Ignition/injection management details:
Fuel Injection (new)
Originally developed and tested in conjunction with Bryan
Slark of Slark Race Engineering and Jon Lee of LynxAE and Steve Harris of
Harris Motorsport using their dyno facilities.
The POLESTAR fuel injection system has been specifically
designed for the A-Series engine. It can be used in either single point or
multipoint sequential mode (requiring a cam sensor). It will operate with
turbo/supercharged and normally aspirated engines. When running in
twinpoint sequential mode injector timing is carefully controlled to ensure
correct mixture balance between the cylinders sharing an inlet port.
The system consists of a management ECU, a magnetically operated
crankshaft sensor and a timing disk which attaches to the crankshaft pulley
of an A-Series engine. (it can be modified to fit many other types of
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.
All POLESTAR ECUs provide a standard rev counter output, and the
fuel injection ECUs can control the engine cooling fan, fuel pump and idle
control value.
