The Megasquirt itself can take a wideband signal from any wideband controller that can output a 0-5V signal.
The important part is that the Megatune software needs to know the voltage/afr slope/curve in order to be able to use that wideband signal for both datalogging, and for calibrating the closed loop AFR table.
There are a number of options to choose from in the Megatune software at this time, the choices so far implemented are as follows:
#group LAMBDA_SENSOR "Lambda Sensor Type" # set NARROW_BAND_EGO "Narrowband Sensor" #unset DIY_TechE_NonL "DIY-WB or Tech Edge sensor giving a non-linear output" #unset TechEdge_Lin "Tech Edge sensor giving 0-5V 9-19:1 AFR" #unset Innovate1_2 "Innovate sensor giving 1-2V 10-20:1 AFR" #unset Innovate0_5 "Innovate sensor giving 0-5V 10-20:1 AFR" #unset WB_Non_Above "Wideband sensor but none of the above types" #endgroup
This is taken from the settings.ini file in the Megatune\carMtCfg directory. This is where you set your type of wideband sensor in use. Others can be added as long as the output is known.
