Dials/guages

[landi41]

Hi Gary, all my additional gauges are electrically operated, no probs with readings and all are genuine LR

Listen guys, i have a great idea......... I saw a Sea Harrier for sale on Mil Web........... I'll bet there are enough guages in that puppy to satisfy the most discriminating "gaugeists" amongst us...........

And as an added bonus Western is an aircraft maintenance specialist.............. I'm sure he could help with the installations :)

Right Ralph ? :)

Now Lads on a serious note..................

Many "marine " guage suppliers have a wide range of items applicable to both petrol and diesel Land Rover engines......... such as ..........low oil pressure and overheating warning "buzzers" and some that even shut the engine down automatically...........

In the heat of the "off-road warfare" battle, where your eyes are not always available for guage scanning i'd suggest looking into those items that do "the job" for you....................

I must say I do like the functions and automated colour coded displays of the Omega kit for the EGT, very smart.

I wish they did a round 52mm Coolant Temp gauge with all those functions, that would give me a lot more piece of mind regarding the above paragraghs.

My only reservation on my initial perusal of the gauges on that site is the size of the units. I'm really gonna struggle to fit something like that my very congested cab area.

The i32 gauges are 25.4 x 48 mm so take up less room than a 52 mm round gauge. The could also measure coolant temperature.

A "Newbie member" still requiring some help please.

can I ask what EGT gauges & sensors (ie. manufacturer) you guys are using?

Also, would like some help & opinions with the choice of electrical or mechanical/capillary type gauges for water / oil temp & pressure??? Also which manufacturers to steer clear of and which you might recommend.

cheers, gary B)

I recently installed the Thermoguard EGT kit and am very pleased with it. The min/max function is good as it means you don't have to watch it all the time to know what peaks it is reaching. My highest so far is 609, that was after about a minute and a half full throttle up a steepish hill in 4th.

Not to bash that system, but I would seriously suggest using a 3mm thermocouple and not a 6mm one as is in that kit. The thermal inertia of a 6mm TC is too high to see short term peak.

I design/build/operate high temperature process equipment for a living and this includes running a lot of test equipment so have a very good feeling for the reponse time of a thermocouple. 3mm is perfectly adequate for this installation and will give much better response.

Hi guys, once again thanx for the all replies, very appreciated.

My head is buzzing with all the info and help.

Hi Western, those pics and info are very helpful mate. I nipped round to my garage to have a look at the oil filter on my Td5, I think I'm going to struggle to fit the combination temp/pressure sensor like you have. I will try and post a pic later so you can see. I have that second additional centre fuge (sp?) oil filter that sits right infront of the first filter. I think the combination unit may clash. Once i get a pic up you might see what I mean.

Due to a lack of experience i'm struggling to take all this info & choices of kit in. I'm now trying to get my head round where and how to install the different types of senders, what types to use. Obviously the Td5 has lots of monitoring devices attached to it already, I don't want to conflict with any of the OE. I've had my head under the bonet looking at where the original senders are and where I might be able to add others. This doesn't come naturally to me so I have to take my time and will have to ask lots of questions.

Hi Red90

Apologies, I didn't study the spec hard enough and made an assumption of the size from looking at the pics. Considering all that they do, they're quite dinky. Looks like a promising option regarding the EGT and even the coolent Temp monitoring.

I'm wondering about what types of thermocouples (I hope that's the correct term) are used. Where the best position will be for installing. Which form of installment, ie. drill and tap or I see options for drilling a hole and then welding or brazing a threaded fitment on.......not sure.

I must say that I have wanted to start sorting this side of Landy out for quite a while but kept putting it off. I have gots lots to read and digest, lots of planning to do before any purchases are made but I feel a little more confident having found this forum. Thanks for all the help so far and not making feel stupid. I'm sure I'll have a lot more questions as the thinking process proceeds, hope you don't mind.

I have seen another thread from the Devon 4x4 forum that has a similar theme. One of the Belgium guys with a Td5 has installed a Sparco unit which looks quite smart. I have no idea of the cost or how well it actually works but I have had a little nosey on the Sparco site. There doen't appear to be much technical info regarding the unit but they do list the 2 optional types of compatibe senders.

i'll include a link to the above mentioned forum for anyone that cares to have a nosey.

Kind Regards to all that have shown an interest,

and once again, thanx for reading my ramblings, gary B)

Hi JST

I have just realised that I have un-intentionally hi-jacked you original posting

As I posted earlier, I was kindly redirected here from another Difflock member because my posting there was along the same lines.

I apologise if I appeared to have taken over with my quest for info but I just got a little bit carried away.

I'm hoping I haven't caused anybody to feel as though I've stepped on any toes as the new kid on the block with loads of questions. I think we're all looking for relatively the same advice in a common quest.

I just thought I should show curtousy to you and the other guys.

I also want to say that I'm really pleased to have found this excellent forum. It's refreshing, informative and friendly. Very cool IMHO

A BIG HELLO to everyone from me.

Kindest Regards to you all, gary

[JST]

no worries,

following it all with interest.

i am still trying to sort my central dash design so that will dictate what space i have available for guages although think it will go:

main dash: speedo, rev counter, coolant temp, fuel

centre dash: voltmeter, engine oil temp, oil pressure, underdrive oil temp (possibly)

Ralph,

do you know or can you remember what size the thread is on your oil temp semder as shown on 'modifed part page'?

also what washers did you use? LR ones? and sizes?

excellent wealth of info thanks for digging it out.

Not to bash that system, but I would seriously suggest using a 3mm thermocouple and not a 6mm one as is in that kit. The thermal inertia of a 6mm TC is too high to see short term peak.

