So far i haven't really figured out VE either. But I'm getting a fairly stable AFR at idle now, and cruising. I wrote my whole VE map with 128 to try to avoid any kind of inconsistency at low load and idle. Went out and got the K-value again this way, leaving the latency alone at 600uS. I imported t...

When I start adding fuel, will I exclusively add values over 128 to add fuel in the RAW table? Meaning, Will i need any reason to ever use any RAW values under 128? So, when adding fuel I should focus on theoretical AFRs on that filtered view and adjust VE until the actual AFR reaches the theoretica...

While narrowing down the K / lat Do you recommend leveling out the VE map to 128? When I start adding fuel, will I exclusively add values over 128 to add fuel in the RAW table? Meaning, Will i need any reason to ever use any RAW values under 128? So, when adding fuel I should focus on theoretical AF...

I'll keep the intake pre-turbo, don't want the hasstle of setting up a blowthrough setup anyway. The B14 MAF does seem to play best with the car. I adjusted "Filtered values" in the fuel map for 0 in the closed loop area. The IDLE is settling around 14.7 now, but light cruising under 3k is...

Also, Should i have the MAF on the intake side of the turbo (before the filter) - currently this way
OR
Should i put the MAF in the coldside piping closest to the TB?

I feel like I have it VERY close now, I'm using the DE binfile with the S14 Fuel Map for DET RAW Value is zero in these areas. o2 unplugged. crusing 4th gear - 3k RPM - 14.7 STABLE Cruising below 3K is ~ 12.0 Idling gets around 11.0 This is a latency issue? Meaning i need to lower uS value? Or shoul...

Have been digging into the forum for info, found a lot of helpful things that the nistune documentation didn't cover. One question I have about latency values that I found. Is it still requred to convert ms to microseconds? Those numbers you mention are in milliseconds. Nistune entry is in microseco...

I've made sure the BOV is nice and shut, in fact it's been surging a bit. But when in it does BO it gets rich as suspected. Guess that'll have to do until i route it into the intake. When i said i was using s14, i really meant b14. All these acronyms! lol I just opened my OJ600 binfile and the VQ ma...

It's a g20 with avenir motor, stock g20 MAF (I'm using the s14 280hp MAF setting in nistune, this may be an error, I may have to use the 250hp DE setting on there..) The ECU number is 0J600 Manual o2 feedback flag is off. The 2 other areas in question: I have the valve cover ventilated (usually plug...

I would not use that s15 map, lol! +100 fuel at idle, Bet it would run a bit rich.

I got the car to idle now, but I'm trying to get the Kvalue and Latency set. I'm getting pissed at it because everything i try it's not getting smooth. I've read through your quick start guides and it makes it sound easy, but Mine doesn't feel to be going as nicely. o2 is unplugged: K Value: i drove...

the voltage is actually higher with the car on. I did some reading in the FSM and that's actually an acceptable voltage value. The measurement I was getting online was something to do with the current through ground. Boost leak tested to 11psi, fixed a few leaks. Somehow my ghetto IACV route from th...

What i've got so far. Hooked the wideband bung on and in the car. It idles at 14.7 with the throttle in for a bit, then starts leaning out. So I push the throttle in a bit, the fuel map cell moves WAY over to the high load (+22 fuel value) cuts out a bit and returns to 14.7 to repeat the cycle again...

Front o2, not displaying voltage feedback with ignition ON, (does it?) Also will not display when car is idling very poorly. ECU problem / Wiring problem / Bad o2? I've tried the JDM o2 sensor as well, no luck which makes me think it's something besides the sensor. I had to extend the wire, the whit...

Project link: http://www.arrides.com/ARR/forums/index.php?showtopic=5592 Right now the car starts up, ONLY if you slightly push the gas pedal in. It will idle fine, smoking a little fuel smoke until you let off the pedal, then it will die. It pulls 20inHg during that time. Here's what i'm doing righ...
