Thread: safc II not pulling fuel

Setup is a rwd t25, maf blow through, 50 lb msd injectors, open bov, and open dump screamer pipe.

The wideband is showing 9.6-9.8 at idle which is pig rich. The car is dumping in so much fuel and cant burn it all my oil now smells like gas.

I deleted the pcv valve so its ran back into the intake pipe before the turbo.

My tuner told me to cut fuel back by -50% but it doesnt change the a/f mixture.

The cel is on and its pulling multiple misfire code and crank position sensor malfunction.

All spark plugs are carbon black and smell of gas.

Tuner says that i wired the safc II wrong but i triple checked everything and its wired right what do you thinks think would cause this?

did you go through the set up and make sure it was correctly setup for your car? new or used? if used did you do a reset??

Yes i reset it by initializing it and it everything back to zero. Setup was used on a 240.

I set it has hotwire for maf and set the cylinder to four and a arrow point up but didnt rev it for 10 secs i assume for the tps?

My tuner will be here thursday but wanted to make sure everything was working before he got here.

what car is this installed on? a 2000+ p11 or b15? bc the wiring is different for the rpm wire for one thing.

what else for engine management are you running?

are your injectors used? can you get them replaced or repaired or refunded?
is your wide band properly set up?

are you using the proper spark plugs? are they correctly gapped for your set up and heat range for the boost your running?

...problem, since you have tried the -50 value and still wont lean out then its either your:
injectors are leaking or bad, orings maybe (what i think its is)
or your safc is fried
or your low/hi throttle percentage are messed up




if it initializes then the memory is erased so then it should be good to go and all prior setting are gone.



okay, you need to reinitialize it. keep your key in the on position but dont start it. set up like u did above but you need to set your tps voltage by holding the gas pedal down all the way for 10 sec. then once the set up is done you turn off your car wait for the screen to trun of then turn it back on. recheck the setting then if they are good start it up.

to tune your safc with wideband your car needs to be under load as in no tuning it in neutral.

what is your maf ratio set up as? 1:1?
are you running a stock maf on top of your stock ecu

did you set up your Low Throttle tables corrections and High throttle tables corrections, correctly?

what is your Low/HI throttle Percentage distribution (30/60.... 40/50 ect...)

good luck

Car is a 01 Sentra SE.

No other management other than the safc II.

Injectors are used, was told they had 6k and bought them off of a member on here. Wideband is setup correctly.

Using bkr6e came pre gaped.

Injectors have new orings that I put on.

I will reinitialize it and see what happens.

Maf ratio is 1:1 and the calibration is 1:1. What should they be setup as?

No i didnt setup the throttle table corrections.

Not sure whats set up for the low/hi throttle precentage. What should it be setup has?

I reinitialized it and got to the sensor check and the throttle voltage is 4.110. It says in the initial setup to check the voltage closed and then open but its seems like is showing open but i haven't even set it up. It says closed should be 0 to 1 V and open should be 3 to 5 V what would cause this?

Look man, u wanna give me a call? I can help you, I have a 32 bit ecu in my p11 and run a safc2. I have a ton of shit I can just type to fix your problem but talking is easier. Pm me

pmed!
