I've just been through the igniter change....out of the box, the procom is very different from the original triumph part....it does not tolerate low voltage, so a marginal battery will need to be replaced, and its default map is much different than that of the triumph part....since I've been macintosh all of my computer life, I'm still looking for a gearhead/pc laptop user to aid in the installation of a better map - but on the bright side, it now starts and runs!
