I think I rember seeing something labled as ecu memory when going through all the schematics and pinouts during my wiring. But now I cant find it.

My car runs great, but seems the ecu is reseting everytime I shut it off.

Am i crazy or did I really see that a 12v power needs to be wired in to keep the ecu memory? Whats the wire color code if there is? RB25det SII

Thanks

the ecu does need a 12v constant for the KAM (keep alive memory), ill see if i can digup the pinout.

krayton, you have it somewhere? i know you had to rewire yours for the EMS.

Doh that's actually for the RB26 but the RB25 should be similar.

yea, I found in the rb25 SI schematics pin 58 (white/black) is wired into battery, I have it wired into ignition now. Is this the wire that should be getting constant 12vdc (with ignition off).
