I have an old serial interface from when I ordered HPTuners a while back. I am considering upgrading to the Enhanced IO MVPI Pro so I can do things like add a wideband O2. I currently have a cam'd LS1 and N20. Would I be able to do things like adjust air/fuel with HP Tuners like I would with a MAFT? If so I am not going to waste money on the MAFT, but if I think simply, the MAFT interupts the signal and I would essentialy be able to do the same with HPTuners and not need the "tirkc box". Any help would be appreciated. Thanks.
