Hi, when you disable the lift pump are you doing that in the fuse box.

Yes i am....i might add that in the past if i was in a hurry with the stock motor i would flash it with the pump running and still had no probs!

the reason i ask is that if you have a double fuse tap like i do when you pull the pump you need to put a temporary fuse in that spot ,assuming you tapped into one of the ign spots just a thought.

Yes i do have the double fuse tap its an air dog 150. I will try that tomorrow but like i said i usually just pull it to keep the pump from running! You think that fuse would cause it to not read the O.S?

Maybe try downloading the latest software, and then updating the firmware of the V2 unit.

Pretty simple now, just download both the V8 and V7 software from the "Software Updates" section of the forum. The EFILive control panel should pop up for you to update the firmware after you connect it to your PC.
