[@tommygodwin6472]

nice one mate...i couldn't understand what the " +12v battery" connection was for on the wring diagram when I bought my gauge, so I rang SAAS ... I was told they have one gauge technician and he only works Monday and Tuesdays can you believe that! i spoke to two other blokes at SAAS and none of them could tell me what that constant 12V feed was for. Then I find this vid of yours and boom now i know its to cover the memory settings ...nice one

[@willbutler5966]

If anyones got any issues getting through the firewall grommet, I find a metal coathanger unfolded does it perfectly, little bit of wd40 or some dishwashing liquid helps bring the cable through easier

[@bigfella6629]

That boost line pick up in the intercooler pipe is in wrong place hence why it over boosts on occasion also you should have a dedicated boost line just for the gauge, meaning you shouldn't share that boost line with another line. I get my boost from the intercooler where the map sensor is with an adapter..

Mine does this also i run mine from adapter randomly started about 3 mths after installation

[@bistratoaie2901]

Good work mate! I installed the same dual boost gauge a few months back and it performs great, your boost is a little worrying tho, I'd be looking at installing a tillix and needle valve for a nice linear boost control, also my EGTs are sitting alot lower than yours I'm yet to see 400°c even at 100km/h on the highway I'm sitting at roughly 350°c, I have recently had a ECU remap tho.

[@Alex.G]

It does have a dawes and needle valve on it which I believe does the same as tillex, so maybe it just needs some tuning? Problem is I have no idea how the shit works 😟 interesting about the EGTs, standard intercooler on yours? Mine is standard. It gets up around 480 degrees at 100-110km/h

[@bistratoaie2901]

@@Alex.G Ah I see, mine definitely holds boost better and it is a more linear curve, doesn't bounce around as much. It is a bit of trial and error, usually try and set boost with the needle valve fully closed (fastest spoolup) then adjust the dawes at a reasonable boost level (15psi for stock?). Then its just opening the needle valve with the engine idling till the actuator arm just drops from the grub screw and work from there, if it's too aggressive a spool rate or you get limp mode, try opening the needle valve for less of a spool rate, about 1/4 turn at a time, it's quite frustrating and takes some finesse. Yes I have a standard intercooler that was rewelded previously, EGR blocked, 3" straight through exhaust, complete rebuild done 55,000kms ago.

[@dingodazz3724]

@@bistratoaie2901 The larger exhaust definitely helps with EGT's and the higher the boost the lower the temps also, I run 20psi and temps usually sit around 250 - 300°c at 100km/h with 33" tyres. I have found that as the Dawes vales wear a bit they seem to get stuck and cause a slight delay in controlling the boost, the newer ones have a different material ball inside that seems to last better.

[@michaelsimpson9779]

Sounds like its running a bit lean, the richer the diesel AFR, the hotter it'll run. Mine was regularly exceedung 500 deg C, but not developing more than about 7PSI which would bleed off to 5 as the revs went up, I disconnected my wastegate actuator as I thought it was faulty, and now I'm seeing around 10PSI plus as I get up into 3000 plus RPM and the EGTs with the resultant leaner mixture (more air), peak at around 430 now at WOT uphill. On an old 80 series with a 1HZ.

[@Fi1del]

hi great video ! i have a D4bF which is basically a updated hyundai version of the 4D56t (pajero engine 2.5Ltdi) - it has a mechanical injection pump , my question is, i want to install a boost gauge , should i tap into the injection pump boost line or into the wastegate boost line ,,,, interested on your thoughts

[@ashleykeep8701]

I've got those gauges in my GU Patrol. I've found them really good and have had no issues with them. The EGT will go crazy if the probe gets wet but comes good once the probe dries off. They are however very bright at night even when dimmed, so I've put a piece of window tint on them.

[@TheJanope13]

How long have you had them? I had 3 sets within warranty period (replaced twice) and the third died shortly after warranty period was up. Worst thing i've ever spent money on. I did like how they lloked though and i agree the 7 segment part is far too bright.

Great video, like all of yours, thanks. One question, would you please be able to tell me which clip-on mirror you are using over your reverse mirror? thank you.

[@Kinimal]

@3:35 You mention the best place for the boost sender and I agree that's an accurate reading of what is going into the motor but curious is it safer to have it Tee'd in near the turbo like everyone usually does to measure what the turbo is making? Even though there may be some wastage after wouldn't it be more important to make sure you're not pushing the turbo too hard or making more than it's rated for.. eg. Turbo rated for 19psi and you're seeing 19psi on the guage at the intake but the turbo could be making more and you don't see it because you're reading it only entering the engine? Love the vid btw just curious to learn before I do this myself

[@Alex.G]

Very true points there, I guess it depends on your individual case. For my ZD30 the turbo is known to be happy with high boost but there's a factory ECU fuel cut if the boost hits something like 16 or 18 psi, so for me it's important to see that I'm accurately hitting no more than 15psi

Hopeful that you read this, but i have a few questions Why not use piggy back fuses for the wires And does it matter if all the power wires are to accessories or does it need to be all separate, i dont mind having the light on all the time

[@Alex.G]

You could definitely use piggy back fuses, I just wasn't into the habit of using them when I made this. If you put everything to accessories there is a chance you lose memory (gauges won't keep the colour you set them to, alarms won't keep their set parameters) but I'm not 100% on that cos it's been a few years since I did it

[@xterrorx8376]

@Alex.G thanks for the reply mate, I think my new gauge doesn't work so iv pulled everything apart for nothing haha just one of those days

[@TheLukesolly]

Your boost seems to be all over the place, id recommend a tillix valve as that will help stabilise the boost and keep it say at a constant 15psi under load.

