dirt cheap ka-t setup (CRITICS and Suggestions are welcome)

Got my SAFC2 installed...had to adjust fuel at Idle +20%, now it idles 14.4-15.2and adjusted fuel at WOT -8% now it stays at 13.8-14.2

and adjusted fuel at WOT -8% now it stays at 13.8-14.2

I hope your not talking about WOT boost. You are going to pop your motor if you already didnt. i hope your talking about in vac/ cruise

[Romeo_rus]

yup i did... and I have already changed it... (needed to to do more research before doing than) put everything back...25 % TPS - 13.0-13.750% - 10.6-11.2Gonna go autozone tomorrow and check my compression (I hope I did not F**kED up the ringlands)

I doubt it's water, you'd be stuttering and jerking if it was enough water to change your AFRs.

Here's my .02

A motor loves to run rich. You can run just fine at 11:1 for idle AFR's. Granted you'll get lots of blow-by and ruin your oil and waste tons of fuel etc. But the motor will run steady and smooth when it's rich. They don't like lean. They hate lean would be a better description. My car wouldn't even idle at 16:1. It would start, but it was nasty. Which is why I thought your wideband may be F'd up.

When I did my S14 I had a rock solid idle at 14:1.

When I was initially setting up my fuel settings, aside from idle, I had EVERYTHING on the rich side. You won't hurt anything by running way to rich. All good tuners start rich and work their way towards 11.5 to 12:1 for power settings and 14ish for idle. Under vacuum the car will be all kinds of lean, that's fine.

Anyway, when tuning for load (WOT or more then 1/2 throttle) you want to make sure you're on the rich side. In fact you make more power at peak torque if you run richer then you usually do. Example, you make peak torque at 3900 rpm, from 3700-4100 I'd have it running at 11:1 AFR and then back to the high 11's low 12's after and before.

Does that make sense? It's early and I'm on coffee #1.

Now after rereading this thread is kinda sounds like you knew your AFR's were messed up but you drove it anyway If you wanna do yourself a favor you'll remove the BOV and plug that damn hole until you get all the tuning done. That way you know EXACTLY what's going on when you install it later.

Thanks WD, your comments as ALWAYS are VERY USEFUL!!!Gonna retune it again trying to get14.7 at idle13.6 at 25% of throttleand 11 at WOTI had a lack of intellegence (I knew that 14.7 is an optimal AFR, knew that I need to keep it richer than that) but I did not know about AFRs at WOT...I tried to keep afrs closer to 14.7 on the rich side
