[Help] Removing Electronic Boost Controller [Help]

[morbsy]

Hey all,

I need to remove my EBC to get through the vehicle inspection station.

I'm doing it on an R33 GTS-T, and i just need to know what vacuum lines to disconnect and what do i replace them with!

Any help is appreciated

Thanks

Need to remove the line going to your ebc and fit the standard boost solenoid in there. You will see your ebc tapped in between some vacuum and your wastegate. Get rid of that and put your boost solenoid in place.

Step 1. Pop bonnet

Step 2. Find boost controller solenoid

Step 3. Locate line going from actuator into boost controller solenoid and line going from boost controller solenoid into intercooler piping.

Step 4. Disconnect lines and connect line directly from actuator into intercooler piping (essentially by passing the solenoid).

Step 5. Remove boost controller solenoid - will have wiring going from it into the cabin of the car.

Step 6. Remove all evidence of boost controller inside cabin.

Won't this be relying on the wastegate spring to control boost? If so he should take it easy while driving it, those old springs and wastegates get tired.

Well a boost controller can only run more boost than the wastegate/actuator allows. So disconnecting it will result in only running less boost.

As above. Easy and best way to do it

That is true but judging by my current car, I wouldn't rely too heavily on it. My spring seems a little sticky and my wastegate is leaking. Switching my boost controller off(0%) I had boost hit about 12psi.

Best advice is remove what you need to, have it tested then put it back on. Drive the car easily though.

Well that doesn't really make sense. A boost controller stops air from going to the actuator by bleeding it to atmosphere. This in turn allows the wastegate to be shut for longer and therefore make more boost.

With the boost controller set to doing nothing (off/0%) it will not bleed any air, and therefore it basically acts as though it wasn't even there, ie. running actuator spring pressure.

Hence why you can't run less boost pressure than what the actuator spring can take, there is no way for it to do it.

What boost controller is that?

The only thing I can think of is that with the boost controller still plugged in but set to zero is providing a slight restriction between actuator and boost source. Have you tried bypassing the boost solenoid altogether and taken it for a drive?

Have no reason to take it out. I was just fiddling with settings trying to diagnose my WG as its old and I suspect its leaking. So if its leaking, It might not see a proper pressure signal and work accordingly.
