lund nGauge, afr reading , wrong ?

[fifteen5oh]

So I noticed that the afr reading on the nGauge and the afr reading on the oe instrument cluster both read different. on 91 oct nGauge reads higher maybe .4-5 more that the oe cluster display. Also on e85 the n-Gauge wasn't reading in the 8's @ wot like the instrument cluster was.

I tried reading both banks on the nGauge and some results.


Anyone else?

This is the problem with afr. Switch ngauge to lambda if possible.

I have the same issue with the flex tune. On the dash cruising it reads between 13.7-14.3 that seams rich to me compared to factory tune. I still got to look at the ngauge readings this is on 93 octane

This screams rich to you? Stock usually runs about 14.5, right under stoich... My non-flex tune runs about 13.7-14.3, I wouldn't call that rich for me. I could be wrong though, I don't tune cars :shrug:

Correct me if I'm wrong, but those numbers are lean. The richer the mixture the lower the #.

Lean compared to WOT mixtures, yes. For cruising having the AFR in the 14.x range is perfectly fine.

you are correct. the factory gauge switches around 14.08, not 14.7.

I don't think there is an average afr on the Ngauge so you are reading left or right bank which is why it's off. I haven't seen an afr pid that is not bank 1 or 2

I was under the impression ford calibrated the stock sensor instrumentation to read e10 which is stoich at 14.1-14.2 the ngauge calibration is for regular gas 14.7 (stoich). I have my ngauge showing lambda which will report the same regardless of fuel..pump,e85 etc. Lund target .83 to.85 which is low to mid 12's afr on pump gas. If that is your tuner.