I design/build/operate high temperature process equipment for a living and this includes running a lot of test equipment so have a very good feeling for the reponse time of a thermocouple. 3mm is perfectly adequate for this installation and will give much better response.

Watching the thing in action it is clear there is a lot of thermal inertia when you nail the throttle to the floor and keep it there (the "peak change rate" is probably about 20 deg per second and I'm sure the EGT goes up quicker than that - when you back off suddenly the displayed EGT keeps rising for a few seconds), but equally once it gets close to the max on sustained full throttle it more or less stops moving, from 600 to 609 probably took 15-20 seconds as did the previous peak I achieved of 603 a few weeks earlier. I see where you're coming from with the argument and I'll pass it on to Ian who makes the kit, I guess the display has to be properly calibrated to the TC so it isn't a case of just finding one and changing it. Any comments/perhaps we should start a separate thread on this subject & it could later be added in to the one that is now in the tech archive?

Sorry haven't got a clue of the thread type not having to suss that out was why I used the genuine parts, they just fit [the parts are actually for the 2.5TD engine, but as the filter head is the same on a 200TDi,it made the job very easy]

And as an added bonus Western is an aircraft maintenance specialist.............. I'm sure he could help with the installations

Right Ralph ?

Yep that's right but only on airframes & powerplant, I'd still need a electrician to suss those gauges out

[Gary]

Hi Western

I only have photos of my Landy on my laptop.

Is there anyway of posting pics direct to forum without have an URL?

Regards, gary

[JST]

only ask as i was thinking of using the temp sender in a G box as well ( well under drive - it gets bloody hot)

any idea on copper washer size or did you reorder the ones specific off the sheet for each mounting?

[western]

Just picked some copper washers of suitable size when I collected the parts from my local Landy parts supplier

don't think so, I use

Just because I can:

Tacho

Vacuum gauge

Water temp

Air temp

Enrichment

Injector pulsewidth

Throttle position

Battery voltage

Mixture (exhaust gas oxygen sensed)

Barometer

Engine run time

One box:

Oh did I mention I can tune it from this too?

This is a better installation although not as portable.

[Turbocharger]

Watching the thing in action it is clear there is a lot of thermal inertia when you nail the throttle to the floor and keep it there (the "peak change rate" is probably about 20 deg per second and I'm sure the EGT goes up quicker than that

I bought one a couple of weeks back and I believe from Ian there's some internal damping in the unit - certainly playing with Will Warne's EGT gauge at Sodbury it 'updates' as often as the Thermoguard unit but will happily skip 20°C in a single update. However...

nail the throttle and the numbers spiral upwards rapidly, but when you approach a reading which reflects the true gas temp, the rate of change reduces. I'm not sure if that's internal damping, the effect of the mass of the thermocouple (6mm as mentioned earlier) or a true reflection of the gas temp slowly rising as the intercooler heat-soaks.

I am concerned that the peak temps I see on the gauge aren't what the turbine sees because the gauge doesn't follow transients well enough - maybe a lighter thermocouple would address that.

[Ex Member]

For a 6mm TC, that response rate seems normal. There is nothing you can do but put in a smaller one. A 3mm unit will repsond 4 times faster. Ther eis no need for a 6mm unit, a 3mm 304 or 316SS sheathed type K TC will last forever in that application.

[Gary]

Hi Red90

Going back to the Omega Gauge units.................

it's not so much the front facia dimensions that are the problem but more the depth. They're quite deep at 125mm to mount on top of the dash. If I were to mount ontop can you program the actual brightness of the LED display so it's not in your face over powering?

Where are you looking at installing your unit when you go down that route?

I had a quick read of the manual. There is no mention of brightness adjustment.

I'm planning on mounting in the center gauge area (middle lower part of the dash). There is lots of depth there. It may depend on how new your Defender is as they have done many different things in that area over the years.

One other thing. The model I quited does not appear to have the relay outputs. You need to get that as an option which increases the price somewhat.

[Gary]

Hi Red90

Thanx for the reply mate, appreciated.

Also considering another gauge and just wondered if you might have any suggestions........

I'm after another gauge for monitoring the air pressure from my ARB compressor. Can you get a dial/gauge in 52mm round standard dash fitment?

Kindest Regards, gary

[Ex Member]

Sure, lots of gauges for air pressure. Many use the VDO Vision series. They have a 150 psi mechanical one.

Here are many options

[apologies for thread hijack]

Fridge, could you estimate the cost of the various components + time involved in installing Megasquirt to do all that?

[FridgeFreezer]

Markie:

Ready built ECU: £170

V8 EFi setup minus ECU & AFM: £10 (sodbury)

Wiring tail: £25

MegaView built: Maybe £50 ish depending on display and case used, VFD modules such as here cost a lot more than LCD.

This is a very rough estimate assuming you're fitting it yourself.

[MarkieB]

True it is that Megasquirt is quite good on price, I think I'd need to make it possible to work on the vehicle/s during the winter to cope with the time involved in calibrating, writing code to achieve all the various tasks, etcetera though, I foresee hours of careful tuning

[mattD110td5x]

Now Lads on a serious note..................

As per usual our canadian friend is right

Light plane instruments are... well light for a start,

they come in 52mm (2"1/4) and also 1"1/2 and most have

built in alarms.

Have a look at the Smart Singles TC-1 Quad EGT;

I think you could get 4 thermocouples with 4 ranges and 4 alarms so;

EGT, Water Temp, Oil Temp and Transmission temp

for only $239 AUD?

I also like the look of turbine speed, vertical speed, and the G force meter
