I have been trying to set up a histogram for my AEM AFR Gauge with no luck. I have watched several youtube videos and tried to research here on setting up the correct math but cant seem to get mine to display the proper calculations. I am running SD 3bar tune AEM wideband 03-300 set to AFR connect via serial port.
