SCT SF3 -- flashing question

I recently bought the SF3 and I am currently reading its instructions/pdf file. And I understand almost everything on it. But I do have a question. (because I was under the impression that you use it just like other DTC readers where you plug it into the OBD port, turn on ignition -not starting the engine- and follow its instructions on the screen)

USER ADJUSTMENT OPTION NOTES

Important things to remember


"Remove the fuel pump fuse and fan fuse before flashing. Be sure heater fans, windshield wipers or any other current draw is minimized during flashing."

I guess its not to use up too much of the battery? But do I HAVE to remove those fuses (if I have a new/good battery?) Mainly I want to know if most people remove the fuses before they flash, or do they just flash without removing anything? --I have nothing like extra speakers/bases/other extra power uses other than what is stock on a 98 mustang.

If the battery goes flat during the reflash, you will be taking the car into a dealer on a hook to get it fixed. Aside from that hazard, leaving the fuses in will have no ill effect. I do not run any accessories or illumination during the refresh which takes 5 to 10 minutes. I have noticed that only the instrument cluster and info center light do anything during the process.

yeah, those are liability warnings i'd say. i've flashed mine several times, no issue. to be on the safe side, i make sure nothings on other than the dash gauge readings, since you don't have much of a chose if that's on or off. the initial reflash takes around 5 minutes since the tuner gathers and stores your vehicle's info, and saves the stock file. then, it flashes the ecu. any subsequent reflashes take approximately 3 minutes though.

As long as your battery is in good condition you are fine to do it without removing the fuses.
I've probably reflashed mine 50+ times with no problem.
