GrimmSpeed Boost Control Solenoid Install

GrimmSpeed introduces the most complete and easy to use 3-Port Electronic Boost Solenoid available on the market. Our aftermarket boost controller allows you to raise the OEM boost levels in a quick and efficient manner. If you try to raise the boost on the weak OEM boost solenoid it will start to become unpredictable and unable to maintain proper and safe boost levels. Using our solenoid you are able to spool your turbo quicker and maintain a rock solid boost level. We have made our solenoid to withstand 120psi, way more than any Subaru will see.

i dont understand, if u install this you get more boost right? so why do people install bigger turbos when you can do this for more boost?

[GrimmSpeed]

@sergsrt8 Great question! Let's break it down a bit here, more boost in most cases will mean more horsepower if properly tuned, however a smaller turbo will not be able to flow as much air and it comes down to the velocity of air that the turbo is capable of pushing, not just the PSI. Also teh OEM turbo has definite limiting factors strictly related to PSI where a larger turbo is capable of producing more PSI at a higher velocity. - Will

What does it mean by ,"it needs to be tuned"

[GrimmSpeed]

@ChicanoRockero Installing this alone will cause your car to overboost which could be potentially catastrophic. You need to bring your car to a tuner/dyno to get the ECU reflashed with a custom tune that allows to BCS to operate in conjunction with your engine correctly.

Controlling boost only allows you to max out your current turbo, it has its limits too! e.g. sr20det engine (found in nissan s13/14/15/pulsar gti-r) has a turbo capable of around 280hp, so almost +50% increase in power with sufficent supporting mods, such as fmic, exhaust, injector, possibly fuel pump, and of course a tune-up to keep it from melting. But as the sr20det can take 400hp with the same mods, that's why ppl want to bolt on bigger turbos!

will this work with a cobb accessport? and do they have pre made tunes for a boost controller?

[warriorlax048]

will this fix boost cut on my 05 wrx?

[MrDosstheBoss]

So can you install it without taking it to a tuner/dyno? can you just change the psi setting on the controller? what about manual ones?

[ethosflux]

@alfa69er nope, no reusing the pill. That's what makes this system awesome, you don't have to muck with pill sizes.

[ethosflux]

@GrimmSpeed Depends on the ECU version. If you reset your ECU, your initial wastegate levels should be low enough that boost error will only climb them back up to where they need to be to hit the right target boost numbers. But if you were to just throw this on your car and drive it, yeah it could be ugly, since the wastegate duty cycles will have climbed to hit the target boost numbers for your old BCS.

[ethosflux]

some extra advice might be to have people reuse the clamps, or hoseclamp the vac lines onto their nipples. They will blow off at 24psi plus boost levels... had it happen to me :)

@fbjr2003 Hey man, NOPE you will actually have to go directly to a tuner, the Cobb AP can only be protuned to work with any aftermarket BCS, there is currently no OTS map for it!
