The new kit comes with the EFI reflasher so you can make minor changes to the ECM yourself along with Tims advice and a laptop , keeps you from having to send your ECM back everytime you need to make a small adjustment for a different mod . Like me for example I have to send Tim my computer to get it reprogrammed for gears when I get them in a few weeks . If you get the EFI flasher kit you could just hook up your laptop and do it yourself .
