safc and wide band help?

[4seasons69]

ok so the rpm display on my safc doesn't work. it hasn't worked since I installed it. ive double checked it a couple times and i'm pretty sure I have it wired in right. i'm wondering if this could have an affect on how the safc will work?

as for the wideband I wired it in and it works but now I have a check engine light on.

so I'm wondering if someone can help me a little bit. any suggestions will be greatly appreciated. thanks

If your RPM doesn't work, you're missing something in hooking up your SAFC. Check your wiring again, specifically the tach wire.

For the wideband, the wiring is independent of anything that would cause a CE. Check what the code is and go from there.

my safc I wired in the rpm wire once then rewired it in again and it still doesn't work. maybe i'm a retard. as for the wideband the directions said something about wireing resistors somewhere or a check engine light would come on. something about a code for the heating wire or something

Are you using the wideband in place of a stock o2 sensor? If so, then yes, that would cause a CEL unless you take the needed steps to disable it.

Your S-AFC will not work unless the RPM is wired in correctly.

yes I am using the wideband in place of the stock o2 sensor and I tried following the directions on how to wire it in so it won't throw cel but I obviously didn't do it right. I guess I'll just search for more info and try going through it all again

I can help you with the SAFC hook up, I just put mine in my car...

Did you put a resistor in like mentioned? I have a resistor in mine.

[4seasons69]

yeah I put a resistor in mine but I wasn't sure what wires by the ecu to put it so I tried wiring it in to the heater wires on the narrow band connector and that didn't work.
