up too on the semantics of it all.....do yourself a favor and get the jb4 connect with phone app.....as Terry sez you have to run to your obdi to get full advantages of the jb4 along with hooking up the 2 fuel wires..... im old used up and it only took me a lil bit to run the obdi wire from the lb4box to the obdi plug in the car....theres a big rubber grommet that you push the wire thru...no biggie
I was all mixed up on this...YES you must hook up to the obdi to get full usage of the jb4 end of story ....Wash
