MoTec M4, AUX 3 as PWM fan output

[LOLA-Christian]

Hi all,
I am working on an old M4, where the plan is to use AUX 3 to control cooling fan (PWM),
Everything works fine when I am using "test output" (200Hz. from 10% to 90% (below 10 and above 95 it is "off")
But when I am in "normal mode" (with correct values in table etc...), and simulate changing ET (=X-axis) nothing happens, output AUX 3 is always =0.

Have I missed something.....?

Basic question, I know, but how many ignition outputs are you using?

Two Ign Outputs (33 & 34)

Got information from Support, everything is OK - AUX 3 is only activated when system is "active" (= engine is running)
