Graph Setup

I need info on how to setup the EQ Error graph

I'm using an Autometer Wideband o2 sensor.

If using hptuners in the channels list, right click on your wideband, go to transform, under eq ratio find your wideband. you need to populate your maf axis in histogram with the identical values from your maf voltge/frequency table in your calibration file found under engine/ airflow/general tabs

The most common issue with the EQ Error math function not working is when you bring in a wideband in the wrong units. From memory (I don't have my windows laptop with me) you can choose either AFR Error or EQ Error depending whether you want to view the air fuel ratio in units of AFR or Lambda.
