Can
DKTUNING
remaps all kinds of cars?
We can remap most cars of year
2000 or newer. You can find it in
Vehicle List
here. For those we cannot
remap, we now have a new range of solutions which can be found
in
www.dktuning.com/newproduct.htm.

Can the Service Centre or car dealer detects my car being
remapped?
No, it cannot be detected.
Service Centres use diagnostic machines which is unable to pick
up any differences. A remap is done without any device
installed, hence, the invisibility. The new map is encoded with
your car identities such as chassis no, so everything remains
‘stealth’.

Will the remap voids the car warranty?
Remapping is untraceable to
most car makes so it
should not affect your warranty with an exception to VAG Group
vehicles.
BACK TO TOP
Is the work guaranteed?
Yes, we perform the remap with
the highest degree of care. All works carried out by us are
guaranteed. However we do not warrant against wear and tears or
damages your engine produces during your daily usage. Those
are covered by your manufacturer’s warranty.
BACK TO TOP
Will the fuel consumption increase after a Remap?
As a matter of fact, fuel
economy will be better after a remap. The engine has better
power and torque, which means your engine works less harder
hauling the same car weight mass. As long as you don’t whack the
gas pedal to the floor all the time and drive like a lunatic,
your car should drink less fuel under normal driving. A remapped
car should not consume more fuel than stock.

Am I going to lose the new Map if I disconnect
the battery or replace battery?
No, the map stays in the ECU.
The only way to loose it is when your car got stolen.
Jokes aside .... you will only
lose the mapping if you replace your ECU with an entirely new
unit. If that really happens, don’t worry. We will install it
back for you!
BACK TO TOP
Can I have the
‘remap’ be shared in more than one car?
Being Malaysian myself, I know
what goes through your mind. Unfortunately, it is impossible.
Each map is ‘made’ for a particular car with its identity such
as chassis number and software version embedded into it. It
would not work in a different car.
BACK TO TOP
Will my car have better acceleration and top speed?
Yes! With the increase in
engine performance, your car would perform much better. We
usually would remove the speed limiter in your car during a
remap so your car would definitely achieve a higher top speed.

I heard that remapping is not cheap. Is that true?
If you have owned an older car
before, you would understand the following paragraph better:
Many mistaken the process of
Remapping or ‘ECU Tuning’ to the job similar to your favourite
foreman in the 90s. It involves tweaking the carburettor for
air/fuel mixture and idling and then, adjusting ignition timing.
He then would go for a test run, and readjust as necessary till
he thinks its okay. Technology evolves in the 90s and then came
the machine which reads out Air Fuel Ratio from sensors affixed
at the exhaust, providing the mechanic a better visual for more
accurate adjustments.
Gone are the days of manual
adjustments. Modern cars today came equipped with complex
computer controlled ignition and fuel mixture system, adaptive
and computerised automatic gearboxes and now, the advent of fuel
and power efficient systems such as VVT and Double VANOS. All
these engines are closely looped and linked to the ECU which
controls everything to make the engine works as efficient as
possible.
The only ‘perfect’ way to
alter these modern engines is through a Remap. The process and
the R&D required for developing maps for the ECU is time
consuming and costly. Each map developed is unique to that
particular car make and model. It cannot be used for other model
even for the same make. Tuners today do not make simple
adjustments like the olden day’s foreman of tweaking the
carburettors and ignition, but a whole lot more parameters than
that. It is not an easy day for the Tuner to adjust all
parameters to squeeze out the hidden power of the car engines
with so many settings to tend to. There are passwords and
protocols to crack too. More so, to ensure all the
settings altered work harmoniously while maintaining or even
improving the mileage.
Your remapped car would have
the map in the car forever, hence, its a one-time investment for
a lifetime thrill!

Are all remaps
the same?
Absolutely not! Each company has their own tuning 'recipe'. Some
remaps gain more power than the others. There are some good
remaps done on a car but with a sacrifice on drivability. There
are also companies who charge cheaper but lesser development
works done on their map recipe.
Let's take a
Bakery as an example. There are bakeries selling expensive buns
and pastries which are very delicious while some sell at very
cheap price tags which has texture and tastes slightly better
than a cardboard. All bakeries serve good spread of buns and
pastries, but not all had a perfect recipe. If some little part
of recipe doesn't go right, the dough may not rise well, burnt
on the surface while uncooked in middle, texture too rough, too
sweet, etc. But well, the bakery still sell.....buns and
pastries, just that it doesn't taste good.
At DKTUNING, we have once been in your shoes and we know just
how difficult it is to choose the right company to remap our
precious ride. We ensure all our performance maps are best
possible in all areas whilst never sacrifice on our service
level and professionalism in handling all our clients' cars. Our
years of experience allowed us to perform very successful remap
with the least problems.

