Well to start off I recently traded for a Blacktop Sr'd Coupe. I've had it for about 2-3 weeks now, and everything has been running Cherry untill lastnight ! Which is when I messed up ..

I'm having Apexi SAFC issues now.

The previous owner was running a z32 MAF, and it went out on him so he swapped the stock Sr on back in. He said the SAFC reset aswell when doing this, so I would need a re-tune? But if it reset it shouldnt effect the car at all should it? I've been DDing the car for since I got it with no problems.

The IN/OUT setting, from what I'm reading in the manual it says it's sensor numbers, and [Pressure is the menu selection]

He had the IN/OUT set at [01,01] and lastnight I accidentally hit one of the buttons and changed it to [09,01 !] The car instantly bogged and shut down. I then put it back to [01,01] And it ran fine the way home.

So this morning I went to the store and started the car up and it was bogging again, aswell as had a rough/spiked idle. It shut down too.

SO like an idiot I started second guessing myself thinking maybe I was supposed to put it at [00,00] instead? So I tried it and the car ran fine.

Later that day It started bogging/dying out again and I limped it to the gas station. I put it back to [01,01] Which I'm 100% sure it was when I got the car !

The car runs, but it boggs/draggs when I'm around 2-3k rpm, and just dosn't feel right at all. It's not peppy like it used to be. And when I stop the idle drops down to about 500? Then goes back up to around 950/1k.

Could this mean I need a re-tune? Or could I just re-set the controller? I don't plan on making anymore power/upgrades to the motor any time soon. I just want everything stock/factory and I'm happy with it like that.

I just don't want to drive/make anything worse than it already is.


I'm hopping if I just reset the controller, than everything should be fine because I'm running everything stock anyways. And want no use out of the controller.

I will take it to get tuned if I must, but thats a last resort. :/

Any help from my wise burglars?! Thanks in advance.

Sorry for the long Sob story .. Just really want to figure this out, and not mess anything up.

Theoretically, if you have the stock turbo/injectors/mafs/no safc, shouldn't it just run like stock again?

The SAFC is still wired up, and since I pressed the wrong button hasnt been reset. Should I just reset it?

seems like the best thing to do is cross your fingers and reset it and hope it works.

So I found a video on my phone of the car when I first got it, and the setting was actualu [01,02] ! Sounded good when I started it, but it was already idled from earlier. So I'll try a cold start when I get off and well see.
