GAS ON D4D

[D4DLUX]

Well went to a show today and found that you can put a gas kit which run with the desiel fuel to gain more power and better fuel rate. Has any one got this kit?

I also found they run a dp chip and exhaust with this gas kit and get around 800klm to the tank and you also get a $2000 rebate from the gov for this.

I have my dp chip set on 9 the highest setting and its great but i was told today by the same mob that 5 should be the most i should go or i will blow my motor i dont think that is so true but any info on this would be great.

cheers matt

www.dieselgasaustralia.com.au this is the web site

[Hilux Max]

website isnt working. anyway, what sort of performance gains are achievable on a standard D4D?

how much will it cost me before and after the government rebate?

will it cause any undue stress upon the engine, thus shortening engine life?

Thanks

[D4DLUX]

no extra stress on engine run all the same just taking in a small amount of gas though the intake they are saying about 25% power gain though the hole range and and 20% better than fuel.

all i think it is $4200 then $2000 rebate they sell the hole kit for $7000 that is exhaust, dp chip, gas kit, and k&n filter

D4DLUX, was it the same people that sold you the dp chip that told you that running it higher than 5 would blow your motor ?, if so it makes you wonder why they would sell a kit for the lux that goes as far as 9 or even past 5.

[D4DLUX]

No it wasnt that was my point also that even on full noise and chip on 9 there is near none smoke there for carnt be getting that hot cause diesel get there heat and power from the more fuel you put in.

Hi,

I have a D4D with a DieselGas LPG System. I also have a Tunit chip (same as DP, just a different sticker I think?? I bought it through Berrima, then Tunit distributors, now they are DP!).

I can tell you lots about this set up.

Firstly, having your chip set to anything over 7 will mean that at full noise the ECU will go into "limp home" mode as the oxygen and EGT sensors (apparantly) recieve info out of specs and put the motor into safety mode. Just turn the truck off, and back on and then your back in business. I have my chip on 6 and have not had this problem anymore.

Check out this link to the DieselGas website to see my trucks dyno...

Scroll down halfway to see my truck.



I couldn't recomend this kit anymore... just awesome. I get about 1200-1400km from 120-125L diesel, and 35-40L LPG depending on city/highway use.

The power is awesome, and the fuel economy is brilliant.

For a 2+ tonne truck it absolutely flies... I blow off WRX's in 2nd through 3rd gear!!

Heaps of torque and it just keeps pulling!

I'm looking to put a better exhaust on it, as the 2.5" I have now wasn't such a great install.

Give Brad, Matt or Charlie a call at DieselGas on 02 4721 3675. Sydney, they have other affiliates across the country as well.

These guys are very honest and professional. The install they did on my truck is first class, and they actually service my truck now as well.

If your truck is privately registered you'll get the $2k rebate.

No chance of blowing the motor with or without a chip. The LPG injection means that the motor runs cleaner, cooler and more efficiently. The motor will just go into "limp home" mode alot of the chip is set too high.

Hope this helps, let me know if you need any other details.

post up some pics of yours 10K

[chaser]

so it is about the $7000 mark to have this done?
where do they put the gas tank?
thanks

I was looking at this too, but apparently it will void your new car waranty as it is not a Toyota approved modification.... Can anyone confirm or disprove this? Just what i have been told. Looks to be a bloody good mod though!

[Smithyworld]

Any modification that can be proved to have caused the problem will void your warranty. If they can prove that your snorkel cause stress on your engine before it blew up then that will void your warranty too. Its a grey issue that you will oonly eer find out when something goes wrong. Cheers ;0)

For chip and exhaust factor about $2000, depending on who you use.
The DieselGas system is about $4000, less the $2000 rebate.

Tank will go where your spare usually sits, or you can get a triple slim line tank that my tuck up between your chassis rails, but this costs more. All depends on your vehicle and available room.

As for warranty, well depends on what you break. Toyota has added notes to my VIN on their database saying that LPG is on the truck so if I blow a anything to do with drivetrain I'm pretty well on my own. However if the electric windows stop working or the headlights fail etc this will all be covered. Definately is a grey area... worth considering on a brand new truck especially.

that is cool wouldnt that great beating a wrx in a hilux i have my dp chip set on 9 all day and drive is pretty hard and doesnt go in to limp home mode. can you tell us more about it all.

