"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. Quote:

Re: AUX input - IAT or WideBand o2?
Thanks for the order.
Are you good at soldering? |
Re: AUX input - IAT or WideBand o2?
yes.

Re: AUX input - IAT or WideBand o2?
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.
