AFRvolt field

Post by ollykiwi3 »

does anyone know where the O2 or AFR volt field has gone with the new updates in MLV?
or has it been called something else?
I have looked in all the fields multiple times but cant find it.
I ran an old log file and it was there as "o2" as an option , but in my latest log , its not there.
thanks

MLV only displays what is in the datalog. So if a field is missing - you need to look at the program that created the datalog - TunerStudio.

Most likely you have changed your "Project Properties" to ask for AFR instead of O2 volts or changed from narrowband to wideband.

Ok thanks.
So does that mean I should display AFR volts on the dash board for mlv to pick it up?
I did change to wideband, how would that change the ability to display volts in mlv?

The firmware "ini" file uses your Project Properties-> Settings to determine what TunerStudio records into the log file.

Code: Select all

#if   NARROW_BAND_EGO
   entry = egoV,      "O2",          float,  "%.3f"
   entry = egoV2,      "O2-2",          float,  "%.3f"
#elif LAMBDA
   entry = lambda1,         "Lambda",      float,  "%.3f"
   entry = lambda2,         "Lambda2",      float,  "%.3f"
#else
   entry = afr1,            "AFR",         float,  "%.2f"
   entry = afr2,            "AFR2",         float,  "%.2f"
#endif

Sorry James but the last post is above my pay scale. Are you saying that because I now have wideband selected it won't display volts no matter what.

OR are you saying I need to create some ini file code to create it?

OR is it just a case of selecting the o2volts gauge to display in the dash?

What James was getting at is much simpler...

In TunerStudio open "Project Properties" by selecting:
File --> Project --> Project Properties
or
press CTRL+P

On the settings Tab, check what is set to "Oxygen Sensor / Display" or "EGO Sensor Selection" depending on your firmware.

Thanks. It's set up as oxy sensor/display and wideband selected.
So what does that mean for displaying O2 volts in MLV?
Should it appear?

ok.thanks.
is there a reason why the o2 volts was dropped when going from narrowband to wideband?
was it something people just werent using or not a function that was required to be seen. i would have thought it would be more useful with wideband than it would be for narrowband, but what do i know.
