‘Live’ ECU
Remapping
Austec Racing have been industry leading tuners of the
standard fitment ECU in TVRs for many years.
Therefore, our Rolling Road ("dyno") remapping service comes complete and
backed up by years of experience. The tuning process
starts with a base run on the dyno to determine current
horsepower output and the air-fuel ratio.
 Once this is complete, we then start tuning the car.
This involves a complete optimisation and rewrite of all
fuel and ignition maps. You will typically see a
significant improvement in acceleration, throttle
response, part throttle driving, cruise fuel economy and
finally total output.
Once the process is complete, a final dyno run is
carried out and you will be given a dyno printout
showing the final output figures, this will show
flywheel horsepower*, power at the wheels and torque
output.
You will also receive a second printout that plots both
before and after figures, you will then see graphically
what has changed as a result of the remapping service.
Our
remapping process is a completely live service, but what
does this mean ? Many other tuners have the ability to
make changes to standard ECUs by removing a chip from
the ECU, uploading changes and then reinstalling the
ECU.
As you will appreciate, this is very time consuming if
you want to completely rewrite both fuel and ignition
maps. We have the specialist tools and abilities to
directly communicate with the ECU whilst it is still
installed in the car.
The mapping process is therefore ‘live’ as all changes
are real-time. When the process is finished, the new
ECU maps are installed into your ECU.
The
final part of the process is to road test and make any
changes, the dyno cell is effectively a road simulator.
However, we always finish the mapping process by means
of road test to make sure all is as it should be.
*Flywheel horsepower is calculated by the addition of
the horsepower at the wheels and the horsepower lost
through the transmission. Our Maha LPS3000 dyno
calculates realtime transmission loss by means of a full
transmission rundown at the end of every dyno run. |
