Poor man's 3 Port EBCS

[mazdafreak]

I picked one of these up months ago! Havent installed since car is stored for winter and waiting for built motor etc....Glad to see someone else picked it up too.


Thanks for the links on the harness tho!

Don't think I posted a photo,here is one.

You bet- Glad the connector is finally available!!


I just pulled the trigger on the cobb 1/4 in kit. It's easy enough to just order the spiffy pnumadyne fittings, but this is just as easy, has the spiffy fittings, and I needed some vac line too

Im using these clamps.. got the idea from a rather smart guy These are MUCH easier to take on/off, rather than cutting the zipties off everytime you need to pull the TIH.



Also using 4mm Silicone tubing and 1/4th in Barbs. My #2 fitting, that goes to the wastegate need to be replaced with a 90* fitting since its almost too much of a bend and I don't want it to restrict ant air..


And this was my starting values for the BEC..

0.10 0.09 0.08 0.07 0.06 0.00 -0.06 -0.11 -0.22 -0.44 -1.10

Will need some more adjustments but its been pretty crappy out so getting clean logs is a challenge.. Thanks for the help

^ Those clamps come included with our kits as well. 6 to be exact for the EBCV.

You are the smart guy I referenced in the post above

While I do enjoy putting together my own stuff and DIY's... But if I could do it again I would prolly go w/ Lex's EBCV.. Easier overall

Ya, see this is what I would think. But what is nipple size on BNR WG? If 1/4" then Ill just get those...

1/8" fpt iirc, with a 5/32" barbed fitting in it.

Just ordered Mac's 4-port ebcs......I currently run the Mac 3-port just as OP. but switching to 4-port since im running ewg and rob wants me too lol

So I want 5/32 then. I will confirm with Bryan tmrw or wait until mine shows up before i order.

Good read. Subbing for future use. I'll probably end up going with stratified's piece but this is good to know.

What size did you use for 1/4 barb? Where is the best place to buy?

per Bryan BNR comes with 1/8 barb for stock and 1/4 barb. One needs to be plugged.

Yes. The new BNR actuator comes with 2 fittings. I would use 4mm inner diameter silicone tubing available here: ( @aviator79; )

ALSO: you will need a high temp silicone vacuum cap for the other nipple on the wga unless you want to check it weekly.

The standard rubber ones have cracked on many wga's causing overboost situations.

THe nippes are not fittings? They are moded into WG cap? I assumed I could buy a plug. That sucks IMO...

Yes. They are flared nipples that are a part of the wastegate actuator.

On the new BNR if running in 3 port, cap the top port. An easy way to cap a port is a short piece of hose with a bolt tightened into the other end of the hose.

Iirc I capped the bottom port... what's the difference?

tapping....

[kritz]

One is on the top and one is on the bottom.

Top port has a restriction/is smaller.

So if you are moving air in and out there will be a bit more delay for the top port and the barb is overall smaller making hose fitting a bit tougher.

That makes sense... has felt a quick pause/delay before pressure/spool builds

instead of a pigtail you can get just a plug and put it all together by yourself :
Tyco/AMP Econoseal J Series Mk II Motorsport Connectors - Corsa Technic
this is 174354-2 from Econoseal J Series Mk II
I'm 99% sure this will fit. will confirm in a week or two when I have mine installed.

edit: the link above is an example. I didn't buy from this store, there is a lot of suppliers locally.

@TiGraySpeed6;
OK. the plug / connector works. Anyone who wants to save 5 more bucks on the project - this is the way to go

[BAT-man]

Bit of a resurrect -
Installed the self made EBC in 3 port mode (same one CS/GS/COBB/JBR make), soldered up to a plug-in connector, so very PNP and straight forward, just like the GS/CS instructions say.
Problem: Get overboost even with WGDCs at 0% (the overall map is 30% of the old stock EBC map). I logged WGDC of 0 starting @ 2500 rpm, with boost going to from 15psi to 23psi at 270rpm (targeting 17) before fuel cut kicked in. So the LEC/BEC tables did their job, they made WGDC 0 but boost kept rising.
Do I really need to remove the stock turbo fitting restrictor? The instructions for COBB or GS don't say to remove it... There are a few folks who say it's not necessary to remove the pill: GrimmSpeed 3 Port Boost Control Solenoid ?
The turbo being on the car, I'd rather cap off the turbo nipple and tee into the BPV vacuum source.

As a side note, does anyone know if these little paths in the bottom part of the EBC do anything?

I was worried about the seal to the top part so I put a very very minimal amount of silicone there to provide a light seal so that that there is no air coming through the plunger opening affecting the ports... but now I wonder if those paths are there for a reason. It really does look like there is a gasket supposed to be there though... kind of like the OEM BOV flange gasket.

Finished product:

[BAT-man]

Partial solution - I did have the hoses mixed up somehow. After hooking them up, I am able to maintain boost of 17.5 as targeted, BUT:

Only until 4,300 RPM. This is where WGDC drops to 0 again, while boost stays at 18psi tapering off to 16.5 at redline.

This feels like the restrictor pill is perhaps keeping enough pressure out of the WG diaphragm to avoid opening it when necessary to keep the boost down. I just don't have another explanation right now.

Anyone chime in to confirm?


UPDATE: Switched boost source to tee off the BPV valve, as per CS instructions. Now I am making boost properly, but have trouble getting it over 19psi between 3.5K-5.5K, my WGDC commanded values are into the low 50s now, which I thought wouldn't be the case with a 3-port EBC. Regardless, it's working fine now, the WGDC curve just looks a big different than the OEM one.

@BAT-man;
Resurrect #2 I am having same issue over boosting on initial spool up but the kicker is that everything was working fine a week ago I haven't touched anything.I am using TIH as boost source just like you. I get 12-13 psi a spring pressure, I replace all the lines with no luck and I order a new EBC to see if that fix the problem.
