Auto Meter Gauges Are They Correct?

Recommended Posts

Hey all, had a check and cant find one,

Bought me an Auto Meter boost gauge ultra light mechanical series, fitted it to the vacuum line on the throtle body and getting an reading of 7 psi low boost and 14 psi high boost, yet my stock reads 6 psi low and 7+ on high would this be true?, as i am running a supposed stock R33 fresh import from Japan.

Parts fitted are,

Just Jap 3" turbo back dump,

Apexi pod,

Looks like an Nismo ECU havn't pulled it out yet,

Cant find any signs of boost controller or tampered waste gate, could it be from the ECU or maybe an High flow stock turbo any signs to know if it is?.

Yeh ive got a r32 gtr and just finished putting in 3 auto meter guages in last night! (boost, oil temp, oil pressure)

They all look spot on to me. And yeh, original guage was in mmhg which meant nothing (to me at least) . Milligrams of mercury or something

On a side note, do your auto meter guages make this freakin annoying beeeeeeeep sound when you turn on the ignition ? Part of some 'test' feature im guessing when you first turn them on. its so shit

Also... does anyone know if the stock boost sensor is required for the ECU to operate correctly ? Now that i have aftermarket boost sensor/guage i dont see the need to keep the stock one unless the ECU needs it to run the engine efficiently

nope no noises here havnt wired up the light yet but it only runs off the parkers so i cant see that as a problem, sounds like yours have the warning buzz and light for if it gets too hot.

    • Here is my 2013 Nissan Skyline 370GT Type-S has a factory Nismo exhaust and Enkei rims. Shes completely unmodified. Brought her from Cult & Classic and drove down from NSW to Tassie November last year. 
    • Yet another thread bump because I want to talk about this: The general gist that this guy found for a MK7 Golf GTI is that by adding a venturi from a 2022 Tiguan he managed to pull crankcase vacuum far more reliably under boost which effectively stopped oil consumption on his engine in track conditions. An earlier video details how that venturi works: Basically one port is atmospheric vent, one port goes to a boost source, and the last port goes to the crankcase vent. There's a lot of discussion on here about scavenge pumps and all that fun stuff, why not try to replicate that by pulling some energy off the compressor? There is one catch though and that is that the PCV diaphragm on these cars appears to completely block off airflow from the intake when there is enough crankcase vacuum. This contrasts with the RBs where there is basically nothing stopping vacuum from the intake from sucking a big gulp of oil if it gets into the crankcase vent.
    • Hi All, Brought a 4 Door 2013 Skyline 370GT Type-S in November last year. Absolutely loving the car, noticed a few audio issues speakers cutting in and out and the 12V circuit seems to be completely dead (after checking and swapping the fuses) but just wanted to say Hi     
    • Could you please express this thought again with some clarity added?
    • So, whilst the Bogan Cruise Ship is GTG, and I had organised some time today to go on the SAU NSW cruise, my best laid plans where kicked in the balls, well, kicked in my right knee to be exact Now, after a bit of arthroscopic "honing" and tibial band lengthening "modifications" , I'm sitting on a couch in a prescription induced drug haze, watching 5hit on the Youtubes and falling in and out of consciousness......good times
