Is The Safc-ii Compatible With An Automatic? (86 Gxl)?

 

Yes. And fix your car. You should be getting 250-300 miles to a tank.

LOL I know, but i dont know what to do for better gas mileage...i've already changed all the filters, plugs, wires...i just dont know what to do. oh yeah thnx for the respond, just ordered it (safc-2), should be getting here on wed. and going in on thursday.

 

hey, another question, should i solder the conections to the ECU or tap into them? which one would be better.
also, since i currently dont have the money for a wideband, could i just buy one of those simple afr gauge, to at least help me tune it a bit, untill i get the wideband? or should i just wait for the wideband?
thank you in advance.

 

I wouldnt use those wire taps/splicers that you can get. I have heard alot of rumors all over the place (off and on then net) that they come loose over time. You could solder them. I cut my wires and used spade connectors which saved me big time when my AFC got stollen. You could also solder and use spade connectors.

IF you use one of those cheapo a/f gauges. Dont try and tune for hp through out the RPM band. You will be working for a fine thread if you do that. Just tune it for closed loop and You can turn down the fuel a little bit through out the RPM band but I only reccomend it for the LOW Thrtl setting. WOT is scary without a wideband

 

Ok, thanx for the response. i guess ill solder them in. sorry to hear about ur safc. and yea i will try to adjust it only in low throttle with an afr gauge until i get the wideband. and to be on the safe side, i wont lean it out too much.

 

No Problem, Anytime.

 

another question. i just installed the safc-2 and it displays 20% open throttle, when im not even touching the pedal!! is my tps malfunctioning? if so, is it easy to instal, and if anyone has a price on them, please let me know.

 

^ Good thing that it was just out of adjustment

 

^Yup, i was already looking up prices too. phew!

 

no the safc learns. it will learn what 0% and 100% is.

floor it and let off a few times with the motor off and the key turned to the on possition. then turn the key to off... then back on and check again.. the safc shoud have learned the range of your tps voltage.


your tps being good or not and if its set to where it needs to be is another story. the safc does not know what the mazda tps should be set to... or if its even installed in a mazda.

test and adjust your tps per the FSM.

 

^^wouldn't pumping the gas pedal with the ignition "on" cause flooding?

 

witer remove the fuse like you would to unflood the motor.

or

take the car out and do a few WOT runs.

 

ooooo . ok. i'll do that today.

 

Yes, but, If the voltage it gets from the TPS is over 1v, the safc may say that your throttle is this % open. Since you set the arrow to point up. you are telling the SAFC that your TPS is fully closed when it read 0-1v and read fully open from 3-5v. It still has to learn within that range but a TPS out of adjustment could give you inaccurate readings.

Its a little easier then that. While the ignition is in the ON position (you should wire the AFC to only come on while the key is in this position) go to "Initial Setup" and keep your foot of the throttle for 10 seconds. Say 15 to be safe. Then floor the throttle for 15 seconds and let off. After that turn the key off. Doing this will save your set settings into memory. Turn your ignition back on and you should be set to go.

Nope, the fuel pump ONLY turns on WHILE the engine is TURNING. If the ECU gets a reading from the CAS basically saying the engine is spinning, then the fuel pump turns on. Not before. So turning the ignition to the ON position and pumping the gas wont do anything. You are safe and don't need to pull any fuses
