Hi all,

I am yet to purchase my first Discovery. One of my greater concerns is the fuel economy or lack there of. If I buy one I'd probably get the 3.9ltr v8.

Does anyone know how to make these more fuel effecient? ie. Bigger exhaust to make it breath better etc

Any little secrets?

Cheers

We have owned the V8's for some years. Like you we have looked at every way of making them more efficient without voiding the garantee.
It came down to the right foot, gentle acceleration and keeping the cruising speed below 120 km/h.
Problem with chipping and better exhausts (there are many) is that you tend to then use the extra power and hence gain no fuel consumption benefit!!
We got on our D1 about 390km to a tank town driving and on our DII about 450 km (larger tank and different engine). On the open road we once managed to squeeze 600kn out of the D2.
If the consumption is really going to bug you then dont get the car!! It weighs about 2 tons, is a brick on wheels and does chew petrol!!

I agree with Streak that it all comes down to your right foot as far as making the biggest difference. Other than that avoid weighty gizmos like wraparound brush bar and roof rack, which add considerable weight and drag, thereby worsening performance and economy. keep the inside of your rig freed of dead weight (no, don't throw your mother-in-law out just yet!) If you don't mind a ride a bit rougher than stock, you can also run your tires 10% higher than factory recommended pressure. If traction off-road is not a big deal, choose a tire with lower rolling- resistance tread pattern when it comes time to replace. Be religious with maintenance, such as keeping air filter cleaned (have separate filter for off-road use) and engine well-tuned... Good luck! BTW Streak, I'm interested in getting a chip for my '95 D1 3.9. What are the choices and which one do you recommend?

the gas mileage of the V8 LR is not to far off that of other vehicles of similar type. for example the Nissian truck 4by with extended cab and v6 with the super charger is only good for about 16 mpg on the highway. the dodges and ford are 12-15. these vehicles arent true fulltime four wheel drives and lack (imho) the guts to hold up to the real ruff stuff. anyways in the end, no matter what you drive mileage comes down to how you drive, unless your lucky and can get your hands on a TDi. the nice thing about the diesel it will move about at speeds that would get you decent mileage out of a V8.

Patern12, I live in South Africa. There are a few companies here using the Unichip concept. It is a bolt on to the existing ECU that gets programmed to intercept the various control signals and then alter them.
Try and find a Unichip dealer in your part of the world and ask them what success they have had with LR V8's. Many here have had good success with decent exhuast system with the correct headers and branch. The chip then gets programmed to cater for the better breathing.

Anyone tried this???

a friend just gave me one and said it worked miracles for him, but I�m a bit skeptical.

thanks...

Since you got it for free - why not test install it and testit for us and report back so we can all experience the miracle of the fuel miser.

is that garbage as in
"that F%^#$ thing didn't work on my rig!"
or

?lol...
maybe i will just install, whats to loose?

your 20 bucks

those things have been tested over and over they dont work

tell me this...

if they did do you really think that they wouldent be on every gas vehical in the world?

dont you think they would be required by the EPA as are cats,and vapour recovery systems?

garbage..

I couldn't understand all those big words in the their tech section. LOL.

"...works on the principle of magneto-hydrodynamic technology...the strong magnetic field penetrates the fuel line perpendicular to the flow of the fuel. The flowing fuel molecules collide with this abrupt magnetic field, energizing and dispersing the hydrocarbon molecules in the fuel just before it is burned, enabling more of hydrocarbon molecules to combine with oxygen, which yields more complete combustion of the fuel."

I'd have to ponder the physics here, but I don't think that the petroleum hydrocarbon molecules will really give a shit about an abrubt magnetic field. And even if they did, wouldn't they just mix back up after they left the magnetic field prior to combustion?

I'd have to agree with musky. Throw it in the same box as the tornado air thing, the flux capacitor, the magic hair tonic, and the Swedish penis enlarger. Of course, if you got it for free, and you already have it...there's one way to find out...

These aren't little secrets, but they do get me decent mileage despite having a TJM bullbar and roof rack.

