Hi guys, it's Rob from Ultimate Diesel Tuning!
Behind me is a Toyota HiLux N70,
and it's in for a few upgrades.
This one is a 2015 model with the 3-litre D4D
engine in and fitted with the 5 speed auto.
It's one of the last N70 HiLux models made
before the N80s were released.
Before we move on, don't forget to quickly

Today, we're going to carry out one of our
on-car chemical soot cleans to it; fit one of
our trans packs to it; as well as finish it
off with a custom dyno tune.
But before we do any of that, let's get it in the
workshop and do the pre-tune inspection.
This is a crucial part of the tuning procedure
here at Ultimate Diesel Tuning.
This inspection is to ensure the engine is in
good condition, all fluid levels are good
and there are no fluid leaks.
The HiLux has now passed the inspection,
so let's get the soot clean done!
When it comes to removing restrictive tar-like
soot out of the intake manifold and other
engine components, a lot of the methods on
the market just simply don't work.
So for this reason, it's really important that
you choose the correct method.
We have a fantastic on-car chemical machine
that does the job extremely well!
Our machine simply sprays a concoction of chemical
into the intake to dissolve all the soot and then
it goes out the exhaust as, vapour not solid
material. It is harmless to the engine.
Afterwards, we'll give the engine an oil flush and
engine oil and filter change to finish it off.
This HiLux has already had an engine oil catch can
fitted to it, which will really help prevent that
soot build-up and contamination
in the manifold in the future.
Now that we've completed the soot clean to the
engine, we're now going to fit the Trans Pack.
These are brilliant and we'd recommend these
to all N70 HiLuxes in auto, as they're a real
game-changer for the way the vehicle drives.
Like the V8 LandCruisers, the N70 and N80
HiLuxes are also notorious for their erratic
transmission shifting behaviors, particularly
over 100 kilometres per hour. The transmission
just doesn't seem to want to stay in top gear
and keeps fluctuating between fourth and fifth
gears, which is very frustrating for the driver.
This behaviour causes excessive fuel consumption,
as well as also, with the changing gears up and
down, excessive oil temperature in the gearbox.
To counteract this, we'll fit a
transmission lock-up kit to it.
We have another detailed YouTube video on the
Trans Packs, which we did on a 200 Series.
Our Trans Packs for the HiLuxes are very similar
to the 200 Series Cruiser ones.
Now the soot clean has been done and the Trans
Pack's been fitted to the HiLux, it's now time
for the custom dyno tune!
This HiLux is used as a daily driver, it also hits
the beaches and goes off-road. On top of that,
it also gets away on adventures on the weekend
with a big camper behind it.
The owner of the HiLux is about to hit a big
adventure with the family and the kids, and is
heading out to Central Queensland with the
camper on the back.
As you can see it's had a fair bit of
external work done to it, adding
a bit of weight to the HiLux.
It's had a GVM upgrade including a 2-inch lift;
it has an ARB bullbar; a winch; driving lights;
canopy; roof racks; drawers in the rear
and a long-range fuel tank.
The owner of the HiLux had already fitted a chip
to this vehicle, and he wasn't happy with it, so
it's here today to get more power and torque
and just get rid of that lag down low.
So with the tune we're going to be concentrating
on achieving all this, as well as taking into
consideration the weight of the vehicle and
what he's actually going to be towing.
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!
We've now finished the custom dyno tune on
the HiLux - let's have a look at the results!
When the ute presented to us, it had 89 Kilowatts
of power and 295 Newton meters of torque. This
was with the chip being fitted to the vehicle.
We then removed the chip and ran the vehicle up
in standard form and it had 88 Kilowatts of power
and 275 Newton metres of torque, at the
rear wheels. As you can see, it's about a
20 Newton metre gain in torque and about
one or two Kilowatts, which as you can see
it was only really at the start of the rev-range
where there were any gains, which were very
minimal. After we completed the custom
dyno tune though, it went to 118 Kilowatts of
power and 395 Newton metres of torque!
And this will be really noticeable because you've
(now) got a 43 percent gain in torque and a
34 percent gain in power!
So you can really see the difference between a
custom dyno tune and a chip, and I'm confident
that the owner is going to be certainly happy
with this when he drives out of here today!
So there you go guys, there's another N70 HiLux
we've done some work to here at Ultimate Diesel
Tuning. This customer wanted less turbo lag,
more power and torque, and won't he notice it
with an extra 43 percent gain in torque!
And it will drive a lot nicer on the highway
with the Trans Pack installed!
