Re: AUX input - IAT or WideBand o2?
 

Grouped? I do not understand. Do you mean grouped electrically via the circuit board you showed me?


Looks like not. From the Innovate LC-2 user guide. And I am not sure I can reprogram it to be the inverse.

"Analog Output is configured as 0 volt = 7.35 AFR and 5 volts = 22.39 AFR"



Anyway, this is not sounding useful for my setup. I will probably just stick with the IDC as the trigger with IDC and MPS as the reference signals.

Re: AUX input - IAT or WideBand o2?
 

Grouped means the signal inversion.

- IAT sensor voltage goes lower as the temperature gets higher. (Inverted)
- EGT, WBO2, boost goes higher as the danger zone is approaching. (Non inverted)

This means the user manual is correct. No need to re-configure. You can not use the WBO2 signal to compensate and boost drop failsafe.

Remind me what car do you have.

Re: AUX input - IAT or WideBand o2?
 

I have the same WBO2 as the OP.

Are you saying that the WBO2 cannot be connected to trigger a failsafe and drop boost? (if 0V is rich and 5v is lean?)

or are you talking flow compensation?

Re: AUX input - IAT or WideBand o2?
 

You can do both at the same time.

Even the WBO2 signal is inverted, ie 0v=lean and 5v= rich, it can still be done by solder link on the HFS4-v3.1.

Re: AUX input - IAT or WideBand o2?
 

I just ordered my system and will be making this connection as well.

Re: AUX input - IAT or WideBand o2?
 

Thanks for the order.

Are you good at soldering?

Re: AUX input - IAT or WideBand o2?
 

yes.

Impressed!

Re: AUX input - IAT or WideBand o2?
 

Thanks but be more impressed that I resurrected a good old CD player for ~$16USD. Desoldering the anti-static shunt was a breeze. :)

So what bit of soldering are you alluding to here?

Are you referring to the wire connection between the WBO2 unit (brown wire of the Innovate LC-2) to the HFS-4's blue wire in the green harness? I think this is just a direct connection here unless you are suggesting something more..??

Re: AUX input - IAT or WideBand o2?
 

Linking two pads with solder, this might seem simple to you. Believe me, I have seen some real disasters of epic proportions.
