I have witnessed the readout on the Autronics unit display a given AFR reading. At that time I have checked the output voltage on the 0-5 volt output from the WB. It is correct using the pid in the generic sae folder. The formula is ({EXT.AD1*4})+10.
10:1~30:1 seems like an odd range for a wideband, but that's what my sae_generic.txt file says too. Still doesn't mean it's right. I'd check the documentation and see if the calibration of your WB out of the box is set to detect 10:1~30:1 on a 0-5v scale from the factory.
I then hooked the 0-5 volt output to the FS in which it sill is reading the correct voltage. Watching the logged voltage on FS, it matches the voltage measured from the 0-5 volt output. This is on the dashboard. Is there an issue with the way the dashboard see's these values?
I've yet to notice any issue with the dashboard having trouble reading a number from my LC1. Voltage is voltage plus or minus any ground offset you may be seeing.
I was told to check the data tab info and also build the MAP for BEN and look at the average.
If you're using the most recent version of EFILive, there should already be a BEN calc for an Autronic WB. Are you using these?
If I go and alter the pid in the generic folder, is that an acceptable way to readjust the readings? everything seems to be correct!
I've made adjustments to my sae_generic.txt file to account for ground offset in my WB. As long as you have everything in place and your formulas are right, I think it's ok to make changes here.
