Datalogging HFS3v3
 

Hello forum.
I have a question regarding HFS-3
How can i get data log of 0 to 5 Volt?

FIA2 Aquamist has a purple wire with voltage signal 0-100%

Second question:
Can i get 30 pin scheme (each pin purpose)
Are there any useful pins for data logging and data graph (i marked these pins with green on the photo)?

Thanks

Re: Datalogging HFS3v3
 

Here are some useful pins for data logging:

#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)

Thank you very much!
You could describe these pins in manual, so that would bring more customers

Re: Datalogging HFS3v3
 

Those pins are not static-protected so I rather use them as intended for remote diagnostic usage. They exist for the benefit for us and customer without working knowledge of our system but equipped with a simple $10 digital voltmeter.

It has been extremely useful since it was introduced.

For more knowledgeable users, all they need to do is ask here.

Richard L at 402 meters there is no time to consider devices.
Everything that happens with the engine we look at dataloge after racing.

What car is it? A 10s/quarter one?

Re: Datalogging HFS3v3
 

Yes

I include datalog

Re: Datalogging HFS3v3
 

Wow, very impressive! How much power?

I can seem to see the data datalog. It will be quite interesting.

Richard AUXFS control only HFS4?
HFS3 do not have it?

Interesting 11s log. Are you able to log the water flow now?

Only HFS4 has AUXFS.
