300Tdi Tune

[disco_ute]

Well it happen my head gasket blew coming into Mansfield last long weekend.

So I fixed it all got 4 new injectors and got LRA to get it 'Properly tuned' by his diesel guy.

They need the car for a full day ( could be longer if problems arise)

Here is the Dyno read out before and after. Don't worry about the torque figures ( wish they were from the engine ) all figure are @ the wheels. So on paper 17Kw increase @ 40 and so on. On the road :D very happy as most 300tdi owners will know they are a tad sluggish off the line and with an auto when 4th gear kicks in at 80Kmh well basicly it ****s you if you are anywhere but going down a hill. I now find it takes off very well from standing start and I no longer need to floor it all the time to keep up with cars at the lights or in stop start traffic. And when 4th gear drops in it will very happily just keep powering on!!! Even up a hill! I could have just played with the diaphram etc but I want this engine to last and I was told this guy mods the inturnals of the injection pump not just turn a screw or two. not sure about fuel echonmy yet only used 1/4 of a tank and been driving pretty hard. So for those who want a 'real' power increase I highly recommend it! I also dont have that 'hunt at idle anymore and I dont get that BIG black cloud of smoke on start up. Most ppl that play with the pumps blow a lot of smoke under load I hardly notice it it's just a haze I can only see at night.

Thats great Mick, can you give a ball park on price as I realise that it would depend on the car and if there are other problems......?

[disco_ute]

not sure haven't got the invoice yet i think RRP is about $900 that includes dyno before and after parts etc

looks good.
I'd love to know what the pump mods are, I'm sure it'll be better than the 'adjustments' I've made :D

Rick, Dereck at Modern motors in Dungog does the same thing and he's closer to you.

I went and saw Dereck before I left to Kal and he talked me out of it as he made the point of the hot temps over here in summer.D/Gas was what he recommended,he is sold on it.Rick if you go and see him ask him for a drive of his defender,it's modded like mad and goes like a train. Pat

IMO LPG gas tanks take up too much room and most of know that space is limited in landrovers.. and i have drivn a 110 td5 with lpg injection and the for the cost vs power it was crap the chip defenders go way harder anyway.

as far as what he did well everything has yellow paint on it and the smoke screw is all puttied up so if i touch anything my warranty is void

There is a big difference between the Td5 and Tdi.The Tdi gets the biggest improvement out of almost any diesel engine when hooked on gas.There is three that I know of in Kal and all three owners are as happy as. Pat

[rick130]

Mine goes well and gets good economy for something that is as wound up as it is, but a few things in the oil tests are getting too high for my liking (even though it hasn't flagged anything at the lab) and it's something I have to get under control for long term wear control.
New injectors will be going in soon, so we'll see if that changes anything.

Pat;

I recall LandyAndy speaking to a Chap from Diesel Gas Australia in WA at a 4wding and Camping show and what you are saying is contrary to what he was told , I believe he was told that TD5 Engine gets the Biggest Improvement in Power and Torque Figures on Diesel gas.

i may be wrong....

[disco_ute]

any improvment on std TDI would make any owner happy it's the room and cost that gets me. mine is ute and i still would have no place to put a 40 or 70l tanks unless i extened my chassis and put a tradesman tray on it. and the cost of fuel these day who needs to fill 2 different types of tanks!

[PAT303]

I don't mean the Td5 won't improve it will,what I mean is the Tdi as standard can't match a Td5 but on gas they really get up and go.The most common tank fits next to the chassis rail but I have a second battery there so a 40l tank is going in the back across the tub.I find I have plenty of room in my defender.

I've got it fitted to the 300Tdi Defender and must say I don't feel it made much difference at all.
It cost 4 grand and without the 3 rebate I don't feel it would have been worth it.
Plus that awful tank hanging down under the sill looks really bad although it doesn't intrude too much into ground clearance.

Alan, I am very interested in what you wrote. I have also just had the d-gas systen fitted to my 300Tdi and found no noticeable improvement. I 'phoned d-gas and they state that there should be a BIG improvement.

Have you had anyone check your installation? I currently have mine undergoing a check by a different gas fitter - the crowd in Canberra who did mine were pretty slack - coolant leaks, broken bonnet pull, greasy finger marks and coffee cup stains on the guards. Quite apart from the fact that it didn't work......

If you like I will PM you the results after the new lot have had a play with it.

Cheers,

Paul

Hi Paul.
Please let me know if you get real improvement on what you've had done. Mine has nowhere near what I was led to expect or maybe I'm expecting too much!
I'll get back to the installer and get him to give it a check over as soon as I get time to get there.

I've spent too much time having "experts" redo what appears to be shoddy workmanship lately....... the latest "expert" who professes to be of the old school and meticulous in his approach to work, managed to mangle the fan nut by using a pin punch/chisel and big hammer to undo it!!!
He said it was very tight and had never been off but I told him I'd removed it 2 weeks previously with a tap on a spanner in the right direction and he then says I'm telling him how to do his job!!!
Bloody hell, how the hell do we find people who can do what they profess to be able to do when it comes to Landrovers?
I'm not saying the gas installer is of that type as I've seen some of his installation work and it looked great and I'm sure he'll tune it so it does do what they say it will. I'll keep in touch re this.
Alan.
