Unichip for the Cruiser

Had a look at that - and I know that Graeme Cooper (Newtown, Sydney) fits them to 4WD - $1200.

Want some experiences with the chip from people...

Dunno what the right hand scale is - as you say 10,000??? Possible nm x 10 - that would fit into the scale.

Cruiser power does seem a bit peaky - care of I thnk the cam and breathing - though with 4 valves one would expect better breathing. So it would have to be cam...

Don't want power or torque to peak to high for a heavy offroad vehicle - otherwise you and you boat will be climbing up a hill at 180 km/hr or not at all... Like lots of low down grunt (would have preferred the diesel turbo, but this time round can't have everything I want ;)

mm by 10 ..ok i can see that

85kw @ 4100 rpm isnt this too low?

And if you compare the charts agaist an eaton blower on a 4.5 something does not stack up. look only at standard figures...who is right ?

Now - see if this works: Nope it don't. Can't paste pictures here??? Oh well...

I think that the Unichip one is more correct - I am familiar with these charts from my Rangie. A rule of thumb for a constant 4WD or AWD, 45% of flywheel power goes to the wheels. Petrol cruiser is what, 165 kw? 45% of that is 74 kw. That fits. If measuring off the rear wheels only (locked centre diff and disconnect the front drive shaft) I would expect another 25 - 30 kw. I would say the Eaton figures are rear wheels only...

I have seen similar figures on 2wd and 4wd engaged on dynos.
Engaging front diff can loose up to 20% of total power due to more ineffeciencies in getting the power to the ground.

An interesting read. I own a Mercedes Sprinter van, motor is a diesel with common rail injection. Very interesting motor, considering its size (2.2 litre) and output (97 kw). It is a very capable tourer, maybe moreso than the 4.5 litre Landcruiser and weighs empty about 250 kg less...

Thielert in Germany are modifying diesel engines for use in aricraft, 1.7 litre (from the A series Mercedes) producing 99 kw. That is pretty awesome capacity/kw ratio. Wih I could have something like them in the Cruiser - however this would require super-filtration of the fuel for starters. One dose of bad fuel and your wallet will be in a very unhappy state, let me tell you...

Stop me - I'm rambling...! :)
