Hey guys, it's Rob from Ultimate Diesel Tuning!
Behind me I've got a 2007 Mitsubishi Pajero NS
and it's in for an on-car chemical soot clean
and custom dyno tune.
Before we move on, don't forget to quickly
subscribe to our YouTube channel!
This Pajero is in very good condition for its age
and we do custom dyno tune quite a few of these
each month. They are known to be reliable, they
have a great 3.2-litre 4M41 engine in them,
and are just a solid tourer with really
good towing capabilities.
These engines respond super well to a custom
dyno tune, so I'm super excited to show you the
results that we will achieve from this car.
But before we do that, let's get it in the
workshop and carry out the pre-tune inspection!
This is a vital 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 Pajero has now passed its inspection -
let's do an intake and upper valvetrain clean
before it hits the dyno!
For the best results for the custom dyno tune,
it's really important that the intake and the
associated parts are really clean,
free of diesel soot.
However, there are various methods of soot
cleaning out there, but a lot of them just
simply don't work!
We have a fantastic on-car machine that circulates
at high pressure a powerful concoction through the
intake and into the cylinder head, dissolving the
soot and dissipating it out the exhaust as vapour,
not solid material so it's harmless to the engine.
With no messiness, no replacement parts required,
and it always works!
We have a couple of other YouTube videos on our
soot cleaning method, so make sure you check
them out! Now that the intake manifold's all nice
and clean, it's time to hit the dyno
for the custom dyno tune.
The owner of this NS Pajero uses it as a daily
driver for work, as well as going to the beach and
the bush tracks for a little bit of fun.
In the near future, he will be buying a
camper to go on trips.
It's got a bit of extra weight on board with an
Xrox bullbar; two-inch suspension lift;
catch can; driving lights; roof racks; awning
and a snorkel already fitted, along with a
slightly larger tyre.
He's after more power and torque and less turbo
lag to get his Pajero out of sticky situations on
the beach and on the bush tracks.
So with the tune, we're going to be concentrating
on achieving all of this for him, as well as
taking into consideration what
the vehicle is 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
properly 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 completed the custom dyno tune
on the Pajero, let's have a look at the results.
In standard form, the Pajero had 83 KiloWatts
of power and 305 Newton meters of torque,
at the rear wheels. After we completed the
chemical soot clean on the intake manifold
and upper valvetrain, and the custom dyno tune,
it went to 109 KiloWatts of power and 399 Newton
meters of torque! This represented a 31 percent
gain in power and 30 percent gain in torque, and
this will be really noticeable for the owner when
he's driving in the soft sand on the beach!
There you go guys, another Pajero out the door
with a lot more power and torque after doing a
custom dyno tune and on car chemical soot clean.
The owner of this car was after more power and
torque and less turbo lag and haven't we delivered
this today with a 30 percent gain in torque!
So if you're thinking of increasing the
performance of your diesel vehicle, this is what
we specialise in here at Ultimate Diesel Tuning.

performance centres in Brisbane Gold Coast
and Melbourne, and remember we've got a dealer
network all around Australia! And make sure you
