quick question about re installing my Pfc...

[silviakid2790]

i bought a car that already had the PFC hooked up and running fine.. i want to put it on my other sr20...

here is my question... how long does the PFC keep a tune for without any power to it? if im not mistaken its about 2 days or so??

im going from a sr that had cams, 740s, gt2871r, to a stock sr20...will the pfc reset to the SR base maps since its been without power for over a month?

I thought they kept the maps on there for longer than that, don't they have ram built into them?

[Pank]

ram dies instantly without power. if it holds maps its got a battery backup or (more than likely) a non volitile ROM

you dont think the battery backup would last for over a month do you? lol
