Those with Tein EDFC experience

so i just installed the EDFC today but when i turn on the car to give it power it just gives me a beep and does nothing else. looked to the manual but it said nothing about it just beeping once and nothing

never mind i suck, found the problem. i have another question though, is there anyway to have the presets saved when you turn off the car since the memory gets deleted every time?

I’m pretty sure there is a constant power wire.

Correct constant pwr, key+, lights, ground.

ahh i see thx
