Just picked up my TD5 Disco tonight....My thoughts

[SPROVER]

Well i have to say im really impressed with how the TD5 goes.Just picked it up tonight and drove it home.It has 293 000km on it but you wouldnt know.I just filled it up with a fresh tank of diesel and im looking forward to some decent fuel economy after coming from a 95 ES V8 Disco.

It drives really nice and is pretty comfortable as well.I had heard alot of stories about the TD5,some good and alot bad :p. So it was a bit of a gamble.I didnt really expect it to get up and go that good, so is there anyway of telling if it has been previously chipped or not.I'll be posting some pics when i can soon.
Cheers
Chris

The amount of turbo lag is a good indicator. Std has a noticeable lag, remap has very little.

[strangy]

Have a look at the ECU ( beside the jack and battery) it will likely have a sticker from the tuner if it has been upgraded. Eg TRS, BD, etc and some sort of "void if removed" tamper label.

I can here the screams now but..., std v8 of your old trucks era are no match for a TD5 and a well tuned TD5 makes many a bigger engine look slow.

.....and light the blue touch paper and stand well back. :D

I have a 95 Disco V8 too. Mine has done the same k's on original drive train including motor as your td5. The only mod is a scorcher ignition. Mine still goes hard and is very quiet. Its an auto but sits you back in your seat.

Hope it goes well mate.

The BD ECU's have a small round white sticker on the case with some kind of reference number* written in pen on it. Otherwise no other markings or void stickers of any kind.



*Don't bother asking BD what it means - I discovered that they can't/won't tell you :angel:

[Redback]

You should know if it's chipped, my chipped D2 with my 1.4t camper on would pull away from a mates 3.9 V8 going up hill, used to annoy him no end and still get 14l/100ks:D

Welcome to Td5 land! Just look after it and you'll love it:D

Yeah thanks Wardy.Had my first drive to work in it today and it really is quite nice to drive.Still getting use to the long travel accelerator pedal feel though:D And im wondering if the fuel gauge is working properly.It hasnt moved yet :p.:)

[wardy1]

Looks like a trip planned for Sunday in wombat.... come along and find out just how good it is:D

I would have like to but with mothers day and all that i wouldnt be able to.Plus its only got cheese cutters on it.I really need some mud tyres.:D

TRS modified ECUs also have a similar sticker.If the ECU part number starts with NNN it could have been remapped with a Nanocom.

Well everything is still going well so far:D I have to say im really happy with the fuel economy.I have done 400 km now and only just hit half on the fuel gauge.This would of just about emptied out my D1 V8 by now:eek::p.

I have noticed one thing though.Sometimes there is a slight surge when on light throttle at 80 km/h.Is this normal? I have an EGR removal thing coming soon and some silicon hoses:) I have also bought a TM-4 for the important stuff and a boost gauge to see whats going on.

Where should i connect the line for the boost gauge? Next after that will be an EGT gauge and then probably a remap.:twisted: My list just keeps getting longer.What i want to do when money isnt so tight:o

Nanocom
2 inch lift
longer shocks
mud tyres
remap
CDL connection

And probably alot more:D

Hmm, 400 is what I get normally by half, and that's with me giving a good caning playing tail gate with an obnoxious Audi Q7 driver who did the same to me at 120.... :whistling: :angel:
I used to get a surge at 80km/h that got worse then disappeared, hasn't come back since.
Perhaps check the ECU harness for oil in the red plug :)
I'd put Nanocom at the top of your list, it's probably the best investment any D2 owner can make.
Followed by CDL and the remap :)

[PhilipA]

I get an on-off "shunt" sometimes when easing off then onto light throttle on the expressway at say 100-110.
I believe it may be the EGR valve opening and closing just on the edge of operation.
The fix is to drive around it and not jusst lightly put the foot down but be a bit more positive.
sseing all my sensors seem to read properly , that is my guess.

I have been giving it a bit of a bootful since i got it as well.Just testing how it all runs :D Yup the nanocom is the first thing on my list to get next.I'm sure it will come in very handy from what i have read on here.And i will check the oil in the harness on the weekend.I think the previous owner had a new injector harness put in.I'll have to check that one out.

Yep thats exactly what i get.I just wanted to check if that was a normal thing with the Td5.And i did exactly that, just put the foot down a bit more and it was all good :)

After reading about the various retunes possible for EU3, a nagging thought keeps poking up in my mind.

That is ; What use is a retune for more power as it seems that in my use of towing a camper up a big hill when I would want the extra power I couldn't use it because my EGTs would get too high.

I have seen it reported that even with a standard tune the EGTs get high towing on hills.
Aside from the vicarious thrills of showing off by accelerating hard and throwing lots of black smoke as in the other current post, how does a tune change the EGTs downwards so that they are no longer a worry, or do those who have an EGT gauge end up applying about the same power going up a long hill as someone running WFO on a standard tune, limited by their EGTs.

Assuming no other mods like bigger intercoolers, or staright through and bigger exhausts which would tend to increase power anyway.

Like I said, mine just went away.
It wasn't 80kmh specifically, it was that rev range. Also did it at 50kmh.
Began to think it might have been the throttle position switch but it disappeared and it ain't been back.
My harness was bone dry.

