Yes,
My Livewire just sits in the closet now.
All I used it for was to reflash the PCM.
SCT didn't charge me anything for the tune though.
I told them I wasn't happy with the stock powertune
program that came with it and if they couldn't supply me with something acceptable I was going to return the Livewire to Jegs.
I also have an Elmscan USB interface which is compatible with all the
PCM protocols and hooks up to a laptop.
There's a bunch of free programs such as Scantool, OBD2Spy, and others plus pay software such as ProScan, PCMScan, Digimoto which scan DTC's, clear codes, give real time readings and do logging, show if OBDII monitors are reading ready, do 1/4 mile times and speeds, simulated dyno pulls.
I've used these on my other ride-97 Camaro Supercharged LT-1 vert along with LT-1 Edit allows a lot of changes and is similar to what SCT would use to write a tune.
But on the Lincoln I'm happy with just reflashing the PCM and driving it.
