COBB Tuning 3-Port Boost Control Solenoid
COBB Tuning is proud to announce the immediate availability of the COBB Tuning 3-Port Boost Control Solenoid (BCS) for turbocharged Subaru, Mazda and Mitsubishi applications. The COBB 3-Port Boost Solenoid is an excellent upgrade for modern turbocharged vehicles, enabling precise boost control in a tidy package that is easy to install and tune. Our BCS will eliminate boost fluctuations and boost creep inherent in OEM boost control systems, providing the necessary stable and repeatable boost control required for accurate tuning and consistent performance. The COBB BCS is equally capable of providing stable boost control at stock boost levels as well as extremely high boost levels associated with big-power builds, with an operating range of up to 120psi.
The COBB Tuning 3-Port BCS features 1/8″ low-profile barb fittings to keep the unit compact, and are nickel coated for corrosion resistance. Optional 1/4″ nickel plated fittings are also available separately. Viton spools and seals are used throughout for long life and lubricated with Dow Corning silicone grease. The manual override port is sealed with an O-ring, the wiring harness is sealed to the casing using a waterproof grommet and the solenoid wires are ultrasonically welded to the coil, making the device waterproof and safe to wash.
COBB Tuning has made the COBB 3-Port BCS installation as simple as possible. It mounts in the stock location and plugs directly into the stock wiring harness, making the physical install and electrical connection as straightforward possible. The BCS comes with a custom aluminum mounting bracket, stainless steel hardware, the necessary boost-line to complete all connections and zip-ties to route the boost-line neatly through the engine bay. The install instructions are easy to understand, with photographs and illustrations to guide you through the installation process, and include routing instructions for both internal and external wastegate configurations.
The COBB Tuning 3-Port BCS is the ulimate electronic boost control device for modern turbocharged applications, designed for outstanding boost control, engineered for consistent performance over an extended service life, and configured for easy installation. Get your boost under control and Access the Potential of your turbocharged Subaru, Mazda or Mitsubishi today!

[…] Not Ranked : +0 / -0 0 score Cobb EBCS Did I miss the thread on this? Thoughts? http://cobbtuning.mystagingwebsite.com/2012/05/…trol-solenoid/ […]
Are there any plans to suport this with Cobb OTS maps?
Hopefully in the future we will! I don’t have an exact timeline right now of when those maps might be available though.
Ian@COBB
Nice boost controller… How about on the fly tuning for the MS3 so it’s useful?
It’s something we’re looking into, we know it would be an awesome feature for the MAZDASPEED guys!
Ian@COBB
Will you guys be able to put a tune with this on the Cobb AP or will it still require a pro-tune?
thanks
The Evo X already has some beta OTS maps available. We hope to add other OTS maps in the future, but in the mean time you can use AccessTUNER Race or get a custom tune from a local tuner!
Ian
HI,
Does the 3-port not need a ‘pill’? I read thru the Installation Instructions and it doesn’t mention reusing it, so is one included w/the part or just not required w/a 3-port?
Thanks,
Td
The “pill” is not required when using the 3 port EBCS.
[…] Not Ranked : +0 / -0 0 score Also might try out this EBCS instead of the grimm… http://cobbtuning.mystagingwebsite.com/2012/05/…trol-solenoid/ […]
Do I need to tune my wrx after installation ?
Yes, the 3 Port BCS will require custom tuning after installation. Check out the section of our site to find a local tuner or an e-tuner.
Ian@COBB
Hi! Just wondering what kind of tuning I would need to do? Can’t I just pick an OTS map that’s already avaable for my 03 WRX?
The maps have specific modification requirements, but if you are within those, you shouldn’t have any issue using the OTS maps! Otherwise, you can still have a custom tune created and put onto the AccessPORT.
Ian
I have a 05 Legacy GT , will I need a tune after installation of the 3-Port Boost Control Solenoid ?
thanks Mike
Yes, the 3-port BCS does require custom tuning. Check out the dealers and e-tuners list on our website: http://www.cobbtuning.com/Dealer-Retail-Locator-s/70471.htm
Ian@COBB
Can i use this with a stock evo x with just an ots map? How much would i gain?
We do have beta maps available on our forums for Stage 1+EBCS maps. The power gains will be a bit higher than typical stage 1 maps with a smoother power curve.
Ian@COBB
Any plans to support the ebcs with Cobb OTS maps for the 05-09 legacy gt?
We don’t have plans right now to create OTS maps for that generation of car, but possibly in the future! A custom tune is your best bet right now.
Ian@COBB
I have the AP with the pill installed. Will I need to put the stock pill back on if I purchase the BCS?
I’m guessing this is on an Evo X? If so, you would want to remove the pill when using the 3 port EBCS.
