Help in setting up the RMP sensor for orange cube for a 3W gasser ICE

ArduPlane Plane 4.3
1

running 4.3.5 with orange cube i am … i have tired a lot to read the rmp on the gcs (mission planner) but i seem to get only RPM2: -1 as the reading…
i have done everything by the book and have see the arduwiki page too but nothing seem to work… need some help from anyone who has dealt with IC engines… below is the sequence
A) Aux out pin 6 from the orange cube is SERVO 14… hence have set
servo14_function = -1 (for GPIO)
C) rpm2_type = 2 (for GPIO)
D) rpm2_pin = 55 (for AUX6)
i have powered up the orange cube but i still get to see RPM2: -1
anyone can show how its done as i have tried to ask in quite a few places without any answer…

thanks

what worked our for me is a below… and important note for 3W engine owners…
tacho wires - yellow and white coming out of the ignition module orientation is as below
WHITE is the Signal wire
YELLOW is the power wire
servo13_function -1 GPIO
servo14_function -1 GPIO
ice_rpm_chanel 1 rpm1
rpm1_type 2 GPIO
rpm1_pin 54 for AUX4
rpm2_pin 55 for AUX5
rpm2_type 2 GPIO
I am able to get the RMP1 reading perfect now… also have set up the RMP2 for reading…

regards
