What is the blue wire and the green wire that there is a manual in your?
Where do I hook up my black wire?

Re: Datalogging HFS3v3
 

This option is for HFS4 only.

1. You can connect the Black wire to the blue wire of the green harness.
2. Upon the EGT voltage exceeds the AUXFX trimmer setting, it can either turn on the Water tank level led (W) or trip the failsafe to drop boost (F). You can do both at the same time if you solder link them.

Can you post the Voltage vs EGT Temperature chart here?

Where exactly is it?
In your circuit in the picture does not have a blue wire.
Draw a diagram.

In any case, connect the jumper, I disable the boost controller.
I understand you correctly?

Re: Datalogging HFS3v3
 

there are 6 wires in the green harness: Not shown on the drawing.

1. red ............. DI (+)
2. green .......... DI (-)
3. blue ............ Aux Failsafe
4. Yellow ......... Flow sensor signal (analogue)
5. White .......... Flow sensor raw pulses
6. Black .......... Signal ground

Here is a diagram:




EGT ........... 800C = ~2.6V (just above mid point on the AUXFS trimmer.

Just looked at the PLX-EGT sendor module , very set up. I will recommend this in the future. thanks for the link.

Re: Datalogging HFS3v3
 

Richard L thanks

I use PLX products for many years.
While serious problems with her I did not arise.

Re: Datalogging HFS3v3
 

Do you mean they are reliable?

Do you have a HFS3 or HFS4?

Re: Datalogging HFS3v3
 

Yes reliable.

I will buy HFS4.
HFS3 remain client.

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.
