I know many people like the "whoosh" from VTA bov's, i myself do also. I know that it causes stalling problems and rich conditions which in the long wrong can damage the engine. Does the HKS EIDS fix the stalling problem AND the rich condition that is caused by running vta. I ask because the EIDS is only like $135, which would save money by not having to buy a stand-alone ecu like the AEM to be able to run a MAP. And yes i know that the easy fix is not to run vta.

thanks.

 

bump, anyone????

not sure but id assuime it fixed the ric h condition being that is what makes your car stall in the first place

 

I don't think so cause all it does is smooth out your idle.

The rich condition is caused because the MAF doesn't sense the air going back into the intake anymore, so there's that fuel going in, minus the air. So unless you recirculate or run a standalone, you'll always have that rich condition.

 

anyone with the EIDS have any input

 

EIDS works, I have HKS RS, SSQV, EIDS, and an SAFCII. The SAFC decel feature does not work with the Evo. I put the EIDS between the SAFC and the ECU and it works fine. Don't mess too much with the screw on the EIDS. I'd leave it as it comes from the factory. Also, there was a big improvement putting the RS intake on with the SSQV. I don't know what I gained HP wise but its very noticeable. I also bought the purple fin for the SSQV--makes a different sound when you vent. Deeper, more growly.

 

ok, so it does fix the stalling issue. What about the rich condition that a vta bov causes that can damage the engine in the long run????

 

can you use the SAFCII to fix the rich condition, or will you have to go with a stand-alone ecu like the AEM to be able to run MAP to fix it??????

 

why would running rich be harmful in the long run? the stock engine mapping is pig rich... eids also keeps the idle up along with smoothing it, so you will not stall. it's like... an automatic throttle at idle if your car wants to stall.

 

I would agree that the EIDS prevents stalling caused by VTA BOV. The only time I have had stalling with this unit connected was during a WOT run then sudden braking with the clutch down (ie flooring it then braking when someone cuts infront of you.)

Other than that, uslualy the RPM's will drop to 400-500 rpm and bounce back to normal idle. You can see the EIDS light appear when it is activated (at least of the AFR model.)

 

I've just started tuning the richness out of the car with my SAFC. I brought up the root cause of BOV stalling hesitation in an earlier thread. This is unavoidable with the stock sensor. The location of the MAF is before the BOV. What this means is that the sensor has metered the air going into the engine and the blow of valve is purging it afterwards. Your car will always run rich at this point because there is no other metering taking place.

This is where I still have a question. I am looking at going AEM stand alone or MAP-ECU and probably will install some sort of different air metering system. Where would I install this? At the IC pipe upper junction point? Any recommendations for the sensor?

 

I said that, no matter what the EIDS does, it still can't change the fact that the MAF isn't sensing the air that's supposed to go back into the intake, which is what causes the rich condition in-between shifts.

But people don't seem to understand that simple concept.

ALL THE EIDS DOES IS STABLIZE YOUR IDLE, hence the name.

 

uhm... map stands for manifold absolute pressure. so i'm thinkin' you'd install at least one sensor... in the intake mani... or throttle body or some place like that. yeah?

 

It doensn't really matter. On my racegas map, it's tuned for 12.5 afr. Between shifts it goes to 11.5. Not that big of a deal.
