Has anyone got this value to display. I don't get anything reported for either the Commanded or Measured sensors.

Is this value just not available from our ECU.

Cheers.

Correct. I have my torque pro with a bunch of mods and software updates. Never an afr reading from the 2zz. Also no afr with the k20. Id recommend just buying a wifeband to monitor that.

Pretty sure the Toyota 2ZZ doesn't use a wideband O2 sensor... Could be wrong.
So in that case you won't get an A:F, you'll only get voltage.

You could try entering the enhanced PID's into Torque.
But pretty sure they won't work, well you might be able to get the Commanded A:F and see what the ECU wants.


Open Loop Commanded Air/Fuel Ratio
OBD2 PID: 0144
Long Name: AFR
Short Name: AFR
Minimum Value: 0
Maximum Value: 20
Scale Factor: x1
Unit Type: A/F
Equation: (A*256+B)/32768*14.7


OEM Wideband Air/Fuel Ratio
OBD2 PID: 0134
Long Name: WAFR
Short Name: WAFR
Minimum Value: 0
Maximum Value: 20
Scale Factor: x1
Unit Type: A/F
Equation: (A*256+B)/32768*14.7

if its like the Evora, the ECU will give you your demanded AFR, but as stated above not your measured as you don't have a wideband.

Easy enough to add a wideband and torque will pick it right up but that'll require fastworks.

Like others have stated, there is no wideband on the car. Very rarely do they come with widebands. The only car that comes to mind that has one is the newer Mustang 5.0. You need to install a wideband sensor and a gauge in order to see it.

I'd kinda guessed that was the problem. Thanks guys for confirming it.

Which includes the fun and games of routing the cable (pipe) from the back through to the dash.

Cheers.

I use a PLX wideband A:F meter, you run the one wire to a gauge, and then can add many other sensors, daisy chained together, using that one.
