Hi guys, it's Rob from Ultimate Diesel Tuning and
behind me is a 2011 Toyota LandCruiser
76 Series and we've done a fair bit of work to it.
Before I move on, make sure you subscribe
to our Ultimate Diesel Tuning YouTube channel!
We carried out an on-car chemical soot clean to
it, to get the inlet nice and clean, and we are
yet to carry out the custom dyno tune,
it'll go on the dyno shortly for that.
Plus, we upgraded the standard clutch, and we
carried out the all-important pre-tune
inspection right at the start.
So let's have a look at what we did to this
LandCruiser in more detail!
When it comes to removing restrictive soot from
the intake manifold and other engine components,
there are several different methods on the
market that you can choose.
Unfortunately, most of these just do not work.
Due to this, it's really important that you
choose the correct method!
We have a fantastic on-car chemical soot-clean
machine that gets the job done.
Our machine sprays a concoction of chemical into
the intake to dissolve all the soot, and then it
all goes out the exhaust as vapour, not a solid
material. It works extremely well
and is harmless to the engine. Afterward,
we'll give the engine an oil flush and an
engine oil and filter change to finish it off.
So with this LandCruiser I've got the guys
to remove the top hat off the inlet manifold
so we could film the before and after results
and show them to you.
So as you can see, this LandCruiser had a
lot of soot build-up, given it's 10 years old,
but it's only done around 50,000 kilometres.
Imagine what it's like at 100 or even 200,000
kilometers on your LandCruiser!
So that's the soot clean been done, so let's
talk about the clutch.
Clutch upgrades are essential with every
LandCruiser, as the standard clutches in
them simply will not be able to handle the
huge gains in torque that we will achieve
with these engines. The clutches of
choice here at Ultimate Diesel Tuning
are the Xtreme Outback Series.
They have the factory pedal feel to them and
they can easily handle the extra torque!
Alright guys, now that I've shown you in more
detail the soot clean and the upgraded clutch,
let's get it on the dyno and
carry out the custom dyno tune!
This 76 Series tows a 2.5-tonne van
behind it and it's only used for touring.
It's got 33-inch tyres; bull bar with winch;
spotlights; roof racks and awning; so there's
a fair bit of extra weight on board.
The 70 Series LandCruiser is very underwhelming
in power and torque in standard form.
The owner is chasing bigger improvements
and better drivability.
So, with the tune we're going to be concentrating
on achieving all of this for him as well as taking
into consideration the weight of this vehicle
and what it's being used for.
First of all for our custom dyno tuning procedure
we carry out power runs on our all-wheel-drive
dyno in standard form, to get base power and
torque figures at the wheels. This is how we
know which vital information and figures we
are starting off with for each vehicle,
as every engine is different.
We also test to confirm the engine is running
correctly with no underlying mechanical issues,
then we carry out the custom dyno tune.
Our tuning process involves altering the software
within the vehicle's factory ECU. Using our
specialist software, our engineering team is
able to carry out recalibration of numerous
engine control parameters, such as torque
limiting, desired torque, fuel injection maps,
boost control and many more. Via the use
of our dyno, we can accurately test these
software changes to each individual car,
whilst data-logging the engine's performance
after each software revision. This process sees
multiple tunes tested until optimised power and
torque is achieved, based on the vehicle's use.
It's truly a customised tuning process!
So, we've now completed the custom dyno tune on
the 76 Series let's have a look at the results!
When the LandCruiser presented to us,
it had 92 Kilowatts of power and
320 Newton Meters of torque, at the rear wheels.
After we completed the custom dyno tune, it
went to 133 Kilowatts and 602 Newton meters
of torque. This represented a 45 percent gain
in peak power but an 88 percent gain in torque!
Which will be really noticeable when
towing your van.
Well there you go guys, another LandCruiser
70 Series custom dyno tuned here at
Ultimate Diesel Tuning.
So if you're looking to improve the performance
of your diesel vehicle, this is what we specialise
in here at Ultimate Diesel Tuning.
So give us a call or drop into one of our
performance centres in Brisbane, Gold Coast
and Melbourne and remember, we do have
a dealer network all around Australia.
