ECU on the engine
Any display used, either on-board as part of the connector board, or separately plugged in
Additional input sensors such as pitot pressure, rpm from a 2
nd
stage, etc.
Additional output devices such as telemetry, SD memory storage, Bluetooth etc.
Auto Power-Off
The Hub has some intelligence of its own in that it can take a signal from the ECU and isolate
(power down) the ECU battery after a cooldown has completed and the receiver turned off. The
ECU will complete the cooldown process even if the receiver is turned off, it does not need a radio
signal to do this.
This saves the battery in the transmitter and receiver and helps stop the possibility of leaving them
on for long periods accidentally.
Hub installed ambient sensors
Hubs also have installed a pair of ambient sensors for temperature and pressure. These sensors
provide the ECU with data on ambient conditions which the ECU will use to pre-set certain function
parameters to take account of. These include the acceleration and deceleration ramps and idle
speed. In practice this means it is no longer needed for the User to provide any adjustment for
day to day ambient conditions as these are now taken care of by the ECU.
Where an “Auto” option in any menu is offered, the ECU will use the Hub data to adjust the setting
to the most appropriate for the conditions. To use this functionality the user simply leaves the pre-
set in the RUN Menu to Auto.
Hub location
Site the Hub unit in a location away from proximity with the exhaust or sunlight heating as other-
wise its ambient sensors will tell the ECU it is a hot day and moderate settings appropriately.
The Hub is available in several options, all with the sensors built in:
The simplest being the “Lite” option which is just a plain shrink
wrapped board to connect ECU battery, receiver, ECU, fuel
pump and a full colour external display.
The other option is called “Compact Hub” which is housed in a
small plastic box and has a black and white display and small
adjuster buttons, which you can mount in your model to elimi-
nate the need to plug in anything. The screen is very bright
making it easy to observe the start-up on the display from a
short distance through a canopy, for instance.
Bluetooth connectivity is possible using a dedicated module.The Xicoy website,
