Holly smoke . . . how much power do you want . . . .

I have heard reports of them fitted to both the 4.5 & 4.8 with excellent reports. Would like to do that with my 4.5.

Reports were from the Yahoo Patrol list.

Never have too much power I recon. Better fuel economy would be nice to.

My 4.5 uses roughly 20/100 l City (Canberra) , 15 - 17 /100 normal highway , and 20 - 22 towing my campertrailer.

Trying to dig up some old info, but cant get their Search function working properly.

I recall it improved fuel , by about 2 or 3 /100 , which when towing would make a fair diff. I would suspect your 4.8 would be better then the 4.5 though for starters.

I'll keep looking.

Thanks for that Flappan, which sort of fuel do you use std or pre and would that make a diff i am useing std at the moment and what sort of camper trailer we tow about 1.5 wet and 1.1 dry.
i would take 20-22/100 but mine is a bit lower than that we are getting at best 23/100 and thats on the highway, so we need to get it down to around 20/100 and with the fuel we have on board 220 and 4 jerry should get a range of somewhere 1000k-1300k which would be nice and would mean that one could stop and have a look around instead of just making it to the pump. Somtimes you can just see the needle drop on the guage when towing uphill.

I just use standard stuff. I used Optimax for 5 tanks , and couldn't see any difference. Apparently the Top BP stuff (98 octane or something) is supposed to improve things , but there isn't a BP close by.

My camper is quite light compared to yours . . . 650 loaded (no water tanks on it yet), so relatively , you probably aren't doing too bad.

I only have standard Tanks (130l) and range is 650k's with trailer.

If you have the cash, then a Unichip would help.

Hi Flappan ... Shell Optimax, BP Ultimate & Mobil Synergy 8000 are all essentially the same fuel.

I see no or very little difference in economy while running any 98 around town. Certainly not enough to justify the extra cost. But I do see upto a 10% improvement when running on freeway or when towing in our Jackaroo, and I will start filling up with 98 2 or 3 tankfuls ahead of any planned trip.

Replaces the factory Microchip in the Vehicles ECU.

Supposed to improve power and fuel economy.

From the reports I have heard . . . works well.

A re-mapped (re-programmed) computer chip that controls your fuel delivery etc.

Runs the onboard computer (ECU) that controls the engine management.

Powerchip is another brand.

Oops . . . pays to reread and check things before speaking . . .my fault sorry.

Unichip is a fully programmable engine management system which allows 408 optimised fuel and ignition parameters to be channelled through a vehicles standard factory ECU to deliver maximum power, optimised drivability and improved fuel economy.

Don't confuse replacement eproms in the computer with 'interceptor' units, The unichip is an 'interceptor' device that allows you to modify the various ecu control signals going to the standard computer, effectively re programming the fuel maps, ignition curves , boost cut , fuel cut etc... Can also be removed and the vehicle sold as stock. Great units, get one fitted by an experienced tuner with a good dyno. Just killin time till easter...............go and play in the dirt, instead of workin in it......

I asked the Sydney dealer in Newtown about fitting one to my Frontera. Cannot remember the name but he does a lot of Land Rover work. He was quite upfront about it not working on the Frontera because of the variable valve timing, (I think that's right?). He has a Dyno and tests them before and after. Might be an idea to try and trace him down for an honest answer.

uppy,
If you have 3 small boys you have plenty of time i would swap the 4.8 for the boys and your age anyday.
Goodluck with them they will bring you as much pleasure as the 4.8 and i am sure you will get the big 4.8 some day.
All the bestGoing soon can't wait
