Quick Help! Pull a fuse to load race tune after fuel pump out tune?

[ZOMBEAST]

Loaded my fuel pump out tune to pump out some lower octane fuel. Now I want to load the race tune, but when I key on with the SCT, the pumps are running and causing a low battery message on the SCT. Do I need to pull a fuse? If so, anyone know which one. Car is a 2009.

personally Id pull the fuse and put it on a charger, a battery dying mid tune can cause a lot of headaches

My X4 won't allow a tune change if the battery is too low. I think I had the same issue as you draining the tank. I recharged my battery and as soon as you start loading the tune, the pumps will shut off.

Yep! Just needed to get the battery charged back up. Apparently those pumps really drain the battery down. Thanks for the quick response.
