Gas installed in the D2

[walker]

I finally got the D2 installed with LPG. I got the Landi Renzo system which was installed by Range-Rov in Melbourne. Range-Rov also do all the servicing on the Disco so it made sense to use them.

I researched a fair bit before the install and I still think the OMVL Dream system may be the best around but the Landi system is definately not far behind, if not equal with it.

The install under the bonnet is very fairly neat with everything using existing bolt holes so no new holes had to be drilled for mounting the gear, except of course the drill and tap for the new gas injectors.



They installed the filler for the LPG in behind the petrol filler flap which is great. The other installers I looked at all put the filler in the lower quarter panel.



I had scuba tanks installed and as part of the install they make a false floor over the tanks which makes everything nice and neat. The tanks are 70litre with 62litre usable.....or something like that.





The price was $4100. After driving it so far I can't feel any difference between petrol and gas as far as performance goes. If anything, it is a bit more responsive on gas but I reckon the mapping on my Disco has been bad from new and it has always felt slow.
The price is about the same as the 3 other installers a talked too but none of the others could do Scuba tanks. I have been told that power will be down about 5% on gas but when they dyno'd it the torque was up by 20nm on gas in the 2000-3000 RPM range. Fuel economy should be 5-10% worse on gas as well but I will let you know what the real worl figures are when I get them.

NOW THE BAD POINTS.

1. Unfortunately they found my radiator was full of mud and had started coroding so i had to buy a new one.

2. They tried to bill me for more than I was quoted because apparently it cost more than they expected or took longer or something. Anyway in the end after a bit of an argument they came to the party and agreed to the original price


3. One of the other reasons I went with Range-Rov was because when they talked me through how they do the install, I was impressed that they put the gas ECU inside the vehicle rather than under the bonnet. this way it is protected from mud and water just like the standard V8 ecu is. When I got the Disco home and started looking over everything I went looking for the ECU............I find it in the jack compartment under the bonnet.


But all that said, I would definately recomend Range-rov for a gas install.

Good news Adam,and good pics too.
A series 2 has been on the shopping list, but the d1 is going great at present.
I look forward to reading the economy feedback once you have done a few klm's.
One thought though.
I can't help thinking the bad points 1 and 2 are related.
I have never heard of a radiator corroding, maybe I should get out more, but are'nt they either Aluminium or copper?
Did you see it?
I don't have an axe to grind with Range rov, they have given good service on the odd occasion I have been there, but it does'nt sound right to me, but I could be wrong.

I am not sure about the coroding question but I do know a few people that have had similar problems. I have kept the old radiator as a spare and the bottom section was very clogged up with mud.

I will clean it all out and it will do a a spare if I ever need it.

No.1 & 2 are not related as I paid extra for the replacement of the radiator on top of the gas install.

Why did they need to take the radiator out (thus finding it faulty) to fit the LPG system?

Good question really - don't the injected systems run at full pressure to the injectors? and so doing away with the need for engine coolant to keep gas from freezing? On a regular system the coolant would likley be dropped but mayb not so on this?

[walker]

????????? No idea. I assumed it was done as part of the standard install.

They also did a 30,000km service at the same time but I can't imagine that would include checking the radiator.

I am glad that they did because when I saw the old radiator I don't think it would have done a good job cooling the engine with it on gas.

I do admit I did treat the Disco pretty badly in it's first 10,000km of life. It has been places like Walker's Tk and anyone who has done that track will know just how hard it is on the vehicle.

Now that i have the Rangie the Disco only gets used for touring and everyday driving so hopefully I won't have as many problems with it in the future.

Aluminium (and Copper) both Corrode (oxidise)

Add heat and moisture to the equation and its well under way to dying.

Bugs body acid really rips into the tubes and can kill them double time.

Never heard of a radiator corroding? Man its the common reason for replacement...

System is "Vapour" injection, it still has a converter in the coolant line to vapourise the LPG...

The LPG then sits behind "injectors" (solonoids) mounted to the manifold and fired by the supplimentary ECU as required.

So no, not true LPG injection.

Adam, a Unichip is what you need now, that way you can have it set your ignition system up for optimal performance on LPG and petrol as there are multiple ingition mapping scenarios. Ignition system for petrol is not conducive to good performance on LPG, Regards Frank.

The LPG has its own ECU...

As for D2s the Unichip gains very very little, no more economy, marginal power increase...

Most of the performance increase on a Unichip D2 is the weight reduction to the Drivers Right rear pocket.

D1 is a different story, however why fit a Unichip when a complete aftermarket system is not much different in $$$.
