If you had it connected correctly and the O2 caps on (they only fit one way) and it would not fire up I would say you probably messed up with the new map. Check the connector pins to be sure the are straight. If you use the "get" map it retrieves the map on the pcv. If you want to load a new map use the "open" to find the new map, click on it and then use the "send" function to send it to the pcv. Try again. Don't worry about the Pcv you can't screw it up - anything you do can be undone.
