would safc help N/A?

[1987HondaAccord]

hey,

basically i'm wondering how much something like the safc would help gas mileage or performance of a NA car. I don't plan on going turbo, but i'm still wondering, since they look pretty interesting. would the safc 2 work even though our cars are OBD-0? or would it be necessary to convert to OBD-1?


thanks in advance.

I am not sure about obd0 working with the safc, but unless the motor was built (pistons, manifold, header, throttle body) I wouldent bother with an safc. You can only tune so much with a factory motor.

white/yellow--------red (power input)

connector "B"

red/blue------------blue (oxy sensor "B")air fuel
ratio seen in voltage.
can be seen on sensor chk.

connector "C"

white/blue--------------(ecu side=yellow)

safc2 works on the third gen. only problem is getting a rpm signal which you can get off the gauge cluster or the tach out of a msd etc.the rest of the wires are tapped off the ecu harness.

made a difference with just the initial setup on my car but then again my engine is highly modified. I have yet to dyno tune with it though.

im guessing the best benefits of this piece will be seen with extensive engine mods and proper tuning.

[1987HondaAccord]

so with just a cam, header, intake, and coil the benefits would probably be minimal right? i'm just thinking it might be fun to 'play around with', but maybe that's just silly.

would doing an obd-1 conversion be more cost effective?

[AccordEpicenter]

yeah itll work but its only somthing to tune with, so unless you have dyno time or a wideband o2 its tough to say wether you should add or subtract fuel. Remember, adding more fuel doesnt automatically make you go faster, youd need significant mods to make it worthwhile at all, like a header, full exhaust, cai, bigger TB, possibly head/cam work, maybe b16/b18 intake mani, or turbo etc... i had it on my car when i was n/a and it didnt help me too much to play with the fuel before i was boosted.

[guaynabo89]

remember for enough dyno time to set it up correctly will probably run you 200+ on top of the afc.

obd1 ia a little complicated as far as wiring plus you'll have to know someone that can modify a obd1 dist to fit.

Hey epicenter. I have an Autometer Air/Fuel guage but, I'm not exaclty sure how to install it or for that matter if it's even able to be installed in the cars stock form. Do you have to have a wideband o2 sensor in your exhaust first before you can monitor with the guage? I know that our cars have an o2 sensor but, I wasn't sure if it's able to work with the guage. If it is then you should be able to look at the guage while tuning to see whether you're lean, rich, or perfect right?

[A20A1]

When I tapped my Autometer A/F wire to the carb motor O2 Sensor it didn't work. I had to drop the connection to the control box and hook the O2 Sensor directly to the gauge. It may be different on EFI motors though, since you can tap into the ECU perhaps.

[bobafett]

i found the same thing mike. when i hooked up an autometer AF gauge the signal was wacked out, i got like 12 bars lit at a time hehe so it was useless. ;-) i never tried running the sensor directly to the gauge though, thats not a bad idea (since the DC has an extra spot for it!)

[w00tw00t111]

So Mike, Before I convert to EFI If I want to use the guage what you suggest is running the wire coming off of the 02 sensor in the header directly to the guage? That won't interfer with anything I would imagine since you are running it like that.
