Ecu master classic

Hello .... how do I setup the aem xtype wideband in the ecu masterclassic

You would need to connect it this way :

Wideband -------> ECU

White Wire ----> Analog Input (you can choose the one you want)

Brown Wire ----> Sensor Ground

Then, in the sensor tab, oxygen sensor parameter, you select external controler, and select the fuel type. You select the analog input you connected your wideband to in the list. Finally you need to sent the calibration "AFR at 0V" and "AFR at 5V" according to the scaling formula at the page 13 of the manual. I always confirm the scaling that my wideband gauge reads the same as what I see in the ECU Master Software.
