“Learn R/C”. Teach the ECU to the R/C System
Before the Jet-Tronic ECU can be used for the first time you must program the failsafe
and learn the throttle stick and optionally the auxiliary control positions of your R/C
system.
To accomplish this, complete the following steps:
1. Connect the two ECU servo cables to the receiver. The “
THR
” cable connects to the
throttle channel and the “
AUX
” cable must be connected to a channel capable of
three (3) positions. Make certain that all other connections are made in accordance
with the
Electrical Connection Diagram
.
2. Inspect the transmitter programming, to ensure that dual rates and exponential
functions are disabled, travel is set at 100% (75% if failsafe is active) and sub trim is
set at zero for both channels.
3. While pressing the “
Select Menu
” key on the GSU, switch on the receiver.
Helpful hint:
Instead of the
Select Menu
key on the GSU, the small switch on the LED I/O
board may be pressed instead. This key can also be used to advance through
the “
learn R/C
” sequence (described below). This feature is useful when the
GSU is not available. Keep in mind that the LED’s on the I/O board are the same
as the GSU for “
Standby
”, “
Pump running
” and “
OK
”.

only after the three LED’s display the following blink
sequence:

The GSU display will simultaneously read:

4. This procedure enables a system mode, whereby the stick positions can be learned
by the ECU. When

is released, only the green
OK
LED should
illuminate.
