I think audio guys should know the answer to this question better than the suspension guys. So my friend and I installed the Tein EDFC Control unit today. There's a harness with 4 wires: red - accessory power, black - ground, yellow - constant power, green - illumination. We hooked everything up and thought everything was correct. Fire up the car and noticed the unit wouldn't turn on automatically. So we clicked the power button and the unit turned on. We had no problem using the unit to set the stiffness and use the pre-program feature to program settings. But once we turn off the power and turn the unit back on, the settings are gone. So basically 2 issues...

1. Unit does not turn on when ignition is on. I hate having to click an extra button every time I start up the car.

2. The pre-programmed settings are gone when the unit is restarted.

Thanks in advance!

Double-check your wires man.

Make sure and select your year from the pane on the right.

Maybe you got green and light green mixed up?

 

Sounds like you have an issue with your constant power to me. The constant power is what is going to save your settings in the memory. Recheck your wiring and make sure you have a true constant power source. Remember to use a digital multimeter and fuse everything. Good Luck!!
