I just bought a pfc and commander. I know you can use a wideband with closed loop if you have a dataloggit, but how important is that?

like i said, the tuning shop already owns a dataloggit, so do i need to buy one?

 

If you are not going to tuning your car or logging data, then it is not important at all. Nearly all of our customers do not bother with a DL as they have no interest in learning how to tune. Even the customers that do have the DL, the majority have never made a change the map, some have never hooked a laptop up to it.

 

You wouldn't need it unless you want to save your tune on your laptop
