Anyone got one of these? Ive got the same (except in psi) and for the life of me i cant work out how to stop the start up noise (never really bothered me until now. Im sick of the 5 second screaming noise whenever i turn the car on) the instructions say to hold down the peak button when starting the car.. It doesnt work - ive tried all other combinations i.e holding it down when car is completely off then turning it on... having it on accessories then holding it down and starting the car.. nothing seems to work!

Also being that my skyline is fairly stock im hearing a slight scraping noise near the turbo. I was thinking the turbo is on its way out but it still makes approx 10psi by 4000rpm-5000rpm. The turbo was on its way out surely it shouldnt still be making decent boost? (I've tested it by turning down the boost - then upping the boost to get R&R)

Turbo noise could be the bolts holding turbo onto manifold. Most RB25DETs seem to have this issue. Just pull back the metal locking tabs, and be shocked at the fact the nuts will be finger tight.

Make sure the gauge is wired correctly. If the constant and switched 12v is hooked up wrong you cannot turn off the beep.

Once thats sorted,

Press the button on the gauge and Hold

Switch the ign on

Let the gauge finish the opening ceremony

Then let go

f**k i have got a water temp and a oil pressure of the same brand and it shits me to tears. I feel like smashing them after listing to them over and over. I have done what KWS explined but mine will make the noise once i turn it off and back on again. So maybe mine is wired in wrong!

      Slight brake pedal stutter after new pads

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
