Question Having trouble finding the right settings for my wideband

I have an MSPNP Gen 1 and an AEM X-series UEGO (30-0300) and none of the wideband presets seem to have the right voltage to AFR table, and theres no option to calibrate that I can find. Is there a way to do this in TS that I'm overlooking?

Thanks in advance,
Cam

yes. in sensor calibration, up in one of the top tabs. You can enter known 0-5 v signal, your aem should have those in the instructions or on line.

he has an ancient gen1, it's not that simple. you gotta go into the code and modify it, a gigantic pain in the butt

I've looked around in the code but I can't find anything that resembles it, I'll keep looking, will update when I figure it out, thanks guys

the following, I believe is the settings for the different widebands, this is changed to fix a problem with AEM widebands reading only in volts, but it isnt accurate, does anyone know what each value in the line actually represents?

#elif AEM_LINEAR
afrBins1 = array, U08, 0, [8x8], "AFR", 0.038666, 255.0, 10.0, 20.0, 1

Also, the following is my Voltage table, so that would make it not a 10->20 AFR reading, correct?

So I believe i should start by editting the 10 and 20 to 8.5 and 18?
Will try it when I get home, but Im mostly concerned about the decimal number because I have no idea what it represents.

interpolate to 0v and 5v and use those numbers. or search here for really old posts to see what we used to do back in like 2007 when this was an issue -- pretty sure we figured out a value that was really close.

OP, did you ever figure this out?

I'm working on converting my ancient MS1 from using volts to AFR, as described here: https://www.miataturbo.net/megasquir...t-table-28005/

I also came across the ""AFR", 0.038666, 255.0, 10.0, 20.0, 1" value, but not sure if it's accurate for my wbo2.

My wbo2 is the AEM(legacy) AEM-30-230x selection in TS. I too was wondering what the various values correlate to so that I can input the correct data.