[Sharkee]

Gday Sprover I've had 2 x TD5's and they go quite well for a diesel of that size. Depending on what mods have been done and whether its manual/auto etc I think one could expect anywhere from 700 to 950km per tank. My first TD5 I towed a 19ft full height 2t van to Hervey Bay and back to Vic and although I pushed the boundries to the limit was getting 550km out of a tank towing. I consistently got 530 to 550 for around the 80-85litres. I know not a good thing to do but ran it to the fuel light and then quite a bit past that. I had jerry cans if I got into trouble. They really are a remarkable vehicle providing you get a good one. Sorry to rant I just thought it might of been of some interest.

[Disco Muppet]

I kick myself if I don't get at least 700 out of a tank, and I don't hang around.
If I stick to 90, it will happily run past 900kms.
One interesting thing I've found, IIRC the light on the Td5 is supposed to come on at something like 7.5 litres left.
I've filled up when the light just came on and still had about 17 L in it...
hmmm....

[SPROVER]

My driving has mostly been in traffic on my way to work.I haven't done a full tank yet since I bought it.But so far I'm happy with it.

[Sharkee]

Yeah I found that mate the light varied a bit but found at times mine came on at just under quarter and at times just off empty was weird but never seemed to be the same. I suppose terrain etc would have a bearing on that.
I filled it on one tank and took 91litres :eek: :lol2: couldn't have been a lot left. Not towing I think mine was averaging around 800-850. I had got 940 and done as bad as 700 with a lot of little short trips

A very good question Phillip, i am looking at getting the remap for my D2 as well. I have read in other threads and posts that changing down a gear and lowering the revs lowers the EG Temps however that does sort of defeat the purpose of having the remap to give you more power and torque. I would much rather be passing that other brand 4WD while towing a trailer uphill in a decent rev range rather than revving its guts out and them looking at me saying "It sounds like that large british marque automobile with the aerodynamics of a brick has a rotary in it...."

I am on my second Disco (my first was a 03 TD5 S) and my second is a 04 Classic TD5) and i love them (i shouldnt have sold the first one). They have both had their idiosyncrasises (big word for the day) but after going away from LR im glad i came back.

I am guessing that with the normal day to day driving etc that the extra power and torque will be worth it (i mean who wouldnt want to increase your power from 101kw to 170 in one simple upload from a NANOCOM) and then i will need to fit a EGT guage to monitor the Temps when towing a trailer and going up hills etc once i have had the remap. I guess like the vibration in the rev range around 2150-2250 and the throttle response from standing, you get used to it and you drive around it. I mean im still learning that i need to give a bit more positive pressure to the loud pedal which is hard as im tight as a fish's b*m, so what seems like wasting diesel is a hard thing for me to do mentally. (I dont even have a wallet as my kids might ask for money when were at the shops.. :D..) . I am noticing that it does drive smoother and less vibrations etc when i drive it that way though.

Looking forward to that remap and then the large quantity of gadgets i will need to monitor it.

[SPROVER]

That's one off the reasons I want to put in the EGT gauge so I can see what it is like driving with the standard set up and what sort of temps it would get to.Then what the temps are after a remap.With the same sort of driving.Has anyone got any figures of before and after remap?

[OffTrack]

Strangy posted up some EGT tests a while back comparing stock vs trs chipped, with and without intercooler, at standard boost and increased boost.

http://www.aulro.com/afvb/technical-chatter/133503-td5-alive-i-c.html

Stock IC and boost settings with a chipped or remap ECU virtually guarantees excessively high EGT's under load.

If you limited the EGT's to same as what you'd see with a stock setup you'd see similar power levels because EGT's are closely related to the Air Fuel Ratio. If you drive to higher but still safe EGT's you'll have more power available.

I think what Strangy's tests indicate is that these remaps don't contain the required data to correctly fuel the motor under heavy load with stock intercooler and std. boost. This results in an overly rich mixture which causes elevated EGT's. Adding a bigger intercooler and/or increasing boost have the effect of increasing the air density in the inlet manifold meaning more air is available to fully burn the injected fuel which in turn reduces EGTs.

I have had 3 tanks through mine so far for consumption of 11.6, 11.9 and 10.7 l per 100 km.
Each tank has had one trip to Sydney down the F3 and back and the remainder my 20Km commute to work in West Gosford from Avoca Beach.

This compares to approximately 18.5-19.0 L per 100Km for my 3.9 RRC, commuting only as it was too expensive to take to sydney.LOL.

[thexprinter]

Just returned to Qld after Tassie tour in my 2000 disco td5 all up Between 6-7 thou K.s........ 10l per 100k was not a prob however towing a tandem van 2ton the best we get is 16l per 100 then lots of head wind or big hills up goes the consumption again..........Love my disco....thexprinter:)

[rover-56]

And im wondering if the fuel gauge is working properly.It hasnt moved yet :p.:)

It won't move until you have done ~100km. Then you should get another 700.

[elshano]

jeez I wish this stuff was as prevalent for the v8s as well! I'm lucky to get 500km to a tank :D

[SPROVER]

Well i have just gone through my first tank since buying it.The light came on so i went and filled it up.It took 79.66 litres of diesel and i done 655 km.So that works out to be 12.1 L/100.

I do a 20km trip each way to work with alot of stop, starting in between.So im really happy with that considering i have been giving it a bootful here and there to see how it goes :D

[Yorkie]

recommend for fuel pump longevity refill at qtr tank not when the light comes on. :cool:

[Blknight.aus]

Also treat the tank to a dose of fungicide every service and if you head to the snow switch to alpine diesel early if you can or garage the car and keep the tank warm.

What is this dose of fungicide you speak of? :eek::D
