So I thought I might ask here first, long story short, I've been away for three weeks and left the car basically just armed and locked. About a week after going away the alarm went off and didn't stop being a pain in the ass til the battery went flat (My present to the new neighbours). Anyway, so I put a new battery in, but my question to the Almighty Guru's is whether or not after two weeks without a power source would my PFC have lost it's memory or not. From what I'm aware, it's much like a usb chip, in the sense that it holds data, but whether or not it needs a source to keep that memory I'm not too aware of. Shed some light anyone?

Cheers, Alex.