[@darcykeddell4930]

Looking at them for mine, got much experience with them? Do they make it so the boost cannot go above a certain value or not

[@TheLukesolly]

@@darcykeddell4930 a tillix kit will limit the max boost, takes a bit of time to adjust(with the assistance of a boost gauge). And you also get a needle Valve so you can control the spool up of the turbo aswel definitely improves drivability

Looks like your intercooler might be leaking at the crimps.. the black oily marking on the core near the tank at the intercooler inlet. Common issue with the genuine intercoolers. Thanks for another great video, Alex.

[@Alex.G]

Thanks Evan. I have often wondered if the intercooler is shagged. Not too sure how to check it.

[@dingodazz3724]

@@Alex.G Yes, agreed it is leaking (all the factory ones do eventually), the black mark is from the oil that gets ingested back into the motor from the rocker cover via the intake pipe (a catch can helps minimise this). You can mix up some liquid detergent & water and spray or lightly pour over the joins (same as you do when looking for a gas leak) and with a little bit of throttle with the transmission in drive (while foot is firmly on the brake) to bring up the boost a bit - if there are bubbles there is a leak. It is easier to do this with two people. I changed mine over to a fully welded one and as such have no more issues.

[@jamieh4x4]

Looks too hard for me. I've got a CRD patrol so use an OBDii ultragauge for boost(which also can have alarms), and a small rectangular EGT gauge down near the shifter. I do like yours better though!

Hopefully you have better luck than I did with the Saas Trax gauges. I had the same two as you, both were replaced under warranty at different times and then a third one played up about 6 months out of warranty.

So mate did you not wire into the dimmer for your instrument cluster (so the gauge dims when you dim the instrument cluster) ? I’m installing redarc gauges and they recommend wiring to a ‘dash light negative’. Just wondering.

[@bigfella6629]

You should be aiming for 15psi on your DI ZD30 unless you have had the ecru reprogrammed to not go into limp mode if your boost goes to high..

[@dingodazz3724]

I run mine on 20psi (max) via a Dawes valve without any reprogramming, only time it goes into limp mode is if the engine is stone cold and I hit those pressures. Every Patrol is different I have found, I used to be only able to run 18psi until I installed a 3" exhaust and opened up all the intake plumbing including new intercooler - now I can run 20psi. The higher the boost the lower the EGT.

[@bigfella6629]

@@dingodazz3724 I have a Tillix setup much the same as the Dawes, my gu patrol goes into limp at around 16-17 psi. Im fitting 3' exhaust hopefully this weekend, I want those nasty EGTs to be as low as possible.

[@Shilo-fc3xm]

Hi, mate. Just subbed. Listen, Always been a Patrol guy but just recently went to Navara after something nice and kinda special fell in my lap at a good price. So this question, while relating to Nav is not actually Nav specific. I have both boost and a Pyro pillar mounted gauges in my new truck. Thing is they're too bright at night and after trying window tint unsuccessfully am reverting to my original plan of tapping into a dimmable circuit at the rear of the dash dimmer button which, by chance is located to the lower right of the steering wheel only about 15 centimetres away from the pillar mount. Doable? Any issues you think may complicate things? I'm sorry I don't yet know your name but Id like to use it. Instead I'll have to just say thanks, mate. Lol. Cheers. Look forward to many more videos (and learning your name :P ).

[@Alex.G]

Hmmmm interesting idea! I had thought of putting tint on mine as well for the same reason, glad to know now that it wouldn't work 😄 I like your idea and as far as I know, lights are dimmable because you are actually reducing the voltage going to them. I'd say probe the wire with a multimeter and see what the voltage is doing. However, the problem I can foresee is the gauges are probably backlit by LED lights, which don't dim the same way halogens do. So really, I'm not entirely sure how your plan will work out, but the most important part is that I don't reckon it'll do any damage to the vehicle or gauges. Can't hurt to try! One more thing that occurs to me as I finish writing this, how about trying some VHT Niteshades paint? You know the stuff people tint tail lights with? You can layer that up as many times as you need to then. The name is Alex by the way, thanks for watching 🙂

[@Shilo-fc3xm]

@@Alex.G Ha. Thanks for the response. Yeah the window tint was ultimately not only too dark during the day to be effective at night but it was tricky af to cut. Seems simple right? I was going to use a protractor to mark it out and it wasn't until I was sitting there about to begin that I realized of course that would leave a hole poked right into the middle of it and you cant use the gauge itself even if you could easily remove and unplug it because you'd get the outside edge, not the inside. Lol. Ok, so what to do? I have to admit I have never been the sharpest tool in the shed but I ended up using consecutive dots measured with a ruler to create a circle but that was shit so spent forty minutes going through every circular object in the house and ended up with a vitamin bottle lid that was exactly right. Haha. Anyway, yeah, so I had four different scrap sheets of tint I went and conned out of my local tint guy for free and even with the three choices it took me three layers to get it to where it needed to be for night driving. A) It doesn't layer very well and B) it was, the following morning as mentioned, then too dark for daylight. So back to the original plan which I like better anyway and see as "the right way to do it". I'm just a little worried its not as straight forward as I expect and will fry something so you lead, ill follow? Lol. I think plenty of people have this problem. Haha. Cheers, Alex. Rhys.

[@trimat2016]

About 20 years too late for me, but better late than never I suppose. The second pod is good for an Auto trans temp gauge if you have an Auto and tow. Engine temps and pressures are better handled by an ECUtalk display for the pre-CRD DI's. If you already have the Dawes/Needle valve you need to tweak it down a bit to control that boost. Better safe than sorry. From memory I had to put a small ball bearing in the pressure line to the boost gauge to settle it down a bit. Not enough to block it obviously, but enough to settle out the spikes.
