Power Fc Loosing Memory

[ff_driftz]

Good morning gents,

I have a RB26dett in a 'S' chassis and I am having power fc memory problems,

I plug the power fc in and go to the menu to turn the boost controller function off and do so, exit the menu and then re enter it to make sure it is still there and yepp all is good, but as soon as I turn the ignition off and turn it back on it has reset itself to out of the box settings again??

I have z32 afm's and no pfc boost controller so my car won’t start unless I change these settings? any suggestions? This has happened to one of my friends sr20det and he got some advice to put constant power to a certian pin from memory he believes it was the coil packs or so but not so sure and everything was fixed,

With the standard computer and afms the car ran fine.

Any one have this problem before I know there is some very smart people on this forum that can help, thank you and appreciate it.

That will be an issue with wiring to the ECCS relay. The ECU uses that relay to turn itself off after settings have been saved. The relay needs permanent 12v in not ignition 12v.

I have the same issue in my race car, it looses PFC changes if I turn it off using the kill switch because it cuts the permanent 12v power before the PFC saves
