I’m helping a fellow C5 Corvette owner tune his LSA blower equipped LS1 via email.
He is using an AEM 30-0300 X series WB connected via a serial to USB.

We are fighting the typical rich/lean issue on decel caused by Min PW, Min Fuel Mg etc.

When it goes lean on decel, the WB numbers in the data can show 80:1 AFR.

Obviously that’s not real data, WB lean range is 20:1.

It really messes up the AFR error % when trying to use the histogram data.

Is this normal when using WB Via serial output? I don’t remember ever setting one up this way. I just use the analog output.

Thanks

I dont see that usually, all I use is serial widebands. But I'll have to double check I may have a filter turned on. I use lots of filters to clean up data logs and weed out bad data or cells with very low counts.

When you set up the WB in hpt, you can choose AFR or lambda. He chose AFR.
it comes up as user defined when you transform it.
Along with a formula.
He said he didn’t touch the formula.
I found it odd because that would assume an analog input.
I was just poking around, I don’t have any serial units.

I’m wondering if it’s set up wrong? Or if the serial data simply defaults to 80:1 when it goes past 20:1 on the display.

Certainly would be easier if I were hands on instead of trading emails. 😊

I don't remember having to do a transform when I added my innovate WB.

Thats how you set up analog, not serial.

Odd that comes up when selecting serial.

I’ll just work around the issue.
