Need help logging Stack AFR Gauge
I have a Stack wideband and I am trying to datalog thru a serial cable. I have tried several formulas but none have been accurate. It is a 0-4V with it ranging from 10:1 (0V) - 16:1 (4V) on a Linear scale. If anyone has any ideas it would be greatly appreciated.

The equation I came up with based on the voltage range is: 0.02349x+10
This is assuming 0.00-3.99v and 10.0-15.99 afr range.
Looking at the manual it states 0-4v and 6-20afr. Are you sure the above scale is what you are using?
If you are using the 6-20afr then you would want 0.054x+6
This is assuming 0.00-3.99v and 10.0-15.99 afr range.

Turns out the serial cable wasn't working well at all. I decided to junk it and run it right to the ecu, it was so simple i regret even buying the cable/adapter.
Anywho I cannot get the formula spot on but I am using .02956*x+9.6 and it is a tad bit richer so it shouldn't be a problem.
Thanks for the help!