I found other
companies charging cheaper. Can you match them? Or should I go
with the cheapest?
Let me relate a recent
personal experience. I went to a tourist foodstreet hunting for
Fried Oyster Omelette. There are 3 stalls there selling the same
thing and I remembered 1 of them is tastier than the others,
with their own homemade, well-matched chilli sauce. All I want
is to order a plate of the best one because 1 plate is all I
need. I used all possible memory to pinpoint which one was the
good one. I asks the next tables for recommendations and surf up
food blogs on my Android. I found the right one eventually and
filled my tummy happily.
The price per plate wasn't relevant to me at that time. I
did not shop for
the cheapest price. I feel its about the same when it comes to
selecting a remapping company. A car needs only 1 remap to be
perfect so
deciding on the best one is very crucial, sometimes, cost isn't
the primary deciding
factor. I could order a second plate of the omelette if the 1st
one wasn't the best
because it costs less than RM10, but you can't simply do that
for a remap.
We know we are not the only
company providing remapping services but we have a very good
recipe for the ECU! Good recipe are developed at a cost,
fortunately, we do not charge you a fortune for a piece of this
good map. Our remapping price starts from RM1,500. You may find that our prices are very reasonable as we
are not the cheapest yet some others even charges nearly double
of ours! We give you quality product and unrivalled level of
service at reasonable price.

How soon will I feel the effect of increased performance?
Instantly! Although you might
get more power gradually as the car is driven for a certain
distance for the ECU
to adapt with the new map.
BACK TO TOP
Can my car take the additional stress from the increased HP &
Torque?
Certainly! All parts in your
car is designed with a wide tolerance of safety. It is quite
impossible to reach the limit of your car purely through remapping.
BACK TO TOP
Do you guarantee the HP & Torque gain claimed?
We guarantee there is gain
after the remap, and you would definitely feel it without even
need to dyno the car. However, as not all cars are built equal
from the car manufacturer, every car would perform and improve differently.
A lot of people asked for guarantee but we simply cannot do
that. No remapping companies in the world would guarantee such.
BACK TO TOP
Can I reverse the remap to stock car?
Yes, we can do that upon
request. However, I bet you wouldn’t want to after you have
driven a remapped car.
BACK TO TOP
Why don’t manufacturers sell cars which are
remapped?
When vehicles are
distributed throughout the world, most manufacturers adopt a one
map fits all policy. This one map has to take into account many
different factors that are necessary for each export country.
Areas such as climate, emissions, fuel quality etc all have to
be considered by the manufacturer. It is simply not economical
enough for manufacturers to customise according to each market.
Another reason is for manufacturers to stage their different
models according to the specs and target market. A particular
car model may have 2 versions and wear different emblems at the
boot cover. Manufacturers are able to sell these two models at
different trimming levels, engine output figures at different
prices, but they essentially have the same engine. Secret is
purely in the mapping.

What is the difference between Piggyback and
an ECU Remap?
Many mistaken an ECU Remap to
installing a Piggyback. The difference is pretty big, as a
matter of fact. As I am not a Piggyback expert, I shall try to
provide a neutral insight and information obtained from
experience and other websites.
There are many
types of piggy backs in the market, each of them has their own
unique functions so it is quite difficult to comment the
weaknesses in piggyback specifically. To put it simply, a Piggy
Back or A/F Controller basically takes LIMITED number of signals
from your sensors and modifies them to trick your ECU into
reading a different value. The ECU then would attempt to boost
the engine performance by means of the modified signals.
There usually is an immediate
power increment felt after the installation of a piggyback.
However, we met many who installed piggyback
reported to us their car returned to stock car performance after
a certain period of time. The period ranges between 2 - 6 months,
and some as short as 2 weeks! This could be possible because the
modern ECU are intelligently designed to go against and adapt to
the faulty signals it receive from the Piggyback module.
An ECU Remap operation replaces
the original Map inside the ECU with a completely new tuned
version. The ECU does not need to dwell with fault inputs but
has all modified parameters in the new map working harmoniously.
This is why a remapped vehicle experience same or even better
fuel economy with increased yet smooth performance gain. Power
gain is usually much higher than a piggyback installation, permanent, still maintaining good Air/Fuel Ratio and elimination
of flatspot, which is something a piggyback does not provide.
Piggy back modifies perhaps less than 5
parameters whereas an ECU Remap involves tweaking 30-50 or more
parameters. When a piggybacked ECU is struggling against the few
fault inputs from the Piggyback module,
Check Engine Light
may appear on certain cars.
A bit more
technical info for the Car Nuts / Knowledge Hungry:
Well doesn’t a A/F controller and piggy back computer control
ignition timing?
Yes but not effectively. An A/F Controller takes readings
from your MAF/MAP sensor and alters them trick your ecu into
reading a different signal. And since all your maps are tied in
together, your MAF/MAP sensor signal also will move where your
ecu reads its ignition timing on the map. your MAF/MAP is not
only used to maintain air/fuel, but its also used by the ecu to
determine load, and load is used for determining timing advance,
this has the side effect of fooling the ecu into advancing
timing beyond what is safe. These readings will also effect
where your cam angle is, which more then likely will not be at
the optimal angle for your boosted application.
Newer piggy backs like the e-manage ultimate can control your
ignition timing separately from your airflow readings, but there
are still catches. You are able to change ignition timing maps
but the e-manage simply changes the output signal the ECU sends
to the coils. The problem is the ignition timing numbers are not
always consistent with the changes you make to the load sensor,
whether its your MAP/MAF sensor. So you are guessing the timing
numbers. The stock ecu also has multiple maps it can run for
different conditions so you are not always consistent with the
tune.

