yellow4 and white5 wires are in communication with
#5 ........... System start-up: 12V = system on.
#6 ........... Flow sensor signal: 0.5 to 4.5V
#7 ........... Water level sensor: 0v= empty, 5v= not empty
#8 ........... Fuel injector (-). not direct injection.
#16 ......... IDC% signal: 0 to 5V
#17 ......... MPS signal: 0 to 5V (signal conditioned)
#18 ......... IDC% to the water injection valve
#23 ......... System power: 12V (switched/fused)
???

The white wire of the green harness is not amongst the test points.

On the last page but one of the user manual, all pin out from the controller is described.

How many channles on new model AUX? If there are 3 ( IAT EGT A/F) of them, then how to control them? There is only one AUXFX trimmer. Should be 3 too?

[Richard L]

These is only one but can be used for anyone of named sensors. IAT is inverted.

I think RICHARDL has mentioned very useful points that you can get benefit of it

#30 .......... system status (signal level). 0v =off 3V=standby 8V=triggered.

I can only log 0-5v source. Any alternative? I just want to log when WI starts.

Regards.

When you can log 0-5V, 8V will be read as 5V (clipping by your logger)

Your log will look as:
0, 3V and 5V.

I don't quite see the point of data logging the status of the aquamist, the data is pretty static, once triggered. It woild be more useful to log the water flow (via the yellow wire of the user port). It is a 0-5 signal.
