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.

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.

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?

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.

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

Thanks for the order.

Are you good at soldering?

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..??

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