EFILive has little to nothing to over over & above hpt...hpt has far better pricing...far more support...Real Time tuning for no further out of pocket costs, we're now in the middle of beta for Ford products, etc.
just look at the credit system like tokens at a game arcade...you get 8 credits with your initial purchase to use at your leisure...pcm licenses are 2 credits, year/model licenses are 6 credits, 1 bar custom operating systems with real time tuning included are only 1 credit...and every type of license you trade in your "tokens" for are available for our upgrade credit system making unlimited or tunershop licenses even more affordable to the average user.
I talked to Kevin on the phone this morning a little bit about the software...the licenses are locked to the hardware so whomever holds the hardware has the power basically. But yes the software can be installed on several computers...I have it on my laptop & home computer currently.
