Missing AFR/Lambda value

Post by cider5 »

Again, I put it on wrong topic sorry.

Hello forum user, maybe someone can help me. My hardware is
Hondata V3 PRA Europe,
K20A2,
Plx wideband afr.
I converted my Lotus K20a2 to Plx wideband but use it as narrowband (pin A6, O2 sensor signal +). The O2 Voltage readout works fine (0,1V-0,9V).
Unfortunately I miss a Lambda or AFR value. Do I forgett anything in software settings or did I overlooked anything else?
Thanks for help.

You would need to input the wideband signal into one of the analog inputs. This will not allow you to run closed loop, but you will be able to see the AF reading from it.
