Who said the xcal3 doesn't work ? ? It really depends on ur budget, get the livewire if you plan to use it as a digital gauge, pretty much all its good for and theyve worked out almost all the quirks with the livewire nowadays as compared to when they first came out. If you just wanna tune, n leave it till next time, xcal3. Both great products
I just did mine beacause I had the sct1, I also wanted the sct 3 or the livewire but Greg at ret explained that they are having problems with the new ones already. Or maybe the tuner are not sure how to use them?? I trust greg though so I followed his direction and I am very happy with the tune.
I too need to know what is better. The Livewire itself looks enticing of course but if it isn't going to work as good I'd rather spend my money on the SCT tuner that is worth it.
Xcal2 - its' been tested/proven and it has plenty of capability. The LiveWire took forever for SCT to get all the bugs worked out, if they even have. The Xcal3 is still too new.
