AEM UEGO/afr

[scott90gsx420]

Ok so to bring this topic back from the dead..AGAIN

Picking up a AEM UEGO from a local guy on Thursday for 125 I'm happy with that price considering its never been used. So my question is whats a safe AFR on 93 pump. I don't have a logger and won't for at least a month or two as I am low on free cash and just got my new WB.

So I would like a safe AFR that would cause little to no knock. My profile mods are current if that helps. I know this topics been covered and I've looked a lot and still can't get a for sure answer.

Any help is much appreciated thanks guys.

Stock fuel settings until you get a logger to see how everything is running. That's what I would do anyway. However you'll prob. mess with the SAFC anyway so I wouldn't take it much higher than 11. 10.5 would be better as you are staying a little richer, just don't turn the boost up.

ok.. Ya i turned the boost up before my last WB die and turned it back down for a bit .. I will probably turn it up a bit just cause its how i am .. A also can't keep stock fuel settings anyways because ive got a 2g mas and a set of 560's in the car along with the other fuel stuff.. I raised my fuel pressure a bit to for safety but will probably turn it back down when i get this in.
On another note whats the best power source to tap into? I have heard several options i just wanna know whats better.. And where should i ground i don't wanna fry another WB(even though the last one is because the guy i bought the car from's stupidity).

Oh and how do i calibrate the damn thing ..

All of your questions can be best answered by reading the instructions.

I'll give you a few tips too.
1) Use only the length of wire provided with the 4 wire harness.
2) I have mine installed in my pillar, so I used an open spot it the fuse box under the dash, with a 10A fuse.
3) Take a few minutes to clean the paint off the area where you intend to ground.