[10K]

Here is my experience with "Limp Home" mode (LHM) on my D4D hilux so far...!
Basically, and especially in the hot and humid weather of summer when you have the LPG switched on, and have the chip set to 7 and above, and give the truck a bootful of the line through 1st, then 2nd as you hit about 3000-3300rpm and are about to find 3rd you hear a "poof" and all of a sudden you have lost all of your horses and are in LHM.
The truck will only do 10-15kms and you have to turn the truck off, then restart to have normal function from the ECU and motor.
Back the chip off to 6 or below and you can drive it hard all day with no fear of LHM, with the LPG on.
A few points here.
1. I usually run the chip on 7 through winter and don't take it over 3300 rpm ish as your torque curve falls away and your best going to the next gear anyway.
2. The reasons why you hit LHM when using LPG (never happens with LPG off) are varied and I am certainly no expert. As the LPG is feed in on the intake side of the intercooler it affects the oxygen sensors for the motor. Also the chip will vary fuel flow through injectors outside of standard ECU settings and this combined with the extra cumbustion taking place will also throw the ECU parameters out of spec, thus LHM.
Basically the LPG helps achieve a higher burn % of diesel in the combustion chamber. New common rail motors have a pretty good burn rate anyway due to excellent injectors and fuel pumps, but with LPG you burn upto 95% of diesel.. so less smoke, more power, better fuel economy. Motor runs cooler and the LPG reduces the intake air temp from the intercooler and your motor will run cleaner and you can extend your service intervals. LPG has more benefit on older tech diesel motors, though still a great addition to the new ones too.
www.dieselgas.com.au has a great FAQ and technical section that will better explain all of this.
Hope this helps. The LPG is easily the best mod on my truck. Cheers

sounds like you work for them mate haha i will look into it a bit more thanks for the info .

"I couldn't recomend this kit anymore... just awesome. I get about 1200-1400km from 120-125L diesel, and 35-40L LPG depending on city/highway use."

dosnt the standard diesel get 10l Per 100km?

so 120L of diesel is 1200 km anyway?
yet it also needs another 34L of LPG?

i seem to be missing something.
cuz the figures don't seem much different then normal fuel consumption on the diesels?

[TOMUCH]

Josh, you may be missing the fact that with that same fuel economy you are getting a shite load more power....I have read about gas on Diesel Engines before, and its pretty good... I believe that you can also have it switched so that you can give it some gas when you want it and have it turned off the rest of the time... I suppose it would be like having 20 odd Kw at the push of a button... 10K, are you in a position to confirm or deny that?? Would be interested in finding out for sure... Cheers TOMUCH

[10K]

jcarter... Your point in regards to fuel economy from the info I provided holds some water but there are a few extra factors worth explaining here.

As TOMUCH rightly added there is a bucket load more power for roughly the same milage as a standard truck.

I know a fair few blokes with new D4D Hiluxs from single cabs to DC's, and they all very different fuel consumption. Most report around 600kms per tank, best and worst 570-650km per tank, reading some of the other forums there is marked differences between members as well. I don't know what "standard" fuel economy is!!

My truck has 33" tyres, also has about a extra 300-500kg loaded into it combining accessories, tools and materials for work. These things considered... extra power, weight and tyre diameter I think that the fuel economy is outstanding.

As for your question TOMUCH regading LPG push button activation... YES. There is a small switch on the dash next to the 12V outlet (Also LPG tank guage) where you can switch it on or off. I always leave mine on.

One other point on the LPG, you get a bit of over rev in between gear changes (manual), as the gas continues to feed into the intercooler while your off the accelerator (ie no diesel being injected). Nothing to much to worry about, nor is it that noticeable... made worse on the new Hiluxs with their long throw gear shifter!!

At the end of the day the LPG is great if you do a lot of miles and will keep the truck for a while, as it is quite expensive to install.
If your on the hunt for more grunt it's ideal.
Cheers

Here is a pic of the switch and guage combined.

Fits neatly into standard auxilary button/switch void.
