Wideband AFR Gauge

[AdamW]

I would try it first set to the "autroic mode P3" without any voltage divider as it may already have something similar built in to the gauge. Then do some logging and see how the traces look. If your logs look very noisy and/or low resolution (i.e steps) with it set up like that then you would change it to 0-5V output mode and connect the voltage divider inline which should improve it.

If you have "advanced tuning" enabled In the Motec software you can select what type of sensor/controller you have connected including a "user defined" choice.

on the few that I have done I have always needed to mess around a bit either adjusting the user defined table in the motec or reprograming the analog output of the controller to get the "lambda" reading in the motec to match the display on the controller.

So an M4 with advanced tuning is going to accept a 0-5v output in the user defined table, or does it always need the divider?
Thanks

No the wideband input is not 0-5v on the M4, I'm pretty sure the 10bit adc only covers a range of about 1.2v. The F1 help file on one of the wideband setup pages incorrectly suggests it is 0-5v but it is definitely not on any that I have tested. Note however I have never tested one of the more recent 3000+ serial numbered ecus so there is a small chance the newer versions accepted 5v.

Thanks Adam... so the help file is pretty incorrect!
Anyone from Motec confirming?!

I had both the innovate and now aem
The innovate controler worked well with motec but sensors would last few months at a time at £60 a go went threw 4 sensors then gave up and got aem the sensor is still going strong same tune over a year only problem is I can't seem to get stable reading with motec so I log seperat afr not a big deal for me

I did try to adjust the lambda adjustment to compensate I was way off so I just left it its aprox 0.3lamda off
Just my experience with it

And 1.2v is what my innovate was scaled to but resolution was low

Tech Edge says that the LSM-11 is just the normal output of a narrowband unit, 0 to 1v.
So would it be possible to feed the M4 a NB simulated output out of a WB controller?
Or does the LSM-11 have a particular voltage/lambda curve?
