What do you do if the afr wide band is different to the laptop

Hello i take it you are using a external wide band wired into your ecu and the gauge o your wideband dial gauge is reading different to what the ecu is seeing

you will need to work out why but normally we can sort it in the wiring you will need to wire the 12v and earth to see the same as the ecu uses this normally fixes it. but also check the calibration you are using in the ecu program,
