Chip Tuning or Remapping
Remapping and "Chip tuning" as it is commonly
known, is the art of modifying the standard ECU (Engine Control Unit) software,
which is stored in the factory engine management system, otherwise known as the
ECU or ECM (Engine Control Module). In order to increase the power-output of the
engine, it is important to change the timing and amount of fuelling, ignition
timing, and turbo boost on turbocharged engines. By adjusting these parameters,
the engine will have the utmost efficient combustion required for power and
economy. An increase in power output of about 30% can be achieved, combined with
a smoke-free vehicle and improved fuel economy of about 5%.
What is involved?
Normally the original software in the ECM is
read first and stored as a file. This file is then modified and then programmed
back into the ECM, overwriting the original software. Only the parts of the
software essential for improving the performance of the engine are altered. The
software is read and programmed to and from the ECM via the OBDII diagnostics
port, so there are no physical changes at all. Even if the ECM has to be removed
from the car for access, it's normally a non-invasive process of reprogramming
the engine computer, known as bench flashing. We do not alter any of the
diagnostics systems, or the engine idle running, or any areas which would affect
the MOT emissions. This makes our ECM upgrades 100% service compliant, and 100%
UK emissions compliant.
How does remapping and chip tuning compare to
a tuning box for a diesel engine?
Tuning boxes are add on devices that work by
intercepting the signals between the ECU and the sensors and fuel system in the
engine. Some tuning boxes intercept the sensor signals fooling the ECU into
thinking that the engine is doing something different to what it actually is,
thus making the ECU add more fuel. Other tuning boxes work by intercepting the
output signals from the ECU and thus modifying the fuel control. Either way, a
tuning box will only increase the amount of fuel that is added. A tuning box has
its place on many modern vehicles where it is either not possible to remap or a
remap has not been developed. Due to the fact that the tuning box is only
‘skewing’ the fuelling and not increasing turbo pressure, the gains are often
significantly less than a remap.
Alternatives
Some makes of vehicles cannot be tuned by
modifying the software on the ecu, in these circumstances the alternative is
using a tuning box.
PLEASE NOTE, WE WILL NOT TUNE
EX-POLICE CARS
Why HLM? Added value of
course.
- Full diagnostics and checks before and
after the ECM upgrade (Where possible)
This is a very important part of the tuning
process, many cars that are not brand new and have miles on the clock could have
some sort of problem that will effect the overall performance of the car and you
the customer may not know about it. Using our specialist diagnostic equipment we
can detect problems before tuning. However any additional work needed maybe
chargeable.
- Dyno Jet Rolling Road Power Run before
and after the upgrade (Where possible)
The car will be put on our dynojet rolling road
before we perform the upgrade, this is normally included in the price of the
upgrade and is a valuable part of the service as it not only shows the standard
horsepower of the car and then the modified horsepower of the car. Therefore
verifying our power claims. Your power plots can be provided on paper and
electronically.
We are truly independent and source our tuning products from the best for
each application.
