Aem Ems questions

[chad_KAT]

How do you convert to MAP sensing? i would like too know becuase i would like to vent my BOV. Now if i was to still useing the MAF, is there a way i can tell the computer that im venting or do i need to still recirc it to get proper performance.

Converting to MAP with the EMS is extrememly simple. Basically just remove your MAF and set up all your piping as normal-- the MAP sensor just gets a vaccum source from the manifold somewhere, and then gets pinned into the EMS (the MAP also gets a +5v reference source and a sensor ground). Setting up the MAP in the EMS is as simple as picking your MAP sensor from a list.

Open venting the BOV with a MAF is a different story, which I am not entirely familiar with-- someone else should be able to help you out here, although I do beleive it is either difficult or impossible to do without having issues. Why would you use a MAF with the EMS anyways? That would be such a waste-- the MAP sensor is like 30 bucks, free if you order it from certain vendors.

Going with AEM so you can run your BOV open is like using a sledgehammer to install finishing nails....lol.

lol good comparison..

cool sig BTW!!

ok, fiz where did you get your aem ems with the map sensor....or where could i get the map sensor at?

u can run an open bov with maf. i do it currently with no issues. i am using the safc one (silver with blue display which has no knock sensor thingy) with a non blow thru setup and a greddy type s. my idle holds perfect if i drop into neutral. Now the only issue i really have is if i am boosting and shift right into neutral; then again, doing that is just asking for a stall lol. I did it tho to find out how good the decel function really is so unless u plan on doing sumthing like that day in day out, u can run an open bov with the maf.........

they have the s14 obd2 out yet?

The E-manage from greddy has an anit-stall feature that Is what I plan on using once I get a bov on the greddy kit, plus it can do fuel and timeing for about $550 or so for the whole package. You might want to look into that.

Yes, its been released for some time now. I just ordered several for customers and currently, they are in stock.

The anti stall function on the greddy Emanage clamps the MAF voltage to keep the car from stalling. This also messes with cold start. With the MAF voltage clamped you wont have the fueling to get the car started cold.

im 90% towards the EMS and 10% to the emanage the only difference is price, but for very good tunning and lack of headaces the ems wins.

[chandler]

but is the obd 2 s14 one out yet

yep, been running it since march.

how so? the emanage clamps MAF value only withing a certain rpm window which is user adjustable.

What I though also correct me If I'm/we're wrong tho plz, and In no way am I saying the e-manage holds a candel to the EMS but once cost is a factor. I just don't got the funds

[chandler]

what about emmisions and obd2, does it still show rediness codes and such to pass inspection testing, thats my main concern

nope, gets rid of all that stuff.

[chandler]

what, thats messed up, I was going to get it but if I cant pass obd2 because of reddiness codes I might as well go with emanage or something

[DRIFTEADOR]

usually, if you can afford a standalone, you can spare an extra $40/yr towards inspection

[chandler]

well, obd2 you have to have the reddiness codes and such in your computer, and thats why I didnt want an sr or an RB, they dont have those in their computers, but the 96 and up ka's do, I want to be able to pass inspection with out greasing a palm, thats just my feelings on it
