KA24DET stalling issues

[greenb0y]

Hey guys,
new here to zilvia.
I have a question and any info/help is appreciated.
I recently got my first 240, an s13 coupe with a turboed '93 ka24de.
For some reason, when slowing down/cruising my engine starts to bog and die.
It doesnt do it if i tap the gas and give it gas. I can not put the car in neutral for more than 2 seconds or it will die.
It also gurgles and backfires when heading into lower rpms in either 2nd or 3rd gear.
Is this a problem with my afc?
I am running an APEXI Neo
I found a link that talks about throttle % with 370cc injectors so i will try that when i get home today and the engine is cool enough.
Let me know if you guys know or think you know what the problem is, thanks!

Bov open to atmosphere and running rich on decel causing you to stall. Run blow through maf.

so if i were to recirculate the BOV would that eliminate the problem?
to me it seems like an easier solution than setting up and tuning a blow through

It may fix part of the problem, but it sounds like you're running too rich. What's your afr look like?

Recirculating blow off valve will also solve this issue. But TRUST ME when I say this, going blow through is easier to do and ALOT better. If you blow a coupler on blow through, you can still drive the car with no issues, but you can't do that with pull through. I just recently switched to blow through after trying the recirculated blow off valve route, and I love blow through alot better. Take my word for it bro, blow-through is great.

thank you so much for the information!
so how exactly does a blow through work? do i literally just buy a z32 maf and that will solve the problem? or is there something more i have to do, i am not familiar with the problem

and how do i go about putting the maf in the piping for the intercooler? (i think thats where it suppose to go). its hard to find information about how to set this up haha i can find info on how to tune it and pro and cons of it!

you can either get a z32 or a cobra maf either will work fine, just rewire and youll be set, also make sure your plugs arent screwed.

so its okay to have it that close to the fmic 90 degree bend? do you have any trouble with that or no?

[shift_down]

No trouble at all. Just make sure there is atleast 6 inches of straight pipe before and after the maf
