All ECUs include Bluetooth connectivity!
Connect and map fuel injection ECUs with no wires. Just pair the ECU to your Window laptop and connect with the mapping software. Stay connected several metres away.
Can also stream engine data (RPM, Temperatures etc.) over bluetooth to many different dash boards (using Autronic SM4 V1.09 protocol)
POLESTAR HS Fuel Injection System can be configured to operate
in a number of different modes.
cylinder 4 injector fully sequential.
point multi injector.
to 8 cylinder 4 injector batch injection.
a special mode has been designed specifically for the Mini A-Series
engine allowing sequential operation with 2 injectors, where
the injector timing is carefully controlled to ensure correct
mixture balance between the cylinders sharing an inlet port.
system will operate using a standard "missing tooth" crankshaft trigger wheel
and VR sensor as fitted as standard on many production engines.
Many trigger wheel patters supported (36-1, 60-1, 24-2 etc.)
It can also be configured to use an existing POLESTAR trigger
disk and hexagonal sensor. It will operate with various CAM sensors
either hall effect or VR type. It also supports the standard crank and
camshaft trigger arangement on a Yamaha R1 5PW motorbike engine. Various
other sensor are required depending on the system type. These
are typically a throttle position sensor, MAP sensor, water temperature
sensor and inlet air temperature sensor, usually the ECU can be
calibrated to use the engine's existing temperature sensors.
With the addition of a wideband lambda sensor controller the system will
run in closed loop fuel mode making mapping semi-automatic, and
giving much tighter control of fuelling whilst running. Both the Innovate LC-1 or PLX Devices SM-AFR lambda sensor controllers are supported
- ECU has 4 coil
drivers and 4 injector drivers which allows support for up to 8 cylinders
with batch injection or full 4 cylinder sequential injection.
(Each injector driver can drive upto 3 high impedance injectors).

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 Fuel Injection 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.
POLSTAR HS systems just require a USB connecting cable (or bluetooth pairing) and the
mapping software which can be downloaded for free from the downloads page. This software will run on most Windows versions from Windows 98 to Windows10.
It is simple to use an allows Live mapping
of all engine parameters with the engine running.
