Zetec MBE 956 Air/Fuel ratio logging

[Quinten]

I'm not even sure if I have a problem or not, but I would like to monitor my AFR.  Is this something that is possible in Easimap at all?  I had a look at the logging, but of course no 'AFR' option, so I probably need to look at a couple of parameters and log those?

Or is the *only* way to get an AFR gauge and wideband lambda?

My MBE could monitor it - but you will need a Wideband Lambda and controller regardless. One with a gauge is not a lot more than one without.

Hmm, guess I'll just have to give it a rest then...

[Quinten]

Had another thought, can I tell if I have a wide or narrowband lambda fitted by looking at the voltage reading in Easymap?  I know I am running open loop (as I checked the configuration), but I also know the lambda sensor reports some value in the logging screen...  I just can't recall what the value(s) was/were...

[Kingster]

Open loop means no need for lambda Doesn't it? Whereas closed loop uses lambda sensor to keep emissions in check.

i guess look on the exhaust and see what's bolted in to it.

[Quinten]

Correct, open loop = lambda disabled.  My exhaust has lambda fitted (4 wires), but from my understanding you can only tell by looking at the output voltage if it is wide or narrow?

The MBE956 uses a narrow-band sensor so nothing much useful gained by looking at the voltage