What about Tuning Box?
Sometimes also called
Performance Box, this device is to be affixed in the engine
bay, usually applicable only among Light Commercial Vehicle (LCV) or 4x4
pickups with Turbo Diesel Engines.
The idea behind
the diesel performance box is to intercept the
signal between the vehicle's ECU and fuel injection
system via the common rail or fuel injectors. To
understand how the tuning box actually works it is
important to understand how the diesel engine works.
In a diesel engine it is only air
that is drawn into the compression cylinder, this is
then compressed and reaches a very high temperature.
When the piston is nearing the end of its cycle fuel
is injected into the chamber and ignites due to the
high temperature of the air. This gives the power
to drive the piston down. There is extra air left in
the cylinder after this process, sometimes as much
as 50%.
Looking at the concept behind,
turbo settings are not altered hence, turbo lag
should still present. Boost level is maintained and
torque curve does not shift but improved because
more fuel is burned. All other effects of remapping
are not available through installation of Tuning
Box, unfortunately.
However, there are benefits with
Tuning Box as compared to a remap. Its easy
installation makes it popular for DIY enthusiast as
well as performance / 4x4 shops. The box is also
transferable to another car of similar engines.
DKTUNING also supply Tuning Boxes
for all the 4x4 Turbo diesel engines. We would
only propose this option for cars we could not remap.
Does it matter
if my car is Automatic or Manual?
The software
upgrade from us is very well adapted to the existing type of
gearbox, to avoid trouble and provide the best performance,
acceleration and drivabillity. We can remap vehicles with both
Automatic and Manual transmission.
I found
very cheap price of remap on certain websites for Mitsubishi
Lancer GT and Proton Inspira. Why the big price difference?
In the late years, this
specific remapping tools could be obtained at a reasonable
price. Hobbyist saw the opportunity where they could copy
out tuned map from pretuned car, and reload this into other
cars to make a quick buck. They are not worried of a poor
job because no one would complain over such a cheap price.
CHEAP QUICKIE
First of all, the cheap remap
does not do a remap. They basically would flash in a 'so
called' tuned map they extracted from other pretuned cars
and load it into cars that goes to them for remapping.
Usually they won't even read out the original map. Meaning,
if you want them to flash back to original, they won't be
doing it because they never save in the first place. All it
takes is 2 mins.
- No real tuning/remap done
- Original map will be lost
- No Warranty or Guarantee
- Car software identity will
change following the source car
- File could be under or
overtuned for your engine and gearbox
- Probability your car could
not start due to the difference in software version
Real remapping involves copying
out the original software from the car ecu, tune the
software with the right knowledge using the right template,
and load the performance copy into the car. We will have two
copies of your car maps. Real custom remap like what we do
takes about 2 hours, provided if the template is available
for your ecu version. If it is not available, we got to send
the software over to get the template fabricated first
before we could start tuning. All parameters are carefully
tuned, datalogged your car, and retuned till perfection. We
even calibrate the file perfectly to match the two most
popular petrol octane quality in the country, so you benefit
the difference of using RON95 and 97.
Would you be tuning blindly
without a Dyno Machine?
Most of our tuned software are
pre-developed on dyno machine. We will have to fine tune a
little further for different car and fuel condition, with the
aid of datalogging machines. Our remapping involved years of
experience both locally and international influences in order to
perform a good result.
We take
responsibility to all our clients' cars hence, tuning blindly or
recklessly is definitely a no no. We do not take risk. We know
absolutely well what we are doing.
