g'day fellaws.

i have installed a stage 3 boost controller. but i cant set the psi's.

at all 3 stages the psi are set to min. but on ma boost gauge it shows 14.5psi at the 3 stages.

now i noe that 14.5psi is going to kill ma tubo and thats y i need ur help ASAP.

have a look at the pics. tell me if i left a hose out or didnt block a hose... or wrong way around.

wateva helps.

now its electronic obviously. so i got the wiring done by a mechanic.

im not sure if the stock solonoid should stay wired, and jst bypass the hoses, or disconnect completly?

thanks guys any help will be greatly appreciated.

:(

Plumb your new ebc directly to the actuator and a point just after the compressor outlet or where ever the r33 gets it's boost signal from and bypass the factory solenoid completely. You can leave the solenoid hooked up but just make sure you block off any hoses that will cause a boost leak.

so i can completely remove the stock solonoid! great. there are no hoses going to this solonoid anymore! nothing to block

where is the actuator , i thought wastegate is the safer and more logical way to connect the ebc to!?!

jst cant figure y i cant set ma boost less dan 14.5psi...

:bs!:

Ah, thought you had the two in tandem as the new ebc is tee'd into something.

The actuator controls the wastegate so we're probably talking about the same thing.

So now i'm stumped because if you remove the facory boost controller the boost should drop as the wastegate is pretty soft so with the new ebc hooked up and switched off it should read about 6-8psi depending on other mods

mods = 3inch madrel bent turbo back [nismo], apexi intake & apexi bov.

its jst hooked up to the elec solonoid, stock one no longer is hosed or wired to anything! i tried wiring the stock solonoid but no diference.

the 2 blue hoses are the only thing conected to the new solonoid and the wiring to the controls in the cabin.... i have check the instructions and the hoses are going into the right coms, maybe this will giv u a beter idea.....

thanks bhdave...

The question is, is it a plumbing problem or an electronic set up problem.

The way I do it;

Eliminate the plumbing possibility first. Unplug the wiring from boost control solenoid, but leave the vacuum hoses. You should have standard boost, the only thing holding the wastegate closed is the spring rate in the wastegate actuator.

If you have normal (low boost) then it is an electronic set up problem. Reconnect the wiring and read the set up instructions. Set it up EXACTLY as per the instructions.

Hope that helps:cheers:

if it was electrical , wat would it be....

as i am sure that the ign, earth, blue ext, purple ext are properly connected, the graydoes not need to be connected as im runnig closed loop.

my only dout is that the mechanic connected the orange [boost sensor wire] in the wrong spot!?

any help'?

Don't worry about it, it's blocking the stock BOV return line as they have fitted an atmo venting BOV.

All you need is to tee into a boost signal point (basically any point between the turbo compressor outlet and the plenum will do, your diagram has it tapped into the fuel reg signal line by the look of it which should work okish) and a connection to the actuator. No tees in the connection between the solenoid and the actuator, just a single bit of pipe.

If it's connected this way and you switch off the ebc you should have slightly less than the cars stock boost and so you have eliminated any problem with the plumbing as SK has stated.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
