30th t/a

I need some help setting up my wideband channel. I'm running an AEM 30-0300 X Series wideband and I'm running E85 fuel I need to know how to do the transform and what to select.

I've been trying to get this right for the past week with no success.

currently my wideband in the scanner reads 13.20 Lambda and the errors on my histogram are reading 1200s-1500s.

I know I have some things on the wrong setting but I don't know what to change. thanks

You might have to use lambda instead here. Does the gauge support E85? Otherwise, sounds like it's pretty lean... Has there been a tune already? What mods... Etc... Limited info here. I'm just guessing.

Im pretty sure I solved the problem. I originally had an input of .543 and an output of 10.3. I had a hunch that this might be the problem.
Well just for fun I selected the AEM wideband from the list, but let the function alone, as you see circled in red. Seems dead on now with my wideband gauge.

ChopperDoc

The .543 is your linear value.... the +/- 10.3 is the offset. For more check out my video on it... maybe it’s helpful. Always adjust the offset. Never the linear.

Ugh, I thought I had this ready to go but no. All I solved was getting the wideband on my channels list and functioning.
Im running E85 and my error values in the histogram are crazy high. Pretty sure its cause im running e85 and my stoich is set to 9.78.
Im also running the standard MPVI2 through a serial port/USB cable.

So when I go to add channel, I go to External inputs, Serial ports, AEM. Do I want EQ ratio or AFR?

thank you for the help

ChopperDoc

Use EQ ratio.

Okay, then I need to pick from the transformer selection list. I'm not sure which id want to select

I usually end up writing my own custom math functions for this reason. All I want is the volts off the input. From there I calculate myself. Allows me to enter the equation, and adjust what I am seeing if needed.

I have the WB in the channel list and the histogram setup, but the readings in both seem to be off.
I'm not sure if I have something set incorrectly in the Transform area or a math equation isn't setup properly??

Looks like your histogram isn't set up properly. Take a screenshot of that -
The main parameter you want is under Math - Lamba & AFR - EQ Ratio Error. Your X and Y look okay.

UPDATE:
I got the WB in the scanner working and the EQ Histogram working.
Things I found out to get this right.
The aem 30-0300 must be set to Lambda in order for the WB in the scanner to read Lambda.
Also, I had to change the input in the function box to 10. Output stayed at 0.