Ian@COBB
Hey Cobb, Evo X SST owner here. I started with the acessport from you guys and now have a few cobb products, including Acesstuner Race, with nothing but astounding results. Could you provide a guide on how to use the tuning software to tune for your boost controller?
Hey Matt, I realize this an extremely old post however you can find our tuning guide at the following link: https://accessecu.com/support/docs/tuningguide/Mitsubishi/Table_Descriptions.pdf

I’ve got a ralliart 09 and was runnin on stage 2 but put on front mount intercooler,upper intercooler piping,lower intercooler piping,shortram intake band a Cobb 3port bcs show come thermes no stage 3 fort ralliart???
Completing the Ralliart staged maps is definitely on our list of tasks! In the meantime, send an email over to [email protected] and we may be able to provide something for you! – Marshall@COBB
Got a new bov too
I currently have a 2011 sti sedan
Mods: cobb sf intake w box, cobb catted downpipe. Everything else is stock. Including the catback.
im getting it protuned at cobb plano this weekend and I plan on keeping this set up. Just stage 2. Will it be worth purchasing this since I wont be doing any other mods?
Have you had the car tuned yet? We generally do not see much of a bump in power when using a 3-port solenoid on an otherwise Stage 2 setup. You can certainly see gains further down the line however the factory solenoid does just fine in these cases. – Marshall@COBB
Hey Cobb, i have a 2012 evo x gsr. Planning on getting this 3 port boost with your test pipe. Will the stage 3 map work? I have a megan catback and k&n drop in filter installed right now and running the stage 2 map on my cobb v3 accesport.
Thanks!
Erwin
Erwin,
The only potential issue is the intake system. Our Stage 3 maps were calibrated with a COBB SF intake system. You will likely need to do some custom tweaking to MAF scaling in order to use that map with a stock airbox/K&N panel filter.
Marshall@COBB
I have a 07 wrx running the stage 3 ots map, will I need to run the pill still because the map calls for it? Also will i need a retune after installing the boost solenoid if im still using the stage 3 map?
Thank you
Hey Danny, if you’re switching to a 3-Port EBCS you will no longer need the restrictor pill. A custom tune will definitely be required as the Wastegate Duty Cycle table will need to be changed quite a bit to use the new solenoid properly.
Marshall@COBB
Hey i have a stock evo x with a drop in cone filter can i install the ebc and use one of the maps on the access tuner??
Our Stage 3 OTS map is the only one that will have the proper calibrations for an EBCS. However, that map also requires an upgraded turboback exhaust and intake. If you only wanted to upgrade the EBCS you would need to have a custom map created for your car.
Marshall@COBB
2015 gsr here have your test pipe, down pipe,3 port ,k&n typoon plus borla cat mishimoto pro intercooler and lower pipes…..going through the pervious post having questions about the OTS map going to run stage 3 93 v403 with the changes I have made to the maf scaling and load calc tables per the intake..now stepping to stage two instructed me to remove boost pill…do I leave that out with the 3 port ? also im getting protune on april 25 I guess the question is can I run that map..for a month with no issues and about the pill?
Hey Ben, the restrictor will be removed when using our 3-port EBCS. You should be just fine with that setup leading up to your Protune. Feel free to email over some datalogs ([email protected]) if you’d like us to give them a quick once-over!
Marshall@COBB
just installed this along with the cobb bypass valve with the stage 2 + EBCS map on an 04 wrx. Other components currently on the vehicle include: process west top-mount intercooler, equal length headers, cobb up-pipe, cobb turbo back exhaust, and cobb SF intake box. i was hitting 17psi of boost before the install, now im hitting 9-10 (read from the accessport guages)… any idea what the issue might be? i’m planning on having this tuned shortly now that all of these parts are in, but i’d like to know why the boost pressure drop happened and if i can correct it before-hand?
Hey Justin, it sounds like you’re just hitting wastegate boost levels which may indicate an issue with the EBCS installation or valve itself. Can you double-check that the vacuum lines are all run to the appropriate ports on the valve? Are you getting a CEL for anything related to the boost control system? Also, be sure both the Reflash and Realtime maps are showing Stage2+EBCS.
Marshall@COBB
Quick Question, this was part of the package I bought for my Ralliart, now less than a month later I have upgraded to an Evo X. I am waiting for the Cobb SF and air box as well the UICP, I am installing my Turbo back Exhaust today, the AP has a stage 2 OTS map for the Exhaust, and you map notes doesn’t list the BCS until stage 3 which includes the SF air intake / Turbo inlet. Can I install the 3port BCS on the stag 2 map or should I wait until the intake and install then?
Thanks in advance
Hi Justin,
You’ll need the intake and running the Stage 3 map in order to use the BCS on an OTS map. If not, custom tuning would be required.
