ok i have searched and read about every thread on the ssq and the eids but most of them are pretty old.... well i orderd the ssq and the eids b4 reading more about them (stupid mistake maybe?) anyways im reading about how you cant vta which i dont really care about ill recirc need b. Just wondering with the eids should i be ok or with the recirc and eids should i b totally ok? like bogging stalling etc.... Thanks

I've been venting with the HKS SSQV for a while now with little problems. It tends to drop quite a bit in the RPMs during stops, but never stalls. I too have ordered the EIDS, should be here by Monday. Let's see if this fixes it. As far as you being totally OK with recirc and the EIDS, you shouldn't need the EIDS if you are recirc'ing.

 

True, if you wish to VTA then it's a good thing you purchased the EIDS. But if you plan to recirculate, then you won't need it.

On another note, if you do decide to recirc it I'll purchase the EIDS off of you.

 

yeah i really dont know what im planning on doing thanks for the fast responce guys im really worried right now i would like the sound its not worth having to struggle to drive the car though.... so i guess ill wait and c what it does if all else fails it should all b up for sale at the end of next week and ill just get a MR bov or something...

 

I have an SSQV and no EIDS and I don't have any probs with VTA. It stalled once, but that may not have been the fault of the SSQV. It does drop pretty low when you let off the gas and push in the clutch like stvbreal said, but it doesn't stall.

My car actually stalled a few times BEFORE the SSQV and my awesome dealer just said "could not duplicate" ... best backed cars my a$$.

 

Best backed cars is true for Mitsubishi. Only for all their other cars except the Evo.

 

I had setup my EIDS but i'm having problems........... The CEL comes on, my car idels at 2K RPM, and I got a fuel cut at 5 1/2. Also my brakes are a little mushey running VTA, it still stops good but u have to get on it. From what I'm told when the BOV recirc's some of that preasure goes to the Brakes. You can ask around and see what they say about the brakes and VTA. But if anyone hooks up their EIDS correctly please PM me and let me know what's up.

 

i want to know too

 

That doesn't sound right.. if the BOV is leaky at idle it will have trouble idling, and in turn may lower engine vacuum.. Engine vacuum is what controlls the assist to your brakes.. Sounds like you have a major vacuum leak somewhere.

High idle and fuel cut with the EIDS are a symptom of something not working right, basically your boosting the signal too much at idle (raising idle speed) and then "overrunning" the signal once the engine is under boost triggering fuel cut.. Both can result in a CEL since the signal is inappropriate for what the ECU expects.


Ok.. The EIDS works by "averaging" the output signal of the maf over a period of time.. there should be two adjustments, but generally the adjustment works by varying the time of the sample (as far as I can tell)

BOV's cause stalling because when you vent air, it removes that air from the equation, resulting in the engine running very rich, the engine tries to recover by removing fuel, but the BOV is now closed, and there's much more air again, so it goes real lean then stalls. This is a different symptom than what happens with Intakes causing stalling (in some circumstances it seems to cancel eachother out if you have both how's that for weird??)

Anyway, if you have a huge problem with stalling, you have to increase the BOV's spring pressure so it doesn't open as easily under engine vacuum (feel the output on the valve, at idle after the car is warm, if you feel air blowing out, adjust it until it no longer does) Unfortunately you may get compressor surge if you do that, so you have to balance it..

Here's the problem with the EIDS.. If you have a huge problem with stalling, you have to increase the setting on the EIDS until the dropout of the signal no longer affects the engine idle, unfortunately if the sample is too long, you affect your throttle response so the car feels laggy and a little unresponsive to throttle inputs..

Ok.. Now you got the whole story, use your judgment on whats worth it..

if you REALLY like the SSQV, recirculate it.. if you want VTA that badly, then you'll have to live with little problems.. VTA has very little to offer other than easier plumbing on some cars... You could run a blowthrough MAF sensor or Speed density conversion (either an addon unit or standalone) I doubt any of those would be worthwhile expenses just to be able to VTA.

 

thanks jack for the info it helps a lot im not really worried about VTA im more then fine with recircing it but i just want to make sure b4 i order the recirc flange if that will even help? i have read a few things of people recircing it and still having some issues..... and in the case of me recircing it thier would be no point in haveing the eids correct? lemme know thanks

alright Jack or anyone........... When hooking up the EIDS which wire goes to the car and which ones goes to the ECU

 

thier are posts that explain it and have diagrams do a lil search u will find it

 

I went over one post and it went over everything............ the only thing was that it said if it didn't work just switch the wire to the ecu and to the car. well I get a CEL with both, so that's why i was asking.

 

If switching the wire doesnt help you either have the wrong type of EIDS (Not sure which is correct) or you tapped into the wrong wire.. Unfortunately..

 

How do you adjust EIDS? The instructions showed it to be an automatic process.....maybe I screwed up the install???

If I rev the engine to over 5000 rpm and let it fall, the rpm's will go down to 500 and jump back up to ~900 all the while the EIDS light on my AFR is on

What my understanding of this phenomenon is....is that the engine has dumped accounted air in the atmosphere.....the engine doesnt know that hence it has responded with matched fuel....once the rpms have dropped, the engine is saturated with fuel thus causing the engine to lower rpm's as it cant sustain the presented air/fuel mixture.
