PV offloads the factory ECM image. Back that up on a computer just in case you lose the PV unit.
If you ever need to to revert back to stock map you can do it. It's supposed to be undetectable. Jamie can confirm this.
The PV will marry to the ECM info so even if you reflash the ECM with the original map the PV knows it's married to your ECM. You can buy a new license from DJ to use it on a different ECM if you sold your bike or have to replace the original ECM. It can marry to more than one ECM at a time also with purchase of another license, I think it can work with 2 bikes at once.
Jamie has maps for many pipe/cam combos. DJ has a growing list of maps on their site and a limited selection of maps on the PV itself. My biggest gripe about the PV is that you can't easily determine what the canned maps are built for - you have to open up each one and look at the info, very tedious.
