Hi Guys,

Im due for a dyno tune very shortly.

The vehicle i have still has the OEM boost solenoid.

(the previous owner was an idiot, disconnected 1 of the 2 hoses and didn't want to tune it because it costed too much. pretty much sold the car because he was due for a tune and the boost he was running required supporting mods that he couldn't be bothered with.


The hose that was disconnected is one that comes out of the turbo / Actuator, to the solenoid.

Apparently this was to keep the boost down, the actuator is 22psi actuator but it is somehow its running on 20psi.

Ive now purchased an electronic 3 port boost controller to be set up properly. (i must say, you americans design and manufacture great products for the world. The parts for japanese cars are usually even better than the branded ones out of japan)

Anyhow, the tuners recommend that i install the boost controller myself, otherwise they would charge $150 AUD (approx $140 USD) to install it.

Since its only: 1 bolt, couple of hoses to pull out and push back in.

If i was to drive it to the tuner? would anything happen?

Also on another note, I'm curious to know…
would altering boost affect or change the sound of the exhaust tone?

All replies are welcome.

 

I don't think it'll be a big deal to drive AS LONG AS YOU KEEP OUT OF BOOST!

But since you said its an easy install "1 bolt, couple of hoses to pull out and push back in", why don't you just drive there with stock and then change it on the parking lot to be on the safe side?

 

This part is easy to install. I could literally do this in 30 mins the first time I did it. Just leave the stock bcs in the car. Then go to the tuner and install the new part.

Here is a well written tutorial that can take you through most of the process:

On an un-tuned evo the Electronic Three Port Boost Control Solenoid can cause the Evo to overboost and can cause many other issues. I would recommend not driving the Evo to the tuner because of this.

 

you'll be okay, just don't boost the car.

 

I appreciate your responses guys.

Yes i guess that would be a good idea too. Rock up 30 mins earlier and install it there.

Deylag, the one i have is the Grimmspeed. I believe it should be a lot easier than the one you pointed out.. since it probably won't require the welding of the resistor?

Im pretty keen on this dyno tune …


Im guessing all of you have boost controllers installed already, did you notice any change in exhaust tone?

 

Yea there is no need to put in a resistor for the Grimmspeed Electronic Boost Control Solenoid.

I did not notice a change in the exhaust tone.
