hi guys, ive got an r34 using the standard 3 gauge holes, ive got a trust electronic boost and oil temp, should i either

1 get another water temp for the 3rd one or

2 get an air/fuel one and have another water temp in the glovebox, just to see the temp at the back of the engine

I'd get an oil pressure gauge.......... :mellow:

The best four gauges are Boost, water and oil temp and oil pressure.

Most skylines have factory oil pressure, even though there inaccurate it still gives an indication.

I'd personally get an Oil temperature gauge my self.

ok, if you already have boost, and oil temp then you need oil pressure.

the common air fuel guages using the stock sensor are about as useful as a screen door on a spaceship so forget that idea.

water temp is not so important either and if you have a Power FC it will display it anyway.

the most crucial gauges in order of importance are:

oil pressure

boost

oil temp

fuel pressure

water temp

ext temp

air fuel is not on this list as it doesn't even really rate as a gauge. more of a flashy thing to keep passengers occupied.

amen.....

i'm sooo selling mine at some stage in favour of using the space for fuel pressure

I disagree on the order of importance slightly. I'd put water temp higher up as it's easier to tell whats happening at a glance of an analogue meter rather than trying to read the pfc screen when the sun is on it and the cars bouncing around a track.

Boost goes lower on the list as it's just another gauge that bounces around. boost controller with peak protection and peak recall will do it. You don't need to see what boost it's making all the time. I look at mine maybe once in a session on the track just to make sure the peak is right, then don't look at it again.

Oil and water temp as well as oil pressure get checked once a lap. I'm giving serious consideration to installing a bigger oil pressure gauge with built in low pressure light next to my boost gauge on the a pillar and ditching the egt thats there atm.

yeh air fuel isnt really that important if the comp is tuned properly with correction maps set up huh, i mean cause if the engine leans out you'll probably know about it before you look at the gauge, now i just gotta find a water temp gauge, the boost and oil temp trust gauges ive got are discontinued now

actually that's not really true AFR is vitally important. but any gauge that uses the stock sensor can only tell your AFR between about 14:1 and 13:1 so it's absolutely useless for anything other than steady state crusing. if you are thinking about a wideband sensor and proper AFR display then sure go for it, but I'm pretty sure that's not what we are talking about here.

BHDAVE has some good points.

yes I rarely look at boost gauge now, but in the initial set-up and testing of the car it's very important.

oil pressure is most important by far. I have mine set to record for my first two laps at any track and I have a warning buzzer, and a big shift light type warning light for it.

water temp, I can see your point, but I found PFC is ok for me even on track, and if things start to go bad the stock idiot gauge will start to ramp up towards H around 100 degrees or so.

i was planning on just using the standard R34 oil pressure gauge, they should be pretty reliable shouldnt they, i know the r32 ones stuff up but the r34 is newer so should be ok

the standard oil pressure gauge is rubbish. if you are spending money on gauges then oil pressure should be one of those gauges. it's not so much that they are unreliable, but they are VERY slow to re-act and often a fair whack innacurate too.

yep - standard the oil pressure gauge did nothing for me at sandown, when my car was leaking oil like a mofo......I was told to get an oil pressure gauge for hte next track day....the tow truck lady asked if i was looking at the oil pressure gauge in the car, i said yes, but it was saying that everything was fine (but obviously it wasnt)......so yeah id probably go the oil pressure gauge.

What oil pressure gauge you running baron?

The man runs Defi's

One question - how much does it cost to have a wideband gauge installed? cos i want one installed in my 3325t

Its not really about "cost of install" there are some complexities.

There’s a lot of debate about the best units in the pro tuning world it seems. Iv heard first hand many deficiencies with less developed units like the Tech Edge, which don't cope with altitude change well, and are a little slow in response. If your really keen, at a minimum starting looking http://www.innovatemotorsports.com/products.php Look around though, you can pick up some good second hand deals. A mate picked up a LM1 for under $800. Tested response with $5000 unit; sensor still seemed fine.

You mention permanent install? Keep in mind the sensor needs a constant power supply to stop the pump cell from coking up.

Others use the setups from Haltech, Autronic etc, which I believe are rebadged LM-1’s and another who’s name evades me atm.

...I was told to get an oil pressure gauge for hte next track day...

Gauge isn't going to help you with a oil leak :)

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
