Calculate Analog Offsets for a Wideband

Post by VL400 »

Found this handy link for those wanting to calculate the linear offset with a wideband .. http://www.14point7.com/blogs/news/1653 ... megasquirt

The article and spreadsheet has TunerStudio and MegaSquirt references but is still valid for TunerPro and a Delco. The calculated AFR figures for 0V and 5V what is required in 12P and 11P.

If you are not using a 14point7 product and your wideband has the ability to output a fixed voltage (ie LM programmer and Innovate products) you can setup a test that outputs say 13.3 AFR during warmup and 16.6 AFR once warm. Noting what TunerPro reads and inputting the values to the spreadsheet.

This is perfect! Was actually wondering how to do this properly before I start using my wideband in the next few weeks.
Thanks!
