Hi guys,

Been reading up about efilive for the last few hours, there's still some basic things which I have obviously missed. Well from what I have gathered I think it works this way but if someone can conform or set the record straight for me that would be great.

How does it work exactly? Is it just software which lets me interface my laptop to my car through the ALDL connector?
Can i read my LS1 ecu with this, edit it on my computer then flash it back?

What are these hand held units? do they let you mod the tune without using a laptop?

Also for every ecu I want to edit, do i need to buy a license? whats the difference between a VIN and a PCM license.

Also for the actual feed back do i need to use the EFI live scanning software, then based upon the data from that i go and make changes in my tune and flash back up.

Does it have support for wideband O2?
