addition to our Fuel
we also supply ignition only systems. The basic two dimensional
(2D) ignition-only system provides a simple mapped ignition for
carburettor based engines. The engines advance curve can be tailored
to the engine with ignition points at every 500 rpm up to 15000rpm.
POLESTAR systems has been used successfully for several years
by Mini Miglia and many other race formulae.
coil drivers allowing support for up to 8 cylinders. Can also
run in single coil mode retaining the distributor for spark
distribution. Ideal for history formula cars where distributor
has to be retained.
crankshaft trigger via standard 36-1 trigger wheel, or original
POLESTAR style trigger wheel.
adjusted with 8 load sites at every 500 rpm from 0-15000rpm
with full interpolation between sites.
'smooth-cut' rev limiter.
POLESTAR HS ECUs provide a standard rev counter output.
Turbo package with 'Boost Retard' feature including integral
1.5bar MAP sensor internal to the ECU.
mapping software for MS Windows
adding a throttle position sensor or using an optional MAP sensor
(internal to the ECU) the system can operate in 3D mode. The ignition
timing can then be set based on both RPM and throttle position/manifold
pressure. This allows an engine to produce more power and run
more efficiently with part throttle openings. A typical 3D ignition
curve is shown opposite.
Managment System - Boost Retard
turbo or supercharged engines it is often ideal to be able to
apply a controlled amount of ignition retard as the boost pressure
increases. This is important to prevent dangerous detonation which
can quickly melt pistons and destroy an engine.
The POLESTAR HS Turbo Management System employs an integral manifold
absolute pressure sensor (MAP) which constantly measures the boost
pressure (0-1.5bar, or 0-22psi) boost). The system can then be
configured with between 0 and 5 degrees of ignition retard per
PSI of boost pressure. This value can be configured in 0.25 degree
increments for super accurate engine timing under boost conditions.
The calculated retard value is subtracted from the base advance
figure in the engine map. This gives safe smooth delivery of power
from a turbo or supercharged engine. This functionality is available
in both our fuel injection and ignition only ECUs.
POLSTAR HS systems just require a USB connecting cable and the
mapping software which can be downloaded for free from the downloads page. This software will run on all Windows versions from Windows 98 to Windows10.
It is simple to use an allows Live mapping
of all engine parameters with the engine running.
