[Florida240sx]

Went and got a stock ECU that matches my ecu code and put it in today...With my key turned the safc didnt' turn on......I was confused....but Started my car and it turned on and works.....Was letting the car warm up so I could et timing it idled for about 5 minutes, when my dad aske dif I wanted to go out to eat. I said yea and turned off my car. Came back an hour later and my SAFC is still turned ON??????Key is out of the ignition and SAFC is still lit up.Everything else is turned off. radio, gauges, mdm techtom, etc. But SAFC is ONSafc gets it's power through the ecu so what is going on here??? What do I need to check? Didn't drive the car but revved it to abotu 4k and it does perfect...Thanx...

No help??????? ECU has constant power where the safc is...how is this??? What fuse/relay do I need to check??? Or is it something ignition related??

Figured if it was ignition related then my gauges/radio would be on also....

Perhaps it's on the wrong ECU pin? What diagram did you use for the pinout?

Very strange that your ECU is getting constant feed that way, though.

If you want I can come and let you look at my SAFC or maybe you can use it to troubleshoot...

And I can use your wideband to tune my car

It's got to be the ECU. Got home today and the harness with the SAFc has a plug. plugged it back in and the SAFc turned on. I disconnected my ECU and put in my enthalpy. Works like it should. Went back to my other ECU and safc wouldn't turn on at all.......
