When I datalog with the K-pro

the Wideband display work (via ELD input)

but the graph display of the AF doesn't work

how to make it work?

At a guess the minimum and maximum values for the AF display are wrong. Double click the AF sensor from the sensor window, check the 'display min' and 'display max'.

Does it display values in lambda instead of a/f?

the min and max value are 11/17

I try it today on a civic 2001 with K20a2, and the OEM RSX wideband and the graph templates AF value works

but with the aftermarket sensor Saturday the graph wasn'T working :?

Can you attach a datalog? I've done the external wideband on the s300, but not the k-pro. I've only used the rsx wideband on k-pro and k swapped cars. I'd be interested to see if I could figure out what it is doing.

Yes with the OEM wideband the datalog work at 100%

Can you upload / attach a datalog?

It will not graph the wideband reading via AF. Look at the ELD graph and scale it accordingly.

The graph is not currently showing the AF. A future release will probably address this.

I don't understand. This feature appears to work fine for me. I don't have any datalogs that have ACTUAL ELD.V input in them, but even at 0 volts CONSTANT on the ELD.V, I can get valid a/f numbers in my graph and display when I setup a custom wideband so 0 ELD.V means something special.

For instance, I set it up so 0 volts means 20:1 a/f with a custom conversion table in settings. I then reviewed a datalog that had 0 ELD.V constant. I setup the AF sensor to display on the graph and in display, and the a/f everywhere in the graph and when I click is 20:1 a/f. I can change the AF sensor display units to lambda and have it show me .5 to 1.5 and it comes out right at 1.36 which is 20:1.

As far as I can tell, this works exactly like it is supposed to -- exactly like I would expect having used this feature on the s300 on a dyno with a plx wideband (not eld.v obviously).

so it's impossible to me to see the AF datalog?

or just de Volts datalog?

Post your datalog and I will try to graph the a/f and put up screen shots on how I did it. This seriously does not seem broken when I try it.

i suppose that you already attach the white wire from your plxdevice to the ELD pin in the ecu?
