Hey guys,

Sorry to create a thread about this, Ive tried searching but I cant find what I am looking for :S..

Just wanted to know how the stock boost gauge works? what does it read in? as I am looking to put in my Turbotech boost controller in, I want to set it to 10psi.

Cheers

It reads in mmHG (x100)

1 PSI = 51.7 mmHg

1 bar = 750 mmHg

So..... '7' on the stock guage = 700 mmHG which = 0.93 Bar or 13.5 PSI

10 psi would be about a 5 on the stock gauge. Its pretty hard to pinpoint & guessing is not the sort of thing so you want to do with boost pressure so you need to get another boost gauge. :P

before i ran more then stock boost with an aftermarket boost controller, i installed an aftermarket boost gauge which reads in PSI, cant go wrong mate

if you dont want to do that, the above post is correct

Get an aftermarket one, or do it on a dyno, simple as that.

The stock gauges are generally too inaccurate to be reliable.

Do yourself a favour, and dont trust it or you could find you blow the turbo.

    • 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.
