PLX Device Voltages vs. AFR
I'm looking into figuring out a way to Datalog my DIY WB values but it does not corrispond with a PLX device mainly because it is non-linear.
Anybody have the reference voltage for the PLX device in the TE/ECUcontrol Plugging. That way when I log AFR I can Export to a ------ sheet and convert the AFRs to Voltages in Excel then Cross reference with the values I need.

I otherwords, I just want to log the voltage of the sensor, seeing as I can't do it straight up, I will log it as a PLX Device.
i don't believe ECUControl will car if the Sensor is linear or not rights, It's still going to log what it reads, and then I can interpret the values.v Right?
FYI: The DI-WB use the Honda VX Sensor.

Re: PLX Device Voltages vs. AFR
Okay I just found the equation from the PLX Site.
If I log a 15:1 AFR on a PLX Device thats
AFR=2*Voltage+10
Thus
Voltage is going to be
V=(15-10)/2
V=2.5volt
Take that to my sensor:
where 2.5 volts is 14.70AFR.
I have an equation for the Voltage to AFR for my sensor, so I won't alway have to reference to a chart, just copy and paste into cells.
Anyone see a problem with my theory.

Also If I have an equation to determine the Voltage to AFR could that not be written into ECUControl so that a non-linear device can be used? I'm not a Programming or ECU Genius so I don't now how the ECU would interpret this input?

Re: PLX Device Voltages vs. AFR
If you have a formula that converts it, yes... otherwise, if you're using a "Table" then that is a pain in the *** because it has to be statically compared.
The ECU also doesn't "do" anything with the information. ECUs do not interpret the WBO2 data...

That's what I thought.
I used Excel TrendLine to dtermine it, In comparisson it is on like xx.xx2 off, so not biggy. The widebands accuracy isn't even that exact.
What are the instructions for inputing WBo2 for Datalogging using TE/ECUControl?
