Major Idle prob..help!
True...I agree. I personally still believe it's a vacuum related problem. The MAF was rescaled pre turbo with the ETS intake and idled OK. Like I said before, I swapped a guy for an HKS RS filter over the k&n and it helped idle. The k&n just didn't want to idle at all (pre turbo) I now have the k&n back on and plan to swap that out with some other filter to see what happens.
All mods were on the car except the manifold and turbo. I know my stock IX bov starts leaking at a measly 8 psi..it's minor but leaks none the less. I need to grab a new aftermarket one, was looking at the works or the aps twin vent.

It's odd that the stock piping makes that much of a difference.
That's what I heard too, but 8psi isn't near 25. I guess all are a little different.
The stock piping makes such a big difference another local guy is ditching his ets pipe too bc his idles sh**ty like mine did. I'll post up if his helps his idle issues too.

You think maybe you're dv is just bad or something? Has to be. That's not even stock boost.

Well bob you know me, its AMS or bust, I would call them, explain your situation and see if thier intake would be better, I personally think it will fix your problem since AMS is well... the best, Ill call you in the morning and we will see whats up with the bov.
You know. I'm going to re-vive this. It's eating at me that I am running a stock rubber intake hose. There HAS to be some solution to get the ETS intake pipe to create vacuum and idle right. There's got to be hundreds if not thousands of us running it on an evo.
Anyone have any suggestions?!? I'm going to start messing with it again. Everyone says MAF scaling. It was scaled. I could post up a snap shot of the table if it will help...

OK. I got a decent warm idle. Mitsulogger is telling me to reduce fueling by 7%. (it's prob more but i'm taking baby steps) My car idles in the 50 and 75 hz cells. Both units of air in those cells is very high according to the "maf scaling how to's". I did my calculations and this is what I'm looking at. This is what the maf scaling is NOW.
HZ - Units
19 138
25 146
50 164
75 177
This is what my calculations from mitsulogger with the 7% decrease and the 140 adder factored in for the 50 & 75 hz cells.
HZ Units
19 138
25 146
50 142
75 155
Anyone think it's ok for the maf scaling to drop from the 25hz cell from 146 down to 142 for the 50hz cell? My car never shows it idling in anything less than 55hz so I wouldn't think it would matter.
After flashing this to the car, the car actually holds vacuum! Around 15-17". Up from a measly 10". Something I notice now is the car will randomly go lean when cruising. I'm going to keep this flash on the car for a while to let the trims adjust themselves, then re-log. This look like I'm heading in the right direction?

I think i have your answer bro. How much distance do you have from the turbo to the maf.. Alot of times the larger compressor wheel near the maf can cause flucations and the Maf reading inaccurate and very unstable. just try a loger pipe between the maf and turbo. if not that id start looking in the idle stepper lookup table
It's just the distance of the ets pipe. So not very long. I would agree with your assumption. If you look at my air volume it's all over the place. It even goes to 0 (which obviously isn't possible) but it's never stable. It's always fluctuating dramatically. I have an AFI intake that's made for a NON ACD car. I tried to make it work because it's longer to test your theory but then the recirc won't fit. It's not long enough. I may try to make it fit again to try that out.

Yeah I believe the rule of thumb is you want the maf 4 inches away for every inch of inlet you have... like 3 inch inlet turbo means you need the maf a foot away. you can often times get away with less but still thats just a general guideline. I figured this out when I had TPS codes and could not figure out why......it was cuz when i would let off the gas after boosting like 3 psi the spinning wheel would draw air over the maf so to the car it looks like im letting off and air flow is increasing hahaha
Anyone else have any suggestions. Such as MAF scaling solutions. Some ppl told me they left their stock maf scaling with the ets intake. Anyone do that? It doesn't seem like that makes much sense bc of the air volume increase w/ the open element filter. I'm going to try to mock up a "longer" ets intake pipe just to see if it's the turbulence from the comp wheel on the maf sensor.
I have the same problem with the HKS intake. Scaling the MAF, Setting ICSV vlause, raiseing idle RPM.....Nothing solves the rich stall. GRRR
I have revolvers and an FP Green if that helps.

Try putting your stock intake tube on with the maf and hks filter. Your recirc pipe should fit up just fine. Post up back on here your results. Me and another local guy here had the same problems, both went back to the stock intake tube and she's perfect.....less a few hp.
OK. I am officially loosing my f****** mind with this intake problem. ETS was nice enough to send me a 6" couple to try to move the MAF further away from the comp wheel to rule out any turbulence. It did absolutely NOTHING. Same sh*tty f-ing idle, only 8-10" of vacuum. If you just tap the gas pedal it trys to stall. WTF is up with this thing??!?!?!?! I'm going to start exploring different intakes, problem is...I don't have them. Seems crazy to buy 10 intake setups to figure this b**** out. HELP!?!?