1. Proper tire pressure.
2. New air filter at every oil change.
3. Oil changes at every 3000 miles.
4. Changing the spark plugs at the recommended interval.
5. Changing the transmission fluid at the recommended interval.
6. Driving with a light throttle.

Apart from using a light right foot on the pedal, and the obvious stuff like keeping the air cleaner in good condition, there are a couple of things that can help a little. There is a nice book on Bosch EFI by a guy named Ben Watson, on tuning and troubleshooting such systems. He indicates that the wire meshes in the MAF sensor are a big restriction - they will only trap particles bigger than say .020", or 0.5mm, which wont get through the air cleaner, so what use are they?
Also, on the hot wire MAFs there is an adjustment- hex key under the tamper proof plug. RPI list the range for this adjuster as 1.5V to 1.95V (ign on, not running). This is the basic CO at idle adjuster, which translates to mixture strength. I pulled mine down from 1.9 to 1.5V, and found I got an extra 30-40km out of tank, and it actually seemed to rev better. Doesnt run any hotter or any other noticeable change. On my 97, I measured the V across the first and last pins on the connector.
YMMV

Streak, I looked at the Unichip US site, looks interesting. I like the "piggy-back" setup, since you can go back to stock anytime just by unplugging it. I'll research some more about the effectiveness/reputation. Thanks.

If I were to improve my fuel efficiency, the guys at the gas station wouldn't know my debit card number by heart, nor wave at me on those rare occasions where I can drive past without stopping for fuel!

Not to mention, I wouldn't want to destabilize the mideast any more than it already is!

Blue, it's all pure bullshit. Particles collide with magnetic field lines, jeez, it's funnier than tornado.

mustache, if somebody sells you a handheld tool that converts $1 bills into twenties, will you be still be critical of the "I haven't tried it, but it sounds like Bullll-onee!" concept?

some shit is just plain obvious, no need to test it. besides, just try to find where to install it on your rover.

Let's get back to the "issue at hand" guys, so as far as penis enlargement as-you-drive effectiveness, which one is best? The Fuel-Miser, the Tornado or the flux capacitator?

Magneto-hydrodynamics it good physics. It's possible to move water or other conducting fluids with a properly setup field. If you guys remember, I think the Russian sub in "The Hunt for the Red October" used magneto-hydrodynamic principles in its Caterpillar propulsion system. Beyond that, there are real world applications of the However, other than moving the fuel around a little bit, it's highly unlikely that it will result in better combustion.

Einstein designed a refridgerator that used magnetics to move a slug of mercury which acted like a piston.

Yeah, and Eintstein's pump made a horrible amount of noise and had a propensity to leak ammonia and Mercury into the house. Also, don't forget that he was working in the Vienna patent office when that was developed and he was accused of having stolen the idea.

I have to go to the post office. I have a package to ship back to Sweden.

As for the submarines, many nuclear submarines (guess who makes the best in the world) use pulsejet technology which is essentially forcing water through a nozzle using an electromagnetic field. The advantage of this techology is that it is very quiet. If it weren't for the limitless energy available as a result of the nuclear reaction, the efficiency would be so low we wouldn't even try it.

Tate, hold it. the fucking miser has nothing to do with magneto-hydrodynamics. it's all pure bullshit.

Blue, i belive there are commercially available pumps that chase a slug of mercury around a circular tube. just like an asynchronous AC electric motor. i know of the same setup used for a mechanical gyro.

LOL, never said his was a good design, it's all about the science behind it. As I understand it, his design was never really applied commercially due to other advances.

If you're worried about the cost of fuel, then don't get one - with the cost of parts and/or labor, fuel will be your last concern. Just hope it doesn't need any work while you own it!!

Oh, I�m not worried... I�m a trillionaire!
I made my gazillions working from home stuffing envelopes. My wife was just complaining that Starbucks is really far from the soccer field, so I thought I might find some good advice here on the boards.

Thanks all for the help� I threw Fuel Miser out Kyle�s window yesterday. LOL

as long as the starbucks is less than 1/2 of a gas tank away, you should be in a good shape.
