i am trying to get afr to log with me aem eugo and datalogit, and i cant get it to work. i think i have a problem with my settings or i am taking the wrong steps.

i have the wideband signal wire going to the AN-1 position on the datalogit, and the box is grounded to a chasis ground from the 0V position on the datalogit box.

when i make a log it will trace the position on the map and leave only zeros ( 0 ) in the log as if it is reading a steady 0 volt signal. i checked the voltage directly at the wire and it was reading voltage varying with the afr changes.

if someone who has experiance with using the system can give me a step by step of what to do, and lmk if i need to change settings that would be very hepful.

thanks.

The datalogit requires a differential signal for each of the analog inputs to measure accurately. Make sure you have both the signal and ground of the aem uego fed into the datalogit.

After that, you will need to enable the analog settings in the datalogit software, I believe it's a checkbox labeled "Sensors" or Adv. sensors or something like that.

After you enable the sensors, you have to setup the analog inputs i n the software to translate the voltage range of the uego into AFR readings.

Lastly, turn on map trace to view realtime cell by cell readings.

so i need to run the ground wire for the wideband to the datalogit box?

do you have any idea what the specific settings i need to input?
